centos7把編譯安裝的服務通過systemctl管理

nginx編譯安裝的目錄是/usr/local/nginx

nginx配置文件是/usr/local/nginx/conf/nginx.conf

systemctl管理的服務文件在/usr/lib/systemd/system下

進入目錄vim nginx.service，寫下如下的代碼

[Unit]
Description=The NGINX HTTP and reverse proxy server
After=syslog.target network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
PIDFile=/usr/local/nginx/logs/nginx.pid   
ExecStartPre=/usr/local/nginx/sbin/nginx -t
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/usr/bin/kill -s QUIT $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target

　　先pkill nginx殺死用/usr/local/nginx/sbin/nginx腳本啟動的服務

      再用systemctl start nginx啟動服務

mysql編譯安裝

目錄在/usr/local/mysql  配置文件在/etc/my.cnf

vim mysql.service寫入代碼

[Unit]
Description=MySQL Server
#Documentation=man:mysqld(8)
#Documentation=http://dev.mysql.com/doc/refman/en/using-systemd.html
After=network.target
After=syslog.target

[Install]
WantedBy=multi-user.target

[Service]
User=mysql  #啟動服務的用戶，主機要有mysql用戶
Group=mysql
ExecStart=/usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf
LimitNOFILE = 5000

　　修改過mysql.service文件需要先執行systemctl daemon-reload

        再通過systemctl start mysql啟動服務
