centos/rhel下实现nginx自启动脚本实例

linux  /  管理员 发布于 7年前   168

通常在centos、rhel的OS下，我们大多是通过chkconfig来管理服务，比如开机自动启动服务之类。
这里给大家介绍一个很好用的nginx启动脚本。以及简单的使用，如下：

1. 执行如下命令：

vim /etc/init.d/nginxd

2.输入如下内容：

注意：该文件中的如下几个变量，都需要根据你实际的目录来改写。

nginx="/usr/local/nginx/sbin/nginx"  ##nginx的可执行文件路径lockfile="/var/nginx/nginx.lock"   ##需要先创建/var/nginx目录NGINX_CONF_FILE="/etc/nginx/nginx.conf" ##需要先创建该配置文件#!/bin/sh # # nginx - this script starts and stops the nginx daemon # # chkconfig:  - 85 15 # description: Nginx is an HTTP(S) server, HTTP(S) reverse \ #        proxy and IMAP/POP3 proxy server # processname: nginx # Source function library. . /etc/rc.d/init.d/functions # Source networking configuration. . /etc/sysconfig/network # Check that networking is up. [ "$NETWORKING" = "no" ] && exit 0 nginx="/usr/local/nginx/sbin/nginx" prog=$(basename $nginx) sysconfig="/etc/sysconfig/$prog" lockfile="/var/nginx/nginx.lock" pidfile="/var/nginx/${prog}.pid" NGINX_CONF_FILE="/etc/nginx/nginx.conf" [ -f $sysconfig ] && . $sysconfig start() {   [ -x $nginx ] || exit 5   [ -f $NGINX_CONF_FILE ] || exit 6   echo -n $"Starting $prog: "   daemon $nginx -c $NGINX_CONF_FILE   retval=$?   echo   [ $retval -eq 0 ] && touch $lockfile   return $retval } stop() {   echo -n $"Stopping $prog: "   killproc -p $pidfile $prog   retval=$?   echo   [ $retval -eq 0 ] && rm -f $lockfile   return $retval } restart() {   configtest_q || return 6   stop   start } reload() {   configtest_q || return 6   echo -n $"Reloading $prog: "   killproc -p $pidfile $prog -HUP   echo } configtest() {   $nginx -t -c $NGINX_CONF_FILE } configtest_q() {   $nginx -t -q -c $NGINX_CONF_FILE } rh_status() {   status $prog } rh_status_q() {   rh_status >/dev/null 2>&1 } # Upgrade the binary with no downtime. upgrade() {   local oldbin_pidfile="${pidfile}.oldbin"   configtest_q || return 6   echo -n $"Upgrading $prog: "   killproc -p $pidfile $prog -USR2   retval=$?   sleep 1   if [[ -f ${oldbin_pidfile} && -f ${pidfile} ]]; then     killproc -p $oldbin_pidfile $prog -QUIT     success $"$prog online upgrade"     echo      return 0   else     failure $"$prog online upgrade"     echo     return 1   fi } # Tell nginx to reopen logs reopen_logs() {   configtest_q || return 6   echo -n $"Reopening $prog logs: "   killproc -p $pidfile $prog -USR1   retval=$?   echo   return $retval } case "$1" in   start)     rh_status_q && exit 0     $1     ;;   stop)     rh_status_q || exit 0     $1     ;;   restart|configtest|reopen_logs)     $1     ;;   force-reload|upgrade)      rh_status_q || exit 7     upgrade     ;;   reload)     rh_status_q || exit 7     $1     ;;   status|status_q)     rh_$1     ;;   condrestart|try-restart)     rh_status_q || exit 7     restart     ;;   *)     echo $"Usage: $0 {start|stop|reload|configtest|status|force-reload|upgrade|restart|reopen_logs}"     exit 2 esac 

保存完毕之后，可以执行以下命令来启动nginx

chmod 777 /etc/init.d/nginxd /etc/init.d/nginxd start

3. 配置开机启动

执行以下命令：

chkconfig nginxd on

可以以下命令查看是否成功

chkconfig --list | grep nginxd
