通过yum安装nginx
1. 把 nginx的 包路径信息添加到 /etc/yum.repos.d/nginx.repo:
[root@localhost yum.repos.d]# pwd
/etc/yum.repos.d
[root@localhost yum.repos.d]# ls
CentOS-Base.repo CentOS-Debuginfo.repo CentOS-fasttrack.repo CentOS-Sources.repo nginx.repo
CentOS-CR.repo CentOS-Debuginfo.repo.org CentOS-Media.repo CentOS-Vault.repo
[root@localhost yum.repos.d]# cat nginx.repo
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/x86_64/
gpgcheck=0
enabled=1
2:yum install nginx -y
[root@localhost ~]# yum install nginx -y
Note:如果需要设置代理，
[root@localhost download]# export http_proxy="http://[proxyip]:[port]"；yum install nginx -y
已加载插件：fastestmirror, langpacks

正在安装 : 1:nginx-1.10.1-1.el7.ngx.x86_64
Thanks for using nginx!
Please find the official documentation for nginx here:
* http://nginx.org/en/docs/
Commercial subscriptions for nginx are available on:
* http://nginx.com/products/
----------------------------------------------------------------------
验证中 : 1:nginx-1.10.1-1.el7.ngx.x86_64 1/1
已安装:
nginx.x86_64 1:1.10.1-1.el7.ngx
完毕！
3.修改端口( 修改成8009，默认为80)
[root@localhost conf.d]# pwd
/etc/nginx/conf.d
[root@localhost conf.d]# vi default.conf
4. 启动nginx: service nginx start
安装完成，下面直接就可以启动Nginx了：
service nginx start
(其它相关命令：service nginx start/stop)
5. 从虚拟机访问查看是否已启动成功
curl -i localhost:8009
result is like: "welcome to nginx **** thank you for using nginx "
===> nginx已启动成功
6. 设置从windows主机访问：
a) 打开IE，输入 192.168.1.111:8009 ， 无法访问
b) 返回虚拟机，防火墙设置
[root@localhost init.d]# firewall-cmd --query-port=8009/tcp
no
[root@localhost init.d]# firewall-cmd --add-port=8009/tcp
success
c) 返回IE, 输入 192.168.1.111:8009,现在可以了
Welcome to nginx!
If you see this page, the nginx web server is successfully installed and
working. Further configuration is required.

Thank you for using nginx.
永久停掉防火墙：
[root@localhost yum.repos.d]# service firewalld stop
Redirecting to /bin/systemctl stop firewalld.service
[root@localhost yum.repos.d]# systemctl disable firewalld.service
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
2.测试nginx处理静态文件：
在firefox输入： http://192.168.1.113/media/xdd/22.mp3
一刚开始无法正常播放，需要做几点设置：
1） 查找配置文件目录， 为 /etc/nginx/nginx.conf
[root@localhost nginx]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
2) 修改“user nginx;”==>"user root;" in /etc/nginx/nginx.conf
3) 修改 /etc/nginx/conf.d/default.conf:
#location / {
# root /usr/share/nginx/html;
# index index.html index.htm;
#}
location /media/ {
root /root/myweb/;
#alias /root/myweb/media/;
autoindex on;
#index 22.mp3;
}
4.修改SElinux: 关闭selinux服务
[root@localhost ~]# vi /etc/selinux/config
#SELINUX=enforcing 改为 SELINUX=disabled
note:修改配置文件必须 重启系统 才能生效：
/usr/sbin/sestatus -v|grep -i SELINUX 可以查看状态。
[root@localhost xdd]# setenforce 0 （临时设置生效）
