Systemd mysql，nginx，php启动配置文件

systemctl的配置文件目录一般在

/usr/lib/systemd/system/

或者/etc/systemd/system/

需要注意的是，nginx与php运行用户必须是root，所以不需要添加运行用户，子进程会根据你对应配置设置的用户去运行

mysql配置如下

[Unit]
Description=MySQL Community Server
After=network.target
After=syslog.target
# 关机前操作
Before=shutdown.target

[Install]
WantedBy=multi-user.target
Alias=mysql.service

[Service]

User=mysql
Group=mysql
#systemctl status就是根据pid来判断服务的运行状态的
PIDFile=/usr/local/mysql/mysqld.pid
# 以root权限来启动程序
PermissionsStartOnly=true
# 设置程序启动前的必要操作。例如初始化相关目录等等
#ExecStartPre=/usr/bin/mysql-systemd-start pre
# 启动服务
ExecStart=/usr/local/mysql/mysqld start
ExecStop=/usr/local/mysql/mysqld stop
ExecReload=/usr/local/mysql/mysqld reload

# Don't signal startup success before a ping works
#ExecStartPost=/usr/bin/mysql-systemd-start post
# Give up if ping don't get an answer
TimeoutSec=600
#Restart配置可以在进程被kill掉之后，让systemctl产生新的进程，避免服务挂掉
Restart=on-failure
RestartSec=30
PrivateTmp=false
