Nginx启动脚本/重启脚本

1.介绍

    nginx 启动关闭，每次需要手动kill掉nginx,配置文件发生变化需要改变，提供该脚本解决问题

2.脚本

#!/bin/sh

#NGINX_HOME=`dirname $(cd "$(dirname "$0")"; pwd)`
NGINX_HOME='/usr/local/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="$NGINX_HOME/sbin/nginx" 
prog=$(basename $nginx) 

NGINX_CONF_FILE="$NGINX_HOME/conf/nginx.conf" 

lockfile=/var/lock/subsys/nginx 

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 $prog -QUIT 
    retval=$? 
    echo 
    [ $retval -eq 0 ] && rm -f $lockfile 
    return $retval 
} 

restart() { 
    configtest || return $? 
    stop 
    start 
} 

reload() { 
    configtest || return $? 
    echo -n $"Reloading $prog: " 
    killproc $nginx -HUP 
    RETVAL=$? 
    echo :wq
} 

force_reload() { 
    restart 
} 

configtest() { 
  $nginx -t -c $NGINX_CONF_FILE 
} 

rh_status() { 
    status $prog 
} 

rh_status_q() { 
    rh_status >/dev/null 2>&1 
} 

case "$1" in 
    start) 
        rh_status_q && exit 0 
        $1 
        ;; 
    stop) 
        rh_status_q || exit 0 
        $1 
        ;; 
    restart|configtest) 
        $1 
        ;; 
    reload) 
        rh_status_q || exit 7 
        $1 
        ;; 
    force-reload) 
        force_reload 
        ;; 
    status) 
        rh_status 
        ;; 
    condrestart|try-restart) 
        rh_status_q || exit 0 
            ;; 
    *) 
        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}" 
        exit 2 
esac

3.配置

    该脚本有两种方式部署，第一种放到/etc/init.d service启动，第二中放到 nginx bin目录下替代原来nginx 

3.1 service启动

将nginx脚本 复制到/etc/init.d/目录下，脚本名nginx

 赋予可执行权限 chmod +x /etc/init.d/nginx

检查一下/sbin/chkconfig nginx on; /sbin/chkconfig --list nginx

之后，就可以使用以下命令了

service nginx start
service nginx stop
service nginx restart
service nginx reload

/etc/init.d/nginx start
/etc/init.d/nginx stop
/etc/init.d/nginx restart

/etc/init.d/nginx reload

3.2 替换./sbin/nginx

     mv nginx /usr/local/nginx  /sbin/nginxs

     修改nginxs,改变NGINX_HOME值 

NGINX_HOME=`dirname $(cd "$(dirname "$0")"; pwd)`
#NGINX_HOME='/usr/local/nginx'

     chmod +x nginxs

     ./sbin/nginxs status

3.2.1 开启启动

   编辑  /etc/rc.local 放入

   /usr/local/nginx/sbin/nginxs start
