我在homestead 內要啓動node寫的項目,我使用的是pm2 去運行和管理node 項目。使用pm2 的好處是方便調試和部署項目。不過homestead 裏面並無內置 pm2 功能,我只能本身安裝.前端
進入homestead 虛擬機(用 vagrant ssh 或者 使用shell工具 我推薦使用 finalshell 是一個很強大的免費工具)vue
安裝pm2node
npm install pm2@latest -g
這個時候會有個報錯shell
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! path /usr/local/lib/node_modules/pm2 npm ERR! code EACCES npm ERR! errno -13 npm ERR! syscall access npm ERR!

由於homestead 默認登錄的是 vagrant 用戶 。因此運行npm install pm2@latest -g 會報沒有權限的錯誤。npm
要切換到 root 用戶 或者 使用windows
sudo npm install pm2@latest
安裝。bash
我採用的是切換root 用戶,可是homestead沒有給root設置密碼,因此咱們要先設置下root 用戶的密碼ssh
sudo passwd root
而後用新設置的密碼登錄 root 用戶,安裝PM2.工具
安裝完成後, 初始化pm2this
pm2 init
會生成配置文件 ecosystem.config.js ,設置好項目配置文件.
啓動項目
pm2 start ecosystem.config.js
到這時候就能夠訪問node項目了。
不過有問題每次啓動homestead的時候都要到虛擬機裏面啓動pm2 仍是很麻煩還好 homestead 有相關的解決方案,在 homestead 目錄下有個 after.sh 的 shell 腳本就是用來啓動 homestead 後執行相關 shell 操做的。
我在裏面加內容
#!/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. # 切換到root 用戶 su root -c "root" # 啓動微課堂後臺前端項目 npm install pm2@latest -g # 啓動微課堂後臺前端項目 pm2 start ~/onlineducation.config.js
重啓 homestead 會報錯

su 命令只能在終端運行,看來只能用其餘方法切換用戶了。
修改 after.sh 腳本 使用 expect改爲可遠程執行的腳本
#!/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. # 安裝 expect sudo snap install expect # 安裝 pm2 sudo npm install pm2@latest -g # 切換到root 用戶 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 "
若是 expect 不能安裝,能夠進入虛擬機先安裝好,再重啓 homestead 就能夠了。
