Linux下Nginx开关，正常方式是这样（{nginx}-为Nginx安装路径）：
｛nginx｝/sbin/nginx #启动
｛nginx｝/sbin/nginx -s stop #停止
这种方式带来很多不便，因此介绍一种快捷启动关闭Nginx的方式。
在/etc/init.d下创建nginx启动脚本文件:
vim /etc/init.d/nginx
i进入编辑状态，粘贴以下代码后保存：
将/usr/local/nginx/替换为自身nginx的安装路径。
#!/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
# config: /etc/nginx/nginx.conf
# config: /etc/sysconfig/nginx
# pidfile: /var/run/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"
[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx

start() {
[ -x $nginx ] || exit 5

echo -n $"Starting $prog: "

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
killall -9 nginx
}
restart() {
configtest || return $?
stop
sleep 1
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

exit 2
esac
修改脚本权限：
chmod 755 nginx
将脚本文件加入到chkconfig中：
chkconfig --add nginx
设置nginx开机在3和5级别自动启动：
chkconfig --level 35 nginx on
创建软连接：
cd /usr/bin
ln -s /etc/init.d/nginx
愉快的玩耍吧！
这里边的命令都可以执行:
echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
以下是示例：
nginx start
nginx stop
nginx restart
