几个简单使用nginx的例子---一代

前言：本人主攻后端，简单了解运维，如有错误，请您指正

安装nginx所需依赖
yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel
解压nginx 在/usr/src目录会解压到/usr/local中
tar –xvf pcre-8.37.tar.gz
编译
./configure
make && make install...

存放在/usr/local/nginx/sbin中
./nginx -v 
./nginx
./nginx -s stop
./nginx -s reload

nginx.conf 在/usr/local/nginx/conf目录中
效果:访问 47.101.33.159:80 转发到47.101.33.159:8080
修改server即可
 server {
        listen       80;#
        server_name  47.101.33.159;#

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   html;
            proxy_pass http://47.101.33.159:8080;#
            index  index.html index.htm;
        }
效果:访问47.101.33.159:9000/mydir/mine.html 转发到47.101.33.159:8081/mydir/mine.html
访问了在tomcat下webappmydir中的文件
添加一个server
server {
        listen       9000;
        server_name  47.101.33.159;

        location ~ /mydir/ {
              proxy_pass http://47.101.33.159:8081;

        }

效果:访问47.101.33.159:80/mydrir/mine.html,第一次访问8080，第二次访问8081，轮转
upstream myserver {
        server 101.43.85.67:8080;
        server 101.43.85.67:8081;
}
 server {
        listen       80;
        server_name  101.43.85.67;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   html;
            proxy_pass http://myserver;
            index  index.html index.htm;
        }

效果：静态资源不通过tomcat进行访问，直接映射
访问http://101.43.85.67/image/wechat.jpg 该图片地址为/mydata/image/wechat.jpg
  server {
        listen       80;
        server_name  101.43.85.67;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location /www/ {
            root   /mydata/;
            index  index.html index.htm;
        }
        location /image/ {
           root    /mydata/;
           autoindex    on;
        }
