Nginx手动启动
停止操作
停止操作是通过向nginx进程发送信号（什么是信号请参阅linux文 章）来进行的
步骤1：查询nginx主进程号
ps -ef | grep nginx
在进程列表里 面找master进程，它的编号就是主进程号了。
步骤2：发送信号
从容停止Nginx：
kill -QUIT 主进程号
快速停止Nginx：
kill -TERM 主进程号
强制停止Nginx：
pkill -9 nginx
另外， 若在nginx.conf配置了pid文件存放路径则该文件存放的就是Nginx主进程号，如果没指定则放在nginx的logs目录下。有了pid文 件，我们就不用先查询Nginx的主进程号，而直接向Nginx发送信号了，命令如下：
kill -信号类型 '/usr/nginx/logs/nginx.pid'
命令：/usr/local/nginx/sbin/nginx
若出现：
[root@kangxiaowei ~]# /usr/local/nginx/sbin/nginx
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: still could not bind()
则再次执行 /root/lnmp stop关闭lnmp即可
Nginx的开机启动脚本
开机自动启动nginx，
如果需要开机启动服务，保存好 /etc/init.d/nginx文件后，
执行以下命令:
代码如下 复制代码
chkconfig --add ningx
chkconfig --level nginx 2345 on
开机自动启动脚本
代码如下 复制代码
#! /bin/sh
# chkconfig: 2345 55 25
# Description: Startup script for nginx webserver on Debian. Place in /etc/init.d and
# run 'update-rc.d -f nginx defaults', or use the appropriate command on your
# distro. For CentOS/Redhat run: 'chkconfig --add nginx'
### BEGIN INIT INFO

# Default-Stop: 0 1 6

do_start() {
$DAEMON -c $CONFIGFILE || echo -n "nginx already running"
}
do_stop() {
kill -INT `cat $PIDFILE` || echo -n "nginx not running"
}
do_reload() {
kill -HUP `cat $PIDFILE` || echo -n "nginx can't reload"
}
case "$1" in
start)
echo -n "Starting $DESC: $NAME"
do_start
echo "."
;;
stop)
echo -n "Stopping $DESC: $NAME"
do_stop
echo "."

echo -n "Reloading $DESC configuration..."
do_reload

echo -n "Restarting $DESC: $NAME"
do_stop
do_start
echo "."
;;
*)
echo "Usage: $SCRIPTNAME {start|stop|reload|restart}" >&2
exit 3
;;
esac
exit 0
需要你修改的配置有
代码如下 复制代码
#! /bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
NAME=nginx
DAEMON=/usr/local/nginx/sbin/$NAME
CONFIGFILE=/usr/local/nginx/conf/$NAME.conf
PIDFILE=/usr/local/nginx/logs/$NAME.pid
编辑好后保存，执行以下命令
代码如下 复制代码
1 chmod +x /etc/init.d/nginx
现在把Nginx加入chkconfig，并设置开机启动。
代码如下 复制代码
12 chkconfig --add nginx chkconfig nginx on
# 检查一下
代码如下 复制代码
1 chkconfig --list nginx
nginx 0:off 1:off 2:on 3:on 4:on 5:on 6:off
