haproxy小结(三)配置示例
在haproxy小结(二)配置文件篇 中对 haproxy.conf中所涉及的主要参数做一个解析。本篇列举一些现网中使用的真实示例。
一、http服务器配置示例
#--------------------------------------------------------------------- # Global settings # code by www.361way.com #--------------------------------------------------------------------- global # to have these messages end up in /var/log/haproxy.log you will # need to: # # 1) configure syslog to accept network log events. This is done # by adding the '-r' option to the SYSLOGD_OPTIONS in # /etc/sysconfig/syslog # # 2) configure local2 events to go to the /var/log/haproxy.log # file. A line like the following can be added to # /etc/sysconfig/syslog # # local2.* /var/log/haproxy.log # log 127.0.0.1 local2 chroot /var/lib/haproxy pidfile /var/run/haproxy.pid maxconn 4000 user haproxy group haproxy daemon defaults mode http log global option httplog option dontlognull option http-server-close option forwardfor except 127.0.0.0/8 option redispatch retries 3 timeout http-request 10s timeout queue 1m timeout connect 10s timeout client 1m timeout server 1m timeout http-keep-alive 10s timeout check 10s maxconn 30000 listen stats mode http bind 0.0.0.0:1080 stats enable stats hide-version stats uri /haproxyadmin?stats stats realm Haproxy\ Statistics stats auth admin:admin stats admin if TRUE frontend http-in bind *:80 mode http log global option httpclose option logasap option dontlognull capture request header Host len 20 capture request header Referer len 60 default_backend servers frontend healthcheck bind :1099 mode http option httpclose option forwardfor default_backend servers backend servers balance roundrobin server websrv1 192.168.10.11:80 check maxconn 2000 server websrv2 192.168.10.12:80 check maxconn 2000
二、MySQL服务器配置示例
global 、defaults、listen部分同上面http配置部分相同,forntend与backend部分配置如下:
# code from www.361way.com frontend mysql bind *:3306 mode tcp log global default_backend mysqlservers backend mysqlservers balance leastconn server dbsrv1 192.168.10.11:3306 check port 3306 intval 2 rise 1 fall 2 maxconn 300 server dbsrv2 192.168.10.12:3306 check port 3306 intval 2 rise 1 fall 2 maxconn 300
三、动静分离配置示例
# code from www.361way.com global log 127.0.0.1 local2 chroot /var/lib/haproxy pidfile /var/run/haproxy.pid maxconn 4000 user haproxy group haproxy daemon # turn on stats unix socket stats socket /var/lib/haproxy/stats defaults mode http log global option httplog option dontlognull option http-server-close option forwardfor except 127.0.0.0/8 option redispatch retries 3 timeout http-request 10s timeout queue 1m timeout connect 10s timeout client 1m timeout server 1m timeout http-keep-alive 10s timeout check 10s maxconn 30000 listen stats mode http bind 0.0.0.0:1080 stats enable stats hide-version stats uri /haproxyadmin?stats stats realm Haproxy\ Statistics stats auth admin:admin stats admin if TRUE frontend http-in bind *:80 mode http log global option httpclose option logasap option dontlognull capture request header Host len 20 capture request header Referer len 60 acl url_static path_beg -i /static /images /javascript /stylesheets acl url_static path_end -i .jpg .jpeg .gif .png .css .js use_backend static_servers if url_static default_backend dynamic_servers backend static_servers balance roundrobin server imgsrv1 172.16.200.7:80 check maxconn 6000 server imgsrv2 172.16.200.8:80 check maxconn 6000 backend dynamic_servers cookie srv insert nocache balance roundrobin server websrv1 172.16.200.7:80 check maxconn 1000 cookie websrv1 server websrv2 172.16.200.8:80 check maxconn 1000 cookie websrv2 server websrv3 172.16.200.9:80 check maxconn 1000 cookie websrv3
