nginx開機啟動

Nginx

nginx開機啟動使用的是編寫shell指令碼的方式來處理，如下：

[root@mycentos ~]# vi /etc/init.d/nginx
#!/bin/bash
# nginx Startup script for the Nginx HTTP Server
# it is v.1.11.3 version.
# chkconfig: - 85 15
# description: Nginx is a high-performance web and proxy server.
#              It has a lot of features, but it's not for everyone.
# processname: nginx
# pidfile: /usr/local/nginx/logs/nginx.pid
# config: /usr/local/nginx/conf/nginx.conf

#nginx path
nginxd=/usr/local/nginx/sbin/nginx

#nginx config
nginx_config=/usr/local/nginx/conf/nginx.conf

#nginx pid path, it is in nginx.conf.
nginx_pid=/usr/local/nginx/logs/nginx.pid
RETVAL=0
prog="nginx"

#nginx lockfile
lockfile=/var/lock/subsys/nginx

# Source function library.
. /etc/rc.d/init.d/functions

# Source networking configuration.
. /etc/sysconfig/network

# Check that networking is up.
[ ${NETWORKING} = "no" ] && exit 0
[ -x $nginxd ] || exit 0

# Start nginx daemons functions.
start() {
if [ -e $nginx_pid ];then
　　echo "nginx already running...."
　　exit 1
fi
　　echo -n $"Starting $prog: "
　　daemon $nginxd -c ${nginx_config}
　　RETVAL=$?
　　echo
　　[ $RETVAL = 0 ] && touch $lockfile
　　return $RETVAL
}
# Stop nginx daemons functions.
stop() {
　　echo -n $"Stopping $prog: "
　　killproc $nginxd
　　RETVAL=$?
　　echo
　　[ $RETVAL = 0 ] && rm -f $lockfile $nginx_pid
}
# reload nginx service functions.
reload() {
　　echo -n $"Reloading $prog: "
　　#kill -HUP `cat ${nginx_pid}`
　　killproc $nginxd -HUP
　　RETVAL=$?
　　echo
}
# See how we were called.
case "$1" in
start)
　　start
　　;;
stop)
　　stop
　　;;
reload)
　　reload
　　;;
restart)
　　stop
　　start
　　;;
status)
　　status $prog
　　RETVAL=$?
　　;;
*)
　　echo $"Usage: $prog {start|stop|restart|reload|status|help}"
　　exit 1
esac
exit $RETVAL
#設定檔案的訪問許可權
chmod a+x /etc/init.d/nginx   #(a+x ==> all user can execute  所有使用者可執行)

#這樣在控制檯就很容易的操作nginx了：檢視Nginx當前狀態、啟動Nginx、停止Nginx、重啟Nginx。
#同樣的修改了nginx的配置檔案nginx.conf，也可以使用上面的命令重新載入新的配置檔案並執行，可以將此命令加入到rc.local檔案中，這樣開機的時候nginx就預設啟動了。

[root@mycentos ~]# vi /etc/rc.local
/etc/init.d/nginx start #儲存並退出，下次重啟會生效。
