完成了Nginx的编译安装后，仅仅是能支持Nginx最基本的功能，为了在生产环境应用，还需要进行一些额外的设置。

设置系统服务

每次进入nginx的home目录进行nginx的开启、关闭、重载非常不方便，所以，我们需要注册系统服务，来避免此类问题。

进入nginx目录，创建系统服务文件：

cd /comexHome/nginx
vim nginx4comex

然后输入如下内容后wq退出

#!/bin/sh
# Name:nginx4comex
# nginx - this script starts and stops the nginx daemon
#
# description:  Nginx is an HTTP(S) server, HTTP(S) reverse \
#               proxy and IMAP/POP3 proxy server
# processname: nginx
# config:      /comexHome/nginx/conf/nginx.conf
# pidfile:     /comexHome/nginx/nginx.pid
#
# Created By http://comexchan.cnblogs.com/

# 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_DAEMON_PATH="/comexHome/nginx/sbin/nginx"
NGINX_CONF_FILE="/comexHome/nginx/conf/nginx.conf"
NGINX_LOCK_FILE="/var/lock/subsys/nginx4comex"
prog=$(basename $NGINX_DAEMON_PATH)

start() {
    [ -x $NGINX_DAEMON_PATH ] || exit 5
    [ -f $NGINX_CONF_FILE ] || exit 6
    echo -n $"Starting $prog: "
    daemon $NGINX_DAEMON_PATH -c $NGINX_CONF_FILE
    retval=$?
    echo
    [ $retval -eq 0 ] && touch $NGINX_LOCK_FILE
    return $retval
}

stop() {
    echo -n $"Stopping $prog: "
    killproc $prog -QUIT
    retval=$?
    echo
    [ $retval -eq 0 ] && rm -f $NGINX_LOCK_FILE
    return $retval
}

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

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

force_reload() {
    restart
}

configtest() {
  $NGINX_DAEMON_PATH -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

授予执行权限：

chmod u+x /comexHome/nginx/nginx4comex

移动到系统服务目录

cp /comexHome/nginx/nginx4comex /etc/init.d

测试系统服务：

# 查看nginx状态
service nginx4comex status
# 停止nginx服务
service nginx4comex stop
# 启动nginx服务
service nginx4comex start
# 重启nginx服务(停机)
service nginx4comex restart
# 重载Nginx服务(不停机)
service nginx4comex reload
# 测试配置文件是否合法
service nginx4comex configtest
# 强制重新加载新配置(停机)
service nginx4comex force-reload
