一般情况，安装好 Nginx 后，使用它的命令是 它的路径+对应的命令 ，但路径很长，每次使用都很麻烦，现在添加一个 service nginx xxx 的方式，简单快捷，在很多教程中也是如此使用。

新建 nginx 文件

在本地创建一个文件，命名为 nginx ，内容如下

注意

nginx=”/usr/local/nginx/sbin/nginx”

NGINX_CONF_FILE=”/usr/local/nginx/conf/nginx.conf”

路径是否对应上了

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemin
#
# chkconfig: - 85 15
# description: Nginx is an HTTP(S) server, HTTP(S) reverse \
# proxy and IMAP/POP3 proxy server
# processname: nginx
# config: /usr/local/nginx/conf/nginx.conf
# pidfile: /usr/local/nginx/logs/nginx.pid

# 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)

NGINX_CONF_FILE="/usr/local/nginx/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
}

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

然后上传文件到 /etc/init.d/ 目录下。

使用命令

如果此时直接使用 service nginx restart 之类的命令，应该会报错。

## env: /etc/init.d/nginx: 权限不够
## 执行以下命令

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

## 现在
service nginx restart

## 就没问题了
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
Stopping nginx:                                            [  OK  ]
Starting nginx:                                            [  OK  ]

棒棒哒..
