2、mysql

4、redis

vim /etc/rc.d/init.d/redis

vim /lib/systemd/system/redis.service

[Unit]Description=redisAfter=network.target[Service]Type=forkingExecStart=/etc/init.d/redis startExecReload=/etc/init.d/redis restartExecStop=/etc/init.d/redis stopPrivateTmp=true[Install]WantedBy=multi-user.target

5、说明

1、创建自启动脚本以后都要给可执行权限，如：

chmod a+x /etc/init.d/nginx chmod a+x /etc/init.d/php-fpm

2、服务文件说明

[Unit]:服务的说明Description:描述服务After:描述服务类别[Service]服务运行参数的设置Type=forking是后台运行的形式ExecStart为服务的具体运行命令ExecReload为重启命令ExecStop为停止命令PrivateTmp=True表示给服务分配独立的临时空间注意：[Service]的启动、重启、停止命令全部要求使用绝对路径[Install]服务安装的相关设置，可设置为多用户

3、服务文件目录：

/lib/systemd/system  

4、命令说明：

启动nginx服务systemctl start nginx.service设置开机自启动systemctl enable nginx.service停止开机自启动systemctl disable nginx.service查看服务当前状态systemctl status nginx.service重新启动服务systemctl restart nginx.service查看所有已启动的服务systemctl list-units --type=service
