### 下载Nginx源码包
nginx下载站点：`http://nginx.org/en/download.html`，目前稳定版是`nginx-1.14.0`，我们下载源码包：
~~~
http://nginx.org/download/nginx-1.14.0.tar.gz
~~~
下载并解包：
~~~
[root@localhost packages]# wget http://nginx.org/download/nginx-1.14.0.tar.gz
[root@localhost packages]# tar zxf nginx-1.14.0.tar.gz
[root@localhost packages]# cd nginx-1.14.0
~~~
添加用户和组
~~~
[root@localhost nginx-1.14.0]# groupadd nginx
[root@localhost nginx-1.14.0]# useradd -g nginx nginx
~~~
依赖包安装：
Nginx的依赖包有：PCRE，zlib，OpenSSL。这些包我们在安装PHP时已经安装过了，所以不需要再安装了。
创建目录：
创建编译参数中用到的目录`/var/tmp/nginx/client/`，否则安装完nginx后启动会报该目录不存在。
~~~
[root@localhost nginx-1.14.0]# mkdir -p /var/tmp/nginx/client/
~~~
开始安装：
~~~
[root@localhost nginx-1.14.0]# ./configure --prefix=/usr/local/nginx --sbin-path=/usr/local/nginx/sbin/nginx --conf-path=/usr/local/nginx/conf/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/lock/nginx.lock --user=nginx --group=nginx --with-http_ssl_module --with-http_stub_status_module --with-http_gzip_static_module --http-client-body-temp-path=/var/tmp/nginx/client/ --http-proxy-temp-path=/var/tmp/nginx/proxy/ --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi --http-scgi-temp-path=/var/tmp/nginx/scgi --with-pcre
[root@localhost nginx-1.14.0]# make
[root@localhost nginx-1.14.0]# make install
~~~
安装完成，执行`nginx -V`检查是否安装成功
~~~
[root@localhost nginx-1.14.0]# /usr/local/nginx/sbin/nginx -V
~~~
结果如下：
:-: 
检查Nginx环境及配置：
~~~
[root@localhost nginx-1.14.0]# /usr/local/nginx/sbin/nginx -t
~~~
结果如下：
:-: 
配置nginx服务：
创建`/etc/init.d/nginx`文件
~~~
[root@localhost nginx-1.14.0]# vim /etc/init.d/nginx
~~~
文件内容如下：
~~~
#!/bin/sh

创建日志目录：
~~~
[root@localhost nginx-1.14.0]# mkdir /usr/local/nginx/logs
[root@localhost nginx-1.14.0]# chown -R www.www /usr/local/nginx/logs
~~~
加入服务：
~~~
[root@localhost nginx-1.14.0]# chmod a+wrx /etc/init.d/nginx
[root@localhost nginx-1.14.0]# chkconfig --add nginx
[root@localhost nginx-1.14.0]# chkconfig nginx on
~~~
启动服务：
~~~
[root@localhost nginx-1.14.0]# service nginx start
[root@localhost nginx-1.14.0]# service nginx status
~~~
:-: 
关闭防火墙：
~~~
[root@localhost nginx-1.14.0]# systemctl stop firewalld.service #停止firewall
[root@localhost nginx-1.14.0]# systemctl disable firewalld.service #禁止firewall开机启动
~~~
关闭SELINUX：
~~~
[root@localhost nginx-1.14.0]# vi /etc/selinux/config
#SELINUX=enforcing #注释掉
#SELINUXTYPE=targeted #注释掉
SELINUX=disabled #增加
:wq! #保存退出
setenforce 0 #使配置立即生效
~~~
安装iptables防火墙：
~~~
[root@localhost nginx-1.14.0]# yum install iptables-services #安装
[root@localhost nginx-1.14.0]# vi /etc/sysconfig/iptables #编辑防火墙配置文件
# sample configuration for iptables service
# you can edit this manually or use system-config-firewall
# please do not ask us to add additional ports/services to this default configuration

systemctl enable iptables.service #设置防火墙开机启动
/usr/libexec/iptables/iptables.init restart #重启防火墙

测试访问：
通过ip访问服务器
:-: 
Nginx安装完成。关闭虚拟机，拍个快照吧
配置虚拟主机
编辑`/usr/local/nginx/conf/nginx.conf`，在最后的花括号“}”上一行增加一行：`include vhost/*.conf;`，保存。
创建目录vhost：
~~~
[root@localhost nginx-1.14.0]# mkdir /usr/loca/nginx/conf/vhost
~~~
在vhost目录下创建虚拟主机配置文件即可，扩展名为`.conf`，内容为：
~~~
server {
listen 80;
server_name www.abc.com;
location / {
root /data/www/abc/public;
index index.php index.html index.htm;
}
}
~~~
