小白系列：LNMP搭建

摘要：先来讲讲为啥子，要写这篇文章因为服务器操作系统，软件版本，以及需求，都千奇百怪。的模块使用来解析正则表达式该库提供了很多种压缩和解压缩的方式，使用对包的内容进行。

因为服务器操作系统，软件版本，以及需求，都千奇百怪。网上有很多教程每一种都不一样！而且按照上面傻瓜式复制粘贴操作完成安装的也在少数(本人用了很多但是没有一个傻瓜操作成功的) 基本上都是有些经验的遇到安装错误之后自行解决了！，所以我这面综合写一个文章（其实就是闲的）
闲话不多说，开始第一波操作

  毋庸置疑，在服务器进行一系列环境搭建之前，做好创建一个快照（就是系统的某一个时间点的所有备份，就跟照片一样，时间定格某一个画面），防止你的系统被你安装的乱七八糟的！到时候不好删，直接回滚磁盘来的方便！

云服务器( 栗子：阿里云 ）
创建办法：控制台->云服务器->选中你的实例->本实例的磁盘->创建快照 (这里如果你还找不到的话，听我的话放弃IT吧孩子)

使用办法：控制台->云服务器->选中你的实例->本实例的快照->回滚磁盘（这时候你的所有配置什么的环境啊，也都回滚了）

独立服务器
独立服务器，就是指你自己有的硬件服务器（通俗来讲就是，你能看到的实体的服务器）
这里不做推荐，因为如果你会搭建快照软件的话，这篇文章对你提升也不大！散了吧
如果你不会但是想学习一下的话，想了解一下的话可以看一下下面的链接
《10种linux下磁盘快照方式恢复系统》

  安装nginx 之前先确定好自己的服务器操作系统对应相对应的操作系统来做！

contos（本人用的是新的CentOS 7.4 64，其实个人感觉版本什么的安装程序差别不大）

1）用root用户 找到你的目录文件夹（本人推荐用root用户进行安装，不知道的 "cd ~"）

2）开始安装依赖(yum不知道是什么命令的，自己百度科普一下yum rpm 编译安装)

gcc:nginx编译依赖gcc环境
yum install -y gcc-c++ 

  pcre:(Perl Compatible Regular Expressions)是一个Perl库，包括 perl 兼容的正则表达式库。nginx的http模块使用pcre来解析正则表达式.
yum install -y pcre pcre-devel 

  zlib：该库提供了很多种压缩和解压缩的方式，nginx使用zlib对http包的内容进行gzip。
yum install -y zlib zlib-devel 

  openssl:一个强大的安全套接字层密码库，囊括主要的密码算法、常用的密钥和证书封装管理功能及SSL协议，并提供丰富的应用程序供测试或其它目的使用。nginx不仅支持http协议，还支持https（即在ssl协议上传输http）.
yum install -y openssl openssl-devel 

3)下载安装nginx（我这里是1.12的版本，大家可以自行选择）

wget http://nginx.org/download/nginx-1.12.0.tar.gz  下载安装包

tar -zxvf nginx-1.12.0.tar.gz                       解压安装包

cd nginx-1.12.0                                     找到解压  

   接下来是重点的部分
   注：安装之前需要手动创建上面指定的nginx文件夹，即/var/temp、/var/temp/nginx、/var/run/nginx/文件夹，否则启动时报错（如果不知道怎么新建文件夹《Linux 学习之创建、删除文件和文件夹命令》，或者用ftp创建也行)
  (为什么要这么做，因为这个是在网络上面比较好的一个安装目录，要不然就用yum安装了，安装之后别说nginx配置文件在哪？网站根目录在哪？如果不知道这些配置文件的用途 推荐你们看《Nginx编译参数大全 configure参数中文详解》)
./configure 
  --prefix=/usr/local/nginx 
  --pid-path=/var/run/nginx/nginx.pid 
  --lock-path=/var/lock/nginx.lock 
  --error-log-path=/var/log/nginx/error.log 
  --http-log-path=/var/log/nginx/access.log 
  --with-http_gzip_static_module 
  --http-client-body-temp-path=/var/temp/nginx/client 
  --http-proxy-temp-path=/var/temp/nginx/proxy 
  --http-fastcgi-temp-path=/var/temp/nginx/fastcgi 
  --http-uwsgi-temp-path=/var/temp/nginx/uwsgi 
  --http-scgi-temp-path=/var/temp/nginx/scgi  配置命令 （一起复制）

make && make install 编译并且编译安装

这就基本上可以了使用了

cd /usr/local/nginx/sbin/ 找到执行文件地方
./nginx                   启用nginx
   若报错：[emerg] open() "/var/run/nginx/nginx.pid" failed (2: No such file or directory)
   需要查看下是不是在 /var/run 文件夹下不存在 nginx 文件夹，不存在则新建
ps -ef | grep nginx 我们可以看一下这个是否启动成功了


  也就是证明你安装成功了
  启动成功后访问你的ip或者域名就能看到

  想要停止就要
cd /usr/local/nginx/sbin && ./nginx -s stop 强行停止
cd /usr/local/nginx/sbin && ./nginx -s quit 完整停止(建议使用)
cd /usr/local/nginx/sbin && ./nginx -s quit && ./nginx 重启
cd /usr/local/nginx/sbin && ./nginx -s reload 重新加载配置
   但是这样很麻烦，一般我们都会用shell做成服务，如果你嫌麻烦那么可以看一下如何封装成服务
service nginx restart 重启
service nginx stop  停止
service nginx start 启动
   这样是不是很帅，请看后续教程《小白系列：如何将软件装成service》

写累了，未完待续---2018-08-11

  开始安装php了

contos（本人用的是新的CentOS 7.4 64，其实个人感觉版本什么的安装程序差别不大）

1）回到到你的目录文件夹（不知道的 "cd ~"）

2）开始安装一些常用的php库

依次执行以下命令（常用的库，如果有什么要用的没有安装的，等安装完php后自己再独立安装也可以）
yum -y install libmcrypt-devel mhash-devel libxslt-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel 

3)下载并安装php（我这里是7.1.11的版本，大家可以自行选择）

wget http://cn2.php.net/distributions/php-7.1.11.tar.gz  下载php官方安装包(速度还是蛮快的说)

tar -zxvf php-7.1.11.tar.gz                       解压安装包

cd php-7.1.11                                     找到解压  

   开始配置编译参数

  ./configure 
   --prefix=/usr/local/php7 
   --with-config-file-path=/usr/local/php7/etc 
   --enable-fpm 
   --with-mcrypt 
   --enable-mbstring 
   --enable-pdo 
   --with-curl 
   --disable-debug  
   --disable-rpath 
   --enable-inline-optimization 
   --with-bz2  
   --with-zlib 
   --enable-sockets 
   --enable-sysvsem 
   --enable-sysvshm 
   --enable-pcntl 
   --enable-mbregex 
   --with-mhash 
   --enable-zip 
   --with-pcre-regex 
   --with-mysqli 
   --with-gd 
   --with-jpeg-dir 
   --with-freetype-dir 
   --enable-calendar  配置命令 （一起复制）

make && make install 编译并且编译安装(那这个时间就比较长了，我先去吃点东西~)

  直接启动会报错，先依次执行下面命令，将默认的配置文件变成真正的配置文件
cp /root/php-7.1.11/php.ini-production /usr/local/php7/etc/php.ini

cd /usr/local/php7/etc

cp php-fpm.conf.default php-fpm.conf

cd /usr/local/php7/etc/php-fpm.d

cp www.conf.default www.conf  

  需要查看下是不是在 /var/run 文件夹下不存在 php7文件夹，不存在则新建
  使用vim命令对php-fpm.conf的内容进行如下修改
cd /usr/local/php7/etc 找到配置文件夹
vim php-fpm.conf 打开后输入i进入编辑模式
pid = /run/php7/php-fpm.pid 
  （大概在17行左右，记住把前面的 ; 去掉,至于为什么在/run/php7/这，因为本人喜欢和nginx保持一致）
  之后按esc，在之后按shift+: 输入wq回车 （这文档编辑 就不在这教大家了）


cd /usr/local/php7/sbin && ./php-fpm 启动
  然后查看一下是否启动成功

  图上就表示启动成功了

  关闭比较麻烦
kill 进程id (注意关闭之前确认这个ID一定要，别关错了，【假装这里有一个苦笑的表情】)



  那么php就安装完了如果有人问到，为什么我php -v啥的不好使呢，这个跟windows一样,需要放在环境变量里面，这个和上个面的nginx都可以封装成系统的service，以下mysql也是一样！这样启动，和重启，关闭啥的就很简单了！请看后续教程《小白系列：如何将软件装成service》

该午休了，未完待续---2018-09-11

午休结束了，现在开始继续---2018-09-18

the first one
  都说建立专用的用户组来运行php和nginx那么好 我们去建立一个最常见到的www-data
groupadd www-data
useradd www-data -g www-data -s /sbin/nologin -M
  然后还是修改配置文件

the second one
  找到nginx的站点目录 /usr/local/nginx/html/
  新建一个文件叫phpinfo.php内容是 
  (此时如果要通过http://你的ip地址/phpinfo.php，他会默认给你下载下来这个php文件)

the thrid one
  找到nginx的配置文件夹/usr/local/nginx/conf中的nginx.conf
  编辑一下将其中的

  第二行的#user  nobody;
  改成user  www-data;

  第九行的#pid        logs/nginx.pid;
  改成 pid        /var/run/nginx/nginx.pid;

  将中间的
#location ~ .php$ {
#   root           html;
#    fastcgi_pass   127.0.0.1:9000;
#    fastcgi_index  index.php;
#    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
#    include        fastcgi_params;
#}

  改成这种
location ~ .php$ {
root           html;
fastcgi_pass   127.0.0.1:9000;
fastcgi_index  index.php;
fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
include        fastcgi_params;
}



the fourth one
  找到nginx的配置文件夹/usr/local/php7/etc/php-fpm.d中的www.conf
  将其中的23行24行
user = nobody
group = nobody
  改为
user = www-data
group = www-data




the end
  重启一下php
  然后重启一下nginx
  怎么重启我上面有写。这里就不重复了
  你在访问一下 就会发现http://你的ip地址/phpinfo.php 可以解析了
 具体的文件我放在下面，大家可以对比一下
 而且用户组也都变了

www.conf

; Start a new pool named "www".
; the variable $pool can be used in any directive and will be replaced by the
; pool name ("www" here)
[www]

; Per pool prefix
; It only applies on the following directives:
; - "access.log"
; - "slowlog"
; - "listen" (unixsocket)
; - "chroot"
; - "chdir"
; - "php_values"
; - "php_admin_values"
; When not set, the global prefix (or /usr/local/php7) applies instead.
; Note: This directive can also be relative to the global prefix.
; Default Value: none
;prefix = /path/to/pools/$pool

; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user"s group
;       will be used.
user = www-data
group = www-data

; The address on which to accept FastCGI requests.
; Valid syntaxes are:
;   "ip.add.re.ss:port"    - to listen on a TCP socket to a specific IPv4 address on
;                            a specific port;
;   "[ip:6:addr:ess]:port" - to listen on a TCP socket to a specific IPv6 address on

;   "port"                 - to listen on a TCP socket to all addresses
;                            (IPv6 and IPv4-mapped) on a specific port;
;   "/path/to/unix/socket" - to listen on a unix socket.
; Note: This value is mandatory.
listen = 127.0.0.1:9000

; Set listen(2) backlog.
; Default Value: 511 (-1 on FreeBSD and OpenBSD)
;listen.backlog = 511

; Set permissions for unix socket, if one is used. In Linux, read/write
; permissions must be set in order to allow connections from a web server. Many
; BSD-derived systems allow connections regardless of permissions.
; Default Values: user and group are set as the running user
;                 mode is set to 0660
;listen.owner = nobody
;listen.group = nobody
;listen.mode = 0660
; When POSIX Access Control Lists are supported you can set them using

; When set, listen.owner and listen.group are ignored
;listen.acl_users =
;listen.acl_groups =

; List of addresses (IPv4/IPv6) of FastCGI clients which are allowed to connect.
; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original
; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each address
; must be separated by a comma. If this value is left blank, connections will be
; accepted from any ip address.
; Default Value: any
;listen.allowed_clients = 127.0.0.1

; Specify the nice(2) priority to apply to the pool processes (only if set)
; The value can vary from -19 (highest priority) to 20 (lower priority)
; Note: - It will only work if the FPM master process is launched as root
;       - The pool processes will inherit the master process priority
;         unless it specified otherwise
; Default Value: no set
; process.priority = -19

; Choose how the process manager will control the number of child processes.
; Possible Values:
;   static  - a fixed number (pm.max_children) of child processes;
;   dynamic - the number of child processes are set dynamically based on the
;             following directives. With this process management, there will be
;             always at least 1 children.
;             pm.max_children      - the maximum number of children that can
;                                    be alive at the same time.
;             pm.start_servers     - the number of children created on startup.

;                                    state (waiting to process). If the number
;                                    of "idle" processes is less than this
;                                    number then some children will be created.
;             pm.max_spare_servers - the maximum number of children in "idle"
;                                    state (waiting to process). If the number
;                                    of "idle" processes is greater than this
;                                    number then some children will be killed.
;  ondemand - no children are created at startup. Children will be forked when
;             new requests will connect. The following parameter are used:
;             pm.max_children           - the maximum number of children that

;             pm.process_idle_timeout   - The number of seconds after which
;                                         an idle process will be killed.
; Note: This value is mandatory.
pm = dynamic

; The number of child processes to be created when pm is set to "static" and the
; maximum number of child processes when pm is set to "dynamic" or "ondemand".
; This value sets the limit on the number of simultaneous requests that will be
; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.
; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP
; CGI. The below defaults are based on a server without much resources. Don"t
; forget to tweak pm.* to fit your needs.
; Note: Used when pm is set to "static", "dynamic" or "ondemand"
; Note: This value is mandatory.
pm.max_children = 5

; The number of child processes created on startup.
; Note: Used only when pm is set to "dynamic"
; Default Value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2
pm.start_servers = 2

; The desired minimum number of idle server processes.
; Note: Used only when pm is set to "dynamic"
; Note: Mandatory when pm is set to "dynamic"
pm.min_spare_servers = 1

; The desired maximum number of idle server processes.
; Note: Used only when pm is set to "dynamic"
; Note: Mandatory when pm is set to "dynamic"
pm.max_spare_servers = 3

; The number of seconds after which an idle process will be killed.
; Note: Used only when pm is set to "ondemand"
; Default Value: 10s
;pm.process_idle_timeout = 10s;

; The number of requests each child process should execute before respawning.
; This can be useful to work around memory leaks in 3rd party libraries. For
; endless request processing specify "0". Equivalent to PHP_FCGI_MAX_REQUESTS.
; Default Value: 0
;pm.max_requests = 500

; The URI to view the FPM status page. If this value is not set, no URI will be
; recognized as a status page. It shows the following informations:
;   pool                 - the name of the pool;
;   process manager      - static, dynamic or ondemand;
;   start time           - the date and time FPM has started;
;   start since          - number of seconds since FPM has started;
;   accepted conn        - the number of request accepted by the pool;
;   listen queue         - the number of request in the queue of pending
;                          connections (see backlog in listen(2));
;   max listen queue     - the maximum number of requests in the queue
;                          of pending connections since FPM has started;
;   listen queue len     - the size of the socket queue of pending connections;
;   idle processes       - the number of idle processes;
;   active processes     - the number of active processes;
;   total processes      - the number of idle + active processes;
;   max active processes - the maximum number of active processes since FPM
;                          has started;
;   max children reached - number of times, the process limit has been reached,
;                          when pm tries to start more children (works only for
;                          pm "dynamic" and "ondemand");
; Value are updated in real time.
; Example output:
;   pool:                 www
;   process manager:      static
;   start time:           01/Jul/2011:17:53:49 +0200
;   start since:          62636
;   accepted conn:        190460
;   listen queue:         0
;   max listen queue:     1
;   listen queue len:     42
;   idle processes:       4
;   active processes:     11
;   total processes:      15
;   max active processes: 12
;   max children reached: 0
;
; By default the status page output is formatted as text/plain. Passing either
; "html", "xml" or "json" in the query string will return the corresponding
; output syntax. Example:
;   http://www.foo.bar/status
;   http://www.foo.bar/status?json
;   http://www.foo.bar/status?html
;   http://www.foo.bar/status?xml
;
; By default the status page only outputs short status. Passing "full" in the
; query string will also return status for each pool process.
; Example:
;   http://www.foo.bar/status?full
;   http://www.foo.bar/status?json&full
;   http://www.foo.bar/status?html&full
;   http://www.foo.bar/status?xml&full
; The Full status returns for each process:
;   pid                  - the PID of the process;
;   state                - the state of the process (Idle, Running, ...);

; Note: slowlog is mandatory if request_slowlog_timeout is set
;slowlog = log/$pool.log.slow

; The timeout for serving a single request after which a PHP backtrace will be
; dumped to the "slowlog" file. A value of "0s" means "off".
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
;request_slowlog_timeout = 0

; The timeout for serving a single request after which the worker process will
; be killed. This option should be used when the "max_execution_time" ini option
; does not stop script execution for some reason. A value of "0" means "off".
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0

; Set open file descriptor rlimit.
; Default Value: system defined value

; Chroot to this directory at the start. This value must be defined as an
; absolute path. When this value is not set, chroot is not used.
; Note: you can prefix with "$prefix" to chroot to the pool prefix or one
; of its subdirectories. If the pool prefix is not set, the global prefix
; will be used instead.
; Note: chrooting is a great security feature and should be used whenever
;       possible. However, all PHP paths will be relative to the chroot
;       (error_log, sessions.save_path, ...).
; Default Value: not set
;chroot =

; Chdir to this directory at the start.
; Note: relative path can be used.

; process time (several ms).
; Default Value: no
;catch_workers_output = yes

; Clear environment in FPM workers
; Prevents arbitrary environment variables from reaching FPM worker processes
; by clearing the environment in workers before env vars specified in this
; pool configuration are added.
; Setting to "no" will make all environment variables available to PHP code
; via getenv(), $_ENV and $_SERVER.
; Default Value: yes
;clear_env = no

; Limits the extensions of the main script FPM will allow to parse. This can
; prevent configuration mistakes on the web server side. You should only limit
; FPM to .php extensions to prevent malicious users to use other extensions to
; execute php code.
; Note: set an empty value to allow all extensions.
; Default Value: .php
;security.limit_extensions = .php .php3 .php4 .php5 .php7

; Pass environment variables like LD_LIBRARY_PATH. All $VARIABLEs are taken from
; the current environment.

; Additional php.ini defines, specific to this pool of workers. These settings
; overwrite the values previously defined in the php.ini. The directives are the
; same as the PHP SAPI:
;   php_value/php_flag             - you can set classic ini defines which can
;                                    be overwritten from PHP call "ini_set".
;   php_admin_value/php_admin_flag - these directives won"t be overwritten by
;                                     PHP call "ini_set"
; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.

; Defining "extension" will load the corresponding shared extension from
; extension_dir. Defining "disable_functions" or "disable_classes" will not
; overwrite previously defined php.ini values, but will append the new value
; instead.

; Note: path INI options can be relative and will be expanded with the prefix
; (pool, global or /usr/local/php7)

; Default Value: nothing is defined by default except the values in php.ini and
;                specified at startup with the -d argument
;php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f www@my.domain.com
;php_flag[display_errors] = off
;php_admin_value[error_log] = /var/log/fpm-php.www.log
;php_admin_flag[log_errors] = on
;php_admin_value[memory_limit] = 32M
