linux设置nginx开机自启动

1、在/etc/init.d/目录下新建文件nginx

下面的nginx文件内容标红的地方需要修改

• nginx="/usr/local/nginx/sbin/nginx" //修改成nginx执行程序的路径。
• NGINX_CONF_FILE="/etc/nginx/nginx.conf"  //修改成nginx.conf文件的路径。
• 如果是在windows中将nginx文件传到linux上。需要添加:set ff=unix 。否则会报错“env: /etc/init.d/nginx: 没有那个文件或目录”。出现这种问题就是因为文件格式不同造成的，或者使用另外一种方式也可以解决：删除nginx文件，使用vi编辑器新建文件把内容复制进去，然后设置755权限即可

nginx文件完整内容为（这是官网提供的加入系统服务脚本，链接 Red Hat NGINX Init Script）

#!/bin/sh

#

# nginx - this script starts and stops the nginx daemon

#

# chkconfig:   - 85 15

         useradd -M -s /bin/nologin $user

      fi

      options=`$nginx -V 2>&1 | grep 'configure arguments:'`

      for opt in $options; do

          if [ `echo $opt | grep '.*-temp-path'` ]; then

              value=`echo $opt | cut -d "=" -f 2`

              if [ ! -d "$value" ]; then

2、设置nginx文件可执行权限

chmod a+x /etc/init.d/nginx

3、将nginx服务加入chkconfig管理列表

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

加完这个之后，就可以使用service对nginx进行启动，重启等操作了

service nginx start

service nginx stop

service nginx restart

4、设置开机自启动

chkconfig nginx on
