centos 7 下安装Nginx

下载Nginx

wget nginx.tar.gz http://nginx.org/download/nginx-1.11.3.tar.gz

 解压源码

tar -zxvf nginx-1.11.3.tar.gz

然后进入目录编译安装
cd nginx-1.11.3
./configure --prefix=/usr/local/nginx 
--with-http_ssl_module --with-http_spdy_module 
--with-http_stub_status_module --with-pcre
如果没有error信息，就可以执行下边的安装了：
make
make install

安装prce(重定向支持)和openssl(https支持，如果不需要https可以不安装。)

yum -y install pcre*
yum -y install openssl*

启动nginx
./usr/local/nginx/sbin/nginx

重启或关闭进程：
./usr/local/nginx/sbin/nginx -s reload
./usr/local/nginx/sbin/nginx -s stop

浏览器中输入http://localhost:8080，效果如下

官方文档中的安装方法，设置源后直接安装，对于配置文件自动写入默认路径

1、设置安装源

To set up the yum repository for RHEL/CentOS, create the file named /etc/yum.repos.d/nginx.repo with the following contents:

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/OS/OSRELEASE/$basearch/
gpgcheck=0
enabled=1
Replace “OS” with “rhel” or “centos”, depending on the distribution used, and “OSRELEASE” with “5”, “6”, or “7”, for 5.x, 6.x, or 7.x versions, respectively.

具体文件内容为：

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1

2、执行以下命令安装

sudo yum install nginx

3、启动、停止nginx服务

sudo nginx
sudo nginx -s stop
