linux下nginx开启service命令

之前配置了php-fpm的service命令，现在记录下nginx的service命令配置，毕竟nginx是现在主流的反向代理、负载均衡服务器，重启啥的太长用了。

开始盘它

第一步

cd /etc/init.d/ 目录下
使用 vim nginx 编写nginx文件

第二步

编辑的文件中的nginxd、nginx_config、nginx_pid 等依据系统安装的文件的路径来配置

#!/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

第三步

执行以下命令

chkconfig --add /etc/init.d/nginx
chmod 755 /etc/init.d/nginx
chkconfig --add nginx

第四步

执行service nginx 测试是否有service命令执行报错，如果没有错误，则会出现提示信息

nginx启动、停止、无间断服务重启，可选 start | stop | restart | reload | status | help

常用命令

nginx启动命令：service nginx start
nginx停止命令：service nginx stop
nginx重启命令：service nginx reload
