一、安装 adam@hnn:~$ uname -a Linux hnn 3.2.0-35-generic-pae #55-Ubuntu SMP Wed Dec 5 18:04:39 UTC 2012 i686 i686 i386 GNU/Linux wget http://haproxy.1wt.eu/download/1.4/src/haproxy-1.4.22.tar.gz tar xvf haproxy-1.4.22.tar.gz cd haproxy-1.4.22 make TARGET=linux32 PREFIX=/home/adam/haproxy make install PREFIX=/home/adam/haproxy 安装apache sudo apt-get install apache2 二、基本配置 vi /home/adam/haproxy/haproxy.cfg global daemon maxconn 256 log 127.0.0.1 local2 defaults log global mode http timeout connect 5000ms timeout client 50000ms timeout server 50000ms frontend http-in bind *:80 option httplog option httpclose log global default_backend servers backend servers server server2 192.168.0.130 maxconn 32 server server1 192.168.0.129 maxconn 32 listen stats :8888 stats enable stats uri /admin stats auth adam:1234 三、日志配置 sudo vi /etc/rsyslog.d/50-default.conf 增加以下一行 local2.* /var/log/haproxy.log sudo vi /etc/rsyslog.conf 找到下面两行，把注释去掉 #$ModLoad imudp #$UDPServerRun 514 重启rsyslog服务 sudo service rsyslog restart 四、测试并查看日志文件 ab -n 10 -c 20 http://192.168.0.128/index.html 查看haproxy的日志 cat /var/log/haproxy.log Dec 23 20:44:53 localhost haproxy[2628]: 192.168.0.129:60587 [23/Dec/2012:20:44:53.229] http-in servers/server1 1/0/7/5/21 200 478 – - —- 9/9/9/4/0 0/0 “GET /index.html HTTP/1.0″ Dec 23 20:44:53 localhost haproxy[2628]: 192.168.0.129:60589 [23/Dec/2012:20:44:53.229] http-in servers/server1 1/0/7/3/21 200 478 – - —- 8/8/8/3/0 0/0 “GET /index.html HTTP/1.0″ Dec 23 20:44:53 localhost haproxy[2628]: 192.168.0.129:60581 [23/Dec/2012:20:44:53.229] http-in servers/server1 1/0/7/13/28 200 478 – - —- 7/7/7/2/0 0/0 “GET /index.html HTTP/1.0″ Dec 23 20:44:53 localhost haproxy[2628]: 192.168.0.129:60582 [23/Dec/2012:20:44:53.229] http-in servers/server2 1/0/7/13/28 200 478 – - —- 6/6/6/4/0 0/0 “GET /index.html HTTP/1.0″ Dec 23 20:44:53 localhost haproxy[2628]: 192.168.0.129:60583 [23/Dec/2012:20:44:53.229] http-in servers/server1 1/0/7/13/28 200 478 – - —- 5/5/5/1/0 0/0 “GET /index.html HTTP/1.0″ Dec 23 20:44:53 localhost haproxy[2628]: 192.168.0.129:60584 [23/Dec/2012:20:44:53.229] http-in servers/server2 1/0/7/13/28 200 478 – - —- 4/4/4/3/0 0/0 “GET /index.html HTTP/1.0″ Dec 23 20:44:53 localhost haproxy[2628]: 192.168.0.129:60585 [23/Dec/2012:20:44:53.229] http-in servers/server1 1/0/7/13/28 200 478 – - —- 3/3/3/0/0 0/0 “GET /index.html HTTP/1.0″ Dec 23 20:44:53 localhost haproxy[2628]: 192.168.0.129:60586 [23/Dec/2012:20:44:53.229] http-in servers/server2 1/0/7/13/28 200 478 – - —- 2/2/2/2/0 0/0 “GET /index.html HTTP/1.0″ Dec 23 20:44:53 localhost haproxy[2628]: 192.168.0.129:60588 [23/Dec/2012:20:44:53.229] http-in servers/server2 1/0/7/13/28 200 478 – - —- 1/1/1/1/0 0/0 “GET /index.html HTTP/1.0″ Dec 23 20:44:53 localhost haproxy[2628]: 192.168.0.129:60590 [23/Dec/2012:20:44:53.229] http-in servers/server2 1/0/20/5/32 200 478 – - —- 0/0/0/0/0 0/0 “GET /index.html HTTP/1.0″ 查看apache的日志 cat /var/log/apache2/ 192.168.0.128 – - [23/Dec/2012:20:44:52 +0800] “GET /index.html HTTP/1.0″ 200 478 “-” “ApacheBench/2.3″ 192.168.0.128 – - [23/Dec/2012:20:44:52 +0800] “GET /index.html HTTP/1.0″ 200 478 “-” “ApacheBench/2.3″ 192.168.0.128 – - [23/Dec/2012:20:44:52 +0800] “GET /index.html HTTP/1.0″ 200 478 “-” “ApacheBench/2.3″ 192.168.0.128 – - [23/Dec/2012:20:44:52 +0800] “GET /index.html HTTP/1.0″ 200 478 “-” “ApacheBench/2.3″ 五、2013-04-30，在redhat安装注意事项 日志配置：/etc/sysconfig/syslog ，把 SYSLOGD_OPTIONS=”-m 0″ 改为 SYSLOGD_OPTIONS=”-m 0 -r” 另外web server使用HTTP 1.1访问时，必须增加配置项: option httpclose，否则在日志中可以看到Haproxy只在创建新的TCP连接的时候转发请求。 2013-05-06补充，http 1.0默认是一个http请求对应一个tcp连接，除非http heaer中有Connection: Keepalive。而http 1.1默认tcp请求不会主动关闭，除非http header中有Connection: Close。 (责任编辑：IT) |
