如何在 Windows10 环境下部署配置一键启动的 Homestead + Laravel +vu

摘要：如何在环境下部署配置一键启动的项目我在内要启动写的项目，我使用的是去运行和管理项目。所以运行会报没有权限的错误。不过有问题每次启动的时候都要到虚拟机里面启动还是很麻烦还好有相关的解决方案，在目录下有个的脚本就是用来启动后执行相关操作的。

我在homestead 内要启动node写的项目，我使用的是pm2 去运行和管理node 项目。使用pm2 的好处是方便调试和部署项目。不过homestead 里面并没有内置 pm2 功能，我只能自己安装.

进入homestead 虚拟机（用 vagrant ssh 或者 使用shell工具 我推荐使用 finalshell 是一个很强大的免费工具）

安装pm2

npm install pm2@latest -g

这个时候会有个报错

npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules/pm2
npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules/pm2/node_modules
npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules

npm ERR!   syscall: "access",
npm ERR!   path: "/usr/local/lib/node_modules/pm2" }

npm ERR! A complete log of this run can be found in:
npm ERR!     /home/vagrant/.npm/_logs/2018-08-30T01_48_01_688Z-debug.log

因为homestead 默认登陆的是 vagrant 用户 。所以运行npm install pm2@latest -g 会报没有权限的错误。

要切换到 root 用户 或者 使用

sudo npm install pm2@latest

安装。

我采用的是切换root 用户，但是homestead没有给root设置密码，所以我们要先设置下root 用户的密码

sudo passwd root 

然后用新设置的密码登陆 root 用户，安装PM2.

安装完成后， 初始化pm2

pm2 init 

会生成配置文件 ecosystem.config.js ,设置好项目配置文件.

启动项目

pm2 start ecosystem.config.js

到这时候就可以访问node项目了。

不过有问题每次启动homestead的时候都要到虚拟机里面启动pm2 还是很麻烦还好 homestead 有相关的解决方案，在 homestead 目录下有个 after.sh 的 shell 脚本就是用来启动 homestead 后执行相关 shell 操作的。

我在里面加内容

#!/usr/bin/env bash
# If you would like to do some extra provisioning you may
# add any commands you wish to this file and they will
# be run after the Homestead machine is provisioned.

# 切换到root 用户
su root -c "root"

# 启动微课堂后台前端项目
npm install pm2@latest -g

# 启动微课堂后台前端项目
pm2 start ~/onlineducation.config.js

重启 homestead 会报错

su 命令只能在终端运行，看来只能用其他方法切换用户了。

修改 after.sh 脚本 使用 expect改成可远程执行的脚本

#!/usr/bin/env bash
# If you would like to do some extra provisioning you may
# add any commands you wish to this file and they will
# be run after the Homestead machine is provisioned.

# 安装 expect
sudo snap install expect

# 安装 pm2
sudo npm install pm2@latest -g

# 切换到root 用户
expect -c "
spawn su - root
expect ":"
send "root
"
expect ":"
send "cd /home/vagrant
"
expect ":"
send "pm2 start onlineducation.config.js
"
expect ":"
interact
"

如果 expect 不能安装，可以进入虚拟机先安装好，再重启 homestead 就可以了。
