一.压缩功能概述
compression algo
启用http协议中的压缩机制，常用算法有gzip deflate
compression type
要压缩的类型
示例：
compression algo gzip deflate
compression type text/plain text/html text/css text/xml text/javascript application/javascript
二.haproxy未配置压缩功能实战
1>.配置haproxy的配置文件
[root@node102.yinzhengjie.org.cn ~]# cat /etc/haproxy/haproxy.cfg global maxconn 100000 chroot /yinzhengjie/softwares/haproxy stats socket /yinzhengjie/softwares/haproxy/haproxy.sock mode 600 level admin user haproxy group haproxy daemon nbproc 2 cpu-map 1 0 cpu-map 2 1 nbthread 2 pidfile /yinzhengjie/softwares/haproxy/haproxy.pid log 127.0.0.1 local5 info defaults option http-keep-alive option forwardfor option redispatch option abortonclose maxconn 100000 mode http timeout connect 300000ms timeout client 300000ms timeout server 300000ms listen status_page bind 172.30.1.102:8888 stats enable stats uri /haproxy-status stats auth admin:yinzhengjie stats realm "Welcome to the haproxy load balancer status page of YinZhengjie" stats hide-version stats admin if TRUE stats refresh 5s listen WEB_PORT_80 bind 172.30.1.102:80 balance roundrobin cookie HAPROXY-COOKIE insert indirect nocache server web01 172.30.1.106:80 cookie httpd-106 check inter 3000 fall 3 rise 5 server web02 172.30.1.107:80 cookie httpd-107 check inter 3000 fall 3 rise 5 server web03 172.30.1.108:80 cookie httpd-107 check inter 3000 fall 3 rise 5 backup [root@node102.yinzhengjie.org.cn ~]# [root@node102.yinzhengjie.org.cn ~]# systemctl restart haproxy [root@node102.yinzhengjie.org.cn ~]#
2>.浏览器访问haproxy服务器并观察请求报文和响应报文，如下图所示。
三.haproxy配置压缩功能实战
1>.配置haproxy的配置文件
[root@node102.yinzhengjie.org.cn ~]# cat /etc/haproxy/haproxy.cfg global maxconn 100000 chroot /yinzhengjie/softwares/haproxy stats socket /yinzhengjie/softwares/haproxy/haproxy.sock mode 600 level admin user haproxy group haproxy daemon nbproc 2 cpu-map 1 0 cpu-map 2 1 nbthread 2 pidfile /yinzhengjie/softwares/haproxy/haproxy.pid log 127.0.0.1 local5 info defaults option http-keep-alive option forwardfor option redispatch option abortonclose maxconn 100000 mode http timeout connect 300000ms timeout client 300000ms timeout server 300000ms listen status_page bind 172.30.1.102:8888 stats enable stats uri /haproxy-status stats auth admin:yinzhengjie stats realm "Welcome to the haproxy load balancer status page of YinZhengjie" stats hide-version stats admin if TRUE stats refresh 5s listen WEB_PORT_80 bind 172.30.1.102:80 #告诉浏览器支持的压缩算法 compression algo gzip deflate #告诉浏览器支持的压缩类型 compression type text/plain text/html text/css text/xml text/javascript application/javascript balance roundrobin cookie HAPROXY-COOKIE insert indirect nocache server web01 172.30.1.106:80 cookie httpd-106 check inter 3000 fall 3 rise 5 server web02 172.30.1.107:80 cookie httpd-107 check inter 3000 fall 3 rise 5 server web03 172.30.1.108:80 cookie httpd-107 check inter 3000 fall 3 rise 5 backup [root@node102.yinzhengjie.org.cn ~]# [root@node102.yinzhengjie.org.cn ~]# systemctl restart haproxy #别忘记重启使得配置生效。 [root@node102.yinzhengjie.org.cn ~]#
