服务启动、停止和重启脚本

Ubuntu 14.04.2 LTS 启动脚本

PHP-FPM 服务

  • 下载文件php-fpm.sh

  • 注意配置文件：sudo vim /usr/local/php-7.2/etc/php-fpm.conf

    务必开启配置文件的pid路径：pid = run/php-fpm.pid
      否则会报错：no pid file found - php-fpm is not running ? 

  • CP到默认开启的服务脚本：

    sudo cp php-fpm.sh  /etc/init.d/php-fpm

  • 给予权限：

    sudo chmod +x /etc/init.d/php-fpm

  • 使用sysv-rc-conf安装，如何安装sysv-rc-conf管理服务

  • php-fpm.sh代码

  • 运行效果

Nginx 服务

  • 第一种安装方式

    • 查看当前nginx是否已经在开机启动项里面: 
    ls /etc/rc*
    • 如何安装
    #使用wget -O 下载并以不同的文件名保存 
sudo wget https://raw.github.com/JasonGiedymin/nginx-init-ubuntu/master/nginx -O /etc/init.d/nginx
# 给与权限   
sudo chmod +x /etc/init.d/nginx
# 设置为启动项
sudo update-rc.d nginx defaults

    • 需要修改的地方：

    • 1、NGINXPATH=${NGINXPATH:-/opt/openresty/nginx} 修改为自己的路径

    • 2、PIDSPATH=${PIDSPATH:-$NGINXPATH/logs} pid文件路径

      如果在配置文件修改为：pid /run/nginx.pid;
              PIDSPATH=${PIDSPATH:-$NGINXPATH/logs}修改为：PIDSPATH="/run"

  • 第二种安装方式

    • 和PHP-FPM一样，nginx.sh代码

  • 根据自己环境，配置文件路径，下面修改为Openresty下的Nginx启动项(Nginx 安装在/usr/local/openresty/目录下)

    sudo vim /etc/init.d/nginx
NGINXPATH=${NGINXPATH:-/usr/local/openresty/nginx}

  • 开启服务

    sudo service nginx restart
[sudo] password for www: 
* Stopping Nginx Server...      [ OK ] 
* Starting Nginx Server...      [ OK ]

Ubuntu 16.04.2 LTS 启动脚本

PHP-FPM 服务

  • php-fpm.sh脚本代码 同上

  • 注意，需要重新加载服务：

    sudo systemctl daemon-reload

  • 开启服务

    sudo systemctl start php-fpm.service

  • 停止服务

    sudo systemctl stop php-fpm.service

  • 重启服务

    sudo systemctl restart php-fpm.service

  • 服务状态

    sudo systemctl status php-fpm.service

Nginx 服务

  • Debian/Ubuntu Nginx init Script

    [1]通常情况下，如果你从存储库安装Nginx，这个初始化脚本已经包含在内。但是，如果您从源代码安装，或者没有使用标准路径，您可能需要这个。
    [2]如果发现停止/重新启动等不起作用，则您的pid文件位置可能不正确。您可以将其设置在nginx.conf中，也可以在此处更改init脚本以指向正确的pid位置
