安装nginx
yum -y install nginx
测试是否安装正确：
nginx -t
打印如下：
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf test is successful
CentOS7.0+ nginx实现停止、启动、重启
systemctl stop nginx.service;
systemctl start nginx.service;
systemctl restart nginx.service;
systemctl status nginx.service;
开机自启：
systemctl enable nginx.service
取消开机自启：
systemctl disable nginx.service
nginx配置的修改：
修改nginx.conf（位置在/etc/nginx/）文件，可将配置文件放在一个文件夹中，让nginx自己去读取自定义的配置文件，修改结果如下
# For more information on configuration, see:
# * Official English Documentation: http://nginx.org/en/docs/
# * Official Russian Documentation: http://nginx.org/ru/docs/
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
# Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;
events {
worker_connections 1024;
}
http {
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
include /etc/nginx/mime.types;
default_type application/octet-stream;
# Load modular configuration files from the /etc/nginx/conf.d directory.
# See http://nginx.org/en/docs/ngx_core_module.html#include
# for more information.
include /etc/nginx/conf.d/*.conf;
}
include /etc/nginx/conf.d/*.conf;这一句的意思是从/etc/nginx/conf.d/文件夹中搜索所有*.conf的配置文件填充进配置中，例如我发布了一个网站，端口号是5000，如果不进行nginx映射，只能在linux的内网中进行访问，
无法在外网进行访问
例如我在/etc/nginx/conf.d/中添加了myblog.conf，如下面，重启nginx后，80端口的http请求都会转向到内部的5000端口，这样自己的网站就可以访问了
server {
listen 80;
location / {
proxy_pass http://localhost:5000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection keep-alive;
proxy_set_header Host $host;
proxy_cache_bypass $http_ipgrade;
}
}
