Nginx 最全小白实战教程之一 （安装篇）

摘要：一环境准备操作系统位版本二安装下载解压新建用户与组组编译配置文件安装重定向支持和支持，如果不需要可以不安装。

操作系统：Centos6.4 64位

Nginx版本：1.4.2

[root@localhost nginx]# cd /usr/local/
[root@localhost nginx]# mkdir nginx
[root@localhost nginx]# cd nginx
[root@localhost nginx]# wget http://nginx.org/download/nginx-1.4.2.tar.gz

[root@localhost nginx]# tar xf nginx-1.4.2.tar.gz

[root@localhost nginx]# groupadd -g 108 -r nginx
You have new mail in /var/spool/mail/root
[root@localhost nginx]# useradd -u 108 -r -g 108 nginx
[root@localhost nginx]# id nginx
uid=108(nginx) gid=108(nginx) 组=108(nginx)

安装prce(重定向支持)和openssl(https支持，如果不需要https可以不安装。)

[root@localhost nginx]# yum install -y pcre-devel openssl-devel
[root@localhost nginx]# cd  nginx-1.4.2
[root@localhost nginx-1.4.2]# ./configure

[root@localhost nginx-1.4.2]# make && make install

[root@localhost nginx]# vi /etc/init.d/nginx

脚本一定要写成这样，否则会出错的

脚本处理：

[root@localhost init.d]# chmod +x nginx
[root@localhost init.d]# chkconfig --add nginx
[root@localhost init.d]# chkconfig nginx on
[root@localhost init.d]# service nginx start

然后访问：

推荐使用这种方法，上一种方法折腾了一晚上呢，之后的教程以此方法为主

[root@localhost ~]# vi /etc/yum.repos.d/nginx.repo

在文件中写入

[nginx] 
name=nginx repo  
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/  
gpgcheck=0  
enabled=1  

然后

[root@localhost ~]# sudo yum install nginx -y 
[root@localhost ~]# sudo service nginx start
[root@localhost ~]# sudo chkconfig nginx on
