（1）Nginx安装配置
① 下载Nginx 安装
wget -c http://nginx.org/download/nginx-1.12.0.tar.gz
② 解压安装包
tar -xzf nginx-1.12.0.tar.gz
③ 进入源码目录
cd nginx-1.12.0
④ 进入源码目录，预编译，编译 ，安装
useradd www
./configure --prefix=/usr/local/nginx --user=www --group=www
注释：
如果在编译的过程中，报.configure:error :c complier cc is not found
解决办法是yum install gcc gcc-c++
如果在编译的过程中，报./configure: error: the HTTP rewrite module requires the PCRE library.
解决办法是yum install pcre-devel
如果在编译的过程中，报/configure: error: the HTTP gzip module requires the zlib library.
解决办法是yum install -y zlib-devel
完了，执行make make install
⑤ nginx配置文件组成剖析
nginx配置文件由conf html logs sbin组成
conf目录，存放的是配置文件
html目录，是网站发布目录
logs是日志目录
sbin目录，是存放命令的目录
⑥ 关闭selinux 和防火墙
setenfroce 0 service iptabltes stop
⑦ 启动nginx
/usr/local/nginx/sbin/nginx
⑧ 查看端口和进程是否启动
ps -ef |grep nginx netstat -ntl|grep 80
⑨ 修改nginx发布目录
进入 cd /usr/local/nginx/html
在html目录下，有一个index.html文件，修改它，即可
重启nginx /usr/local/nginx/sbin/nginx -s reload
⑩ 停止nginx /usr/local/nginx/sbin/nginx -s stop
⑪ nginx开机自启动 把需要开机自启动相对内容写到/etc/rc.local配置文件中
⑫ /usr/local/nginx/sbin/nginx -v 查看nginx版本信息
⑬ /usr/local/nginx/sbin/nginx -V 查看nginx参数信息
⑭ nginx虚拟主机的配置
<1>去除nginx.conf配置文件中的#号，空格 grep -v "#" nginx.conf | grep -v "^$">>nginx.conf.swp
<2>打开vim nginx.conf配置文件，找到server配置段
server {
listen 80;
server_name www.jf1.com;
location / {
root html;
index index.html index.htm;
}
}
注释：
<1> server_name 为网站的域名
<2> 网站上的index.html默认存放在html目录根目录下，也可以修改为html /www.jf1.com 在这个目录下创建index,html文件
<3> 有几个网站就配置几个server段
<4> server段配置，也可以从nginx.conf单独出来，在nginx配置文件中，把server段放在vhosts目录下，在http配置段中加入include vhosts/*
⑮ nginx升级
<1> 下载新版本的nginx源码文件，解压，进入源码编译目录，预编译，编译
<2> 备份旧版本的nginx可执行文件 mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.old
<3> cp objs/nginx /usr/local/nginx/sbin
<4> 测试新版本的nginx是否正常
/usr/local/nginx/sbin/nginx -t
<5> 验证nginx升级是否成功
/usr/local/nginx/sbin -V
