Linux下Nginx开机自启动

开机自启动nginx

这里使用的是编写shell脚本的方式来处理

vi /etc/init.d/nginx (输入下面的代码)

#!/bin/bash
# nginx Startup script for the Nginx HTTP Server
# it is v.0.0.2 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: /var/run/nginx.pid
# config: /usr/local/nginx/conf/nginx.conf
nginxd=/usr/local/nginx/sbin/nginx
nginx_config=/usr/local/nginx/conf/nginx.conf
nginx_pid=/var/run/nginx.pid
RETVAL=0
prog=”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 /var/lock/subsys/nginx
return $RETVAL
}
# Stop nginx daemons functions.
stop() {
echo -n $”Stopping $prog: ”
killproc $nginxd
RETVAL=$?
echo
[ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /var/run/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

:wq 保存并退出

设置文件的访问权限

chmod a+x /etc/init.d/nginx (a+x ==> all user can execute 所有用户可执行)

这样在控制台就很容易的操作nginx了：查看Nginx当前状态、启动Nginx、停止Nginx、重启Nginx…

同样的修改了nginx的配置文件nginx.conf，也可以使用上面的命令重新加载新的配置文件并运行，可以将此命令加入到rc.local文件中，这样开机的时候nginx就默认启动了

vi /etc/rc.local

加入一行 /etc/init.d/nginx start 保存并退出，下次重启会生效。
