如何在 windows10 环境下部署配置一键启动的 Homestead + Laravel +vue + PM2 项目

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 ERR!   path: '/usr/local/lib/node_modules/pm2' }

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\r\"
expect \":\"
send \"cd \/home\/vagrant\r\"
expect \":\"
send \"pm2 start onlineducation.config.js\r\"
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。
