haproxy—TCP负载均衡

1.下载haproxy最新版本 http://www.haproxy.org/download/1.5/src/haproxy-1.5.12.tar.gz

2.haproxy的安装

mkdir –p /usr/local/haproxy/logs/ 也就是创建这个文件夹/usr/local/haproxy/logs/

make TARGET=linux26 PREFIX=/usr/local/haproxy make install PREFIX=/usr/local/haproxy

3.执行下面的命令

[root@Template-Redhat54 haproxy-1.4.20]# install -d /usr/local/sbin

[root@Template-Redhat54 haproxy-1.4.20]# install haproxy /usr/local/sbin

[root@Template-Redhat54 haproxy-1.4.20]# install -d /usr/local/share/man/man1

[root@Template-Redhat54 haproxy-1.4.20]# install -m 644 doc/haproxy.1 /usr/local/share/man/man1

[root@Template-Redhat54 haproxy-1.4.20]# install -d /usr/local/doc/haproxy

[root@Template-Redhat54 haproxy-1.4.20]# for x in configuration architecture haproxy-en haproxy-fr; do \ > install -m 644 doc/$x.txt /usr/local/doc/haproxy ; \ > done

4.检查安装结果：

[root@Template-Redhat54 haproxy-1.4.20]# haproxy

看到类似下面的内容证明安装好了

HA-Proxy version 1.4.20 2012/03/10

Copyright 2000-2012 Willy Tarreau <w@1wt.eu>

Usage : haproxy [-f <cfgfile>]* [ -vdVD ] [ -n <maxconn> ] [ -N <maxpconn> ] [ -p <pidfile> ] [ -m <max megs> ]

-v displays version ; -vv shows known build options. -d enters debug mode ; -db only disables background mode.

-V enters verbose mode (disables quiet mode) -D goes daemon -q quiet mode : don't display messages

-c check mode : only check config files and exit -n sets the maximum total# of connections (2000) -m limits the usable amount of memory (in MB)

-N sets the default, per-proxy maximum # of connections (2000) -p writes pids of all children to this file

-de disables epoll() usage even when available -ds disables speculative epoll() usage even when available -dp disables poll() usage even when available

-sf/-st [pid ]* finishes/terminates old pids. Must be last arguments.

5.拷贝haproxy.cfg文件到usr/local/haproxy下。

haproxy.cfg内容如下：
