新架构第5天

Q1、rewrite几种规则案例演示区别

[root@Centos7 conf.d]# vim web.conf
server_tokens off;

server {
        listen 192.168.37.87:80;
        listen 192.168.37.87:443 ssl;
        server_name test.magedu.net;
        access_log logs/test.magedu.net.access.log json;
        ssl_certificate /apps/nginx/ssl/magedu.net.crt;
        ssl_certificate_key /apps/nginx/ssl/magedu.net.key;
        ssl_session_cache shared:sslcache:20m;
        ssl_session_timeout 10m;
        location / {
                root /data/site1;
                index index.html;
                if ( $scheme = http ) { 
                        rewrite ^/(.*)$ https://test.magedu.net/$1 permanent;   #http跳转到https
                }
                if ( !-f $request_filename ) {
                        rewrite .* http://test.magedu.net/index.html;       #输入错误地址跳转到主页
                }
        }
        location /last {
                rewrite ^/last/(.*)$ /info/$1 last;     #访问last目录会跳转到info目录
                return 888 "last";
        }
}
[root@Centos7 conf.d]# nginx -s reload
[root@Centos7 conf.d]# mkdir /data/site1/{last,info}
[root@Centos7 conf.d]# echo infomation > /data/site1/info/index.html
[root@Centos7 conf.d]# chown nginx.nginx -R /data/site1/

#客户端测试
[root@centos6 ~]$ curl test.magedu.net      #跳转到https



301 Moved Permanently
nginx


[root@centos6 ~]$ curl -kL test.magedu.net
test

[root@centos6 ~]$ curl -kL test.magedu.net/1234412      #错误页面跳转到主页
test
[root@centos6 ~]$ curl -kL test.magedu.net/last/index.html  #访问last跳转到info
infomation

Q2、使用proxy反向代理后端多台web服务器

[root@Centos7 conf.d]# vim web.conf
server_tokens off;

upstream local {
        server 192.168.37.67;
        server 192.168.37.77;
        server 127.0.0.1:9001 backup;
}

server {
        listen 80;
        server_name test.magedu.net;
        location / {
                proxy_pass http://local;
        }
}

server {
        listen 127.0.0.1:9001;
        root /data/site2;
        index index.html;
        access_log logs/test.magedeu.net.sorry.log;
}
[root@Centos7 conf.d]# echo sorry > /data/site2/index.html

#客户端测试
[root@centos6 ~]$ while :;do curl test.magedu.net;sleep 0.5;done
