CentOS配置nginx180

centos配置nginx1.8.0

• 环境准备

yum <span>-y</span> install gcc gcc<span>-c</span><span>++</span> autoconf automake make
yum <span>-y</span> install zlib zlib<span>-devel</span> openssl openssl<span>--</span>devel pcre pcre<span>-devel</span>

• 下载 nginx 、解压、编译并安装

wget  http://nginx<span>.org</span>/download/nginx-<span>1.8</span><span>.0</span><span>.tar</span><span>.gz</span>tar zxvf nginx-<span>1.8</span><span>.0</span><span>.tar</span><span>.gz</span>
cd nginx-<span>1.8</span><span>.0</span>
./configure
make && make install

• 启动nginx

/usr/<span>local</span>/nginx/sbin/nginx

此时，可以通过浏览器访问本机ip,会出现如下字段：

• 开机启动nginx

首先，在linux系统的/etc/init.d/目录下创建nginx文件，使用如下命令：
vi /etc/init.d/nginx
在脚本中添加如下命令：

下载

nginxd=<span>/usr/</span>local/nginx/sbin/nginx
nginx_c>/usr/</span>local/nginx/conf/nginx.conf
nginx_pid=<span>/var/</span>run/nginx.pid

接着，设置文件的访问权限：
chmod a+x /etc/init.d/nginx (a+x参数表示 ==> all user can execute 所有用户可执行)

最后将ngix加入到rc.local文件中，这样开机的时候nginx就默认启动了
vi /etc/rc.local
添加
/etc/init.d/nginx start
保存并退出
下次重启就会生效，实现nginx的自启动。
