下载地址：http://download.chinaunix.net/download/0013000/12508.shtml  可以在这里下载，[root@localhost ~]# yum -y install cmake  gcc gcc-c++  autoconf automake zlib*  libxml* \ncurses ncurses-devel libtool-ltdl-devel* make  bison bison-devel libaio [root@localhost ~]# tar zxvf haproxy-1.4.25.tar.gz [root@localhost ~]# cd haproxy-1.4.25[root@localhost haproxy-1.4.25]#

开始编译安装

（MAKE 参数请参考文件中的README）

[root@localhost haproxy-1.4.25]# make TARGET=linux26 PREFIX=/usr/local/haproxy[root@localhost haproxy-1.4.25]# make install PREFIX=/usr/local/haproxy[root@localhost haproxy-1.4.25]# install -d /usr/local/sbin[root@localhost haproxy-1.4.25]# install haproxy /usr/local/sbin[root@localhost haproxy-1.4.25]# install -d /usr/local/share/man/man1[root@localhost haproxy-1.4.25]# install -m 644 doc/haproxy.1 /usr/local/share/man/man1[root@localhost haproxy-1.4.25]# install -d /usr/local/doc/haproxy[root@localhost haproxy-1.4.25]# for x in configuration architecture haproxy-en haproxy-fr; do \> install -m 644 doc/$x.txt /usr/local/doc/haproxy ; \> done[root@localhost haproxy-1.4.25]#

安装完成，

我们检测一下是否安装成功

[root@localhost haproxy-1.4.25]# haproxy -vHA-Proxy version 1.4.25 2014/03/27Copyright 2000-2014 Willy Tarreau <w@1wt.eu>

则安装成功

配置haproxy.cfg文件
这里解释一下，我用的时候安装文件夹用 /root/haproxy-1.4.25/examples/haproxy.cfg 这个是自带的配置文件

[root@localhost examples]# vim haproxy.cfg# this config needs haproxy-1.1.28 or haproxy-1.2.1global        log 127.0.0.1   local0        log 127.0.0.1   local1 notice        #log loghost    local0 info        maxconn 4096#       chroot /usr/share/haproxy        chroot  /usr/local/haproxy        uid 99        gid 99        daemon        #debug        #quietdefaults        log     global        mode    http        option  httplog        option  dontlognull        retries 3        #redispatch        maxconn 2000        contimeout      5000        clitimeout      50000        srvtimeout      50000#============================这一段是我后面加上去了。 就是WEB代理listen web_proxy        bind *:80        mode    http        option httpchk GET /index.html        server s1 192.168.11.210:80 weight 3 check        server s2 192.168.11.211:80 weight 3 check#后面的我做的注释#listen appli1-rewrite 0.0.0.0:10001#       cookie  SERVERID rewrite#       balance roundrobin#       server  app1_1 192.168.34.23:8080 cookie app1inst1 check inter 2000 rise 2 fall 5#       server  app1_2 192.168.34.32:8080 cookie app1inst2 check inter 2000 rise 2 fall 5#       server  app1_3 192.168.34.27:8080 cookie app1inst3 check inter 2000 rise 2 fall 5#       server  app1_4 192.168.34.42:8080 cookie app1inst4 check inter 2000 rise 2 fall 5##listen appli2-insert 0.0.0.0:10002#       option  httpchk#       balance roundrobin#       cookie  SERVERID insert indirect nocache#       server  inst1 192.168.114.56:80 cookie server01 check inter 2000 fall 3#       server  inst2 192.168.114.56:81 cookie server02 check inter 2000 fall 3#       capture cookie vgnvisitor= len 32##       option  httpclose               # disable keep-alive#       rspidel ^Set-cookie:\ IP=       # do not let this cookie tell our internal IP address#       #listen appli3-relais 0.0.0.0:10003#       dispatch 192.168.135.17:80##listen appli4-backup 0.0.0.0:10004#       option  httpchk /index.html#       option  persist#       balance roundrobin#       server  inst1 192.168.114.56:80 check inter 2000 fall 3#       server  inst2 192.168.114.56:81 check inter 2000 fall 3 backup##listen ssl-relay 0.0.0.0:8443#       option  ssl-hello-chk#       balance source#       server  inst1 192.168.110.56:443 check inter 2000 fall 3#       server  inst2 192.168.110.57:443 check inter 2000 fall 3#       server  back1 192.168.120.58:443 backup#listen appli5-backup 0.0.0.0:10005#       option  httpchk *#       balance roundrobin#       cookie  SERVERID insert indirect nocache#       server  inst1 192.168.114.56:80 cookie server01 check inter 2000 fall 3#       server  inst2 192.168.114.56:81 cookie server02 check inter 2000 fall 3#       server  inst3 192.168.114.57:80 backup check inter 2000 fall 3#       capture cookie ASPSESSION len 32#       srvtimeout      20000#       option  httpclose               # disable keep-alive#       option  checkcache              # block response if set-cookie & cacheable#       rspidel ^Set-cookie:\ IP=       # do not let this cookie tell our internal IP address#       errorloc        502     http://192.168.114.58/error502.html#       errorfile       503     /etc/haproxy/errors/503.http

启动服务

[root@localhost examples]# haproxy -f /root/haproxy-1.4.25/examples/haproxy.cfg [WARNING] 316/220055 (2376) : parsing [/root/haproxy-1.4.25/examples/haproxy.cfg:22]: keyword 'redispatch' is deprecated, please use 'option redispatch' instead.[ALERT] 316/220055 (2376) : [haproxy.main()] Cannot chroot(/usr/local/sbin/haproxy).

出现的报错信息，下面我们来解决问题。因为上面配置文件是我改后的，应该没有什么问题。

[ALERT] 316/220055 (2376) : [haproxy.main()] Cannot chroot(/usr/local/sbin/haproxy).

是配置文件chroot的目录不对，根据我的文档安装改成 chroot /urs/local/haproxy 就可以解决了执行 mkdir /usr/share/haproxy

[WARNING] 316/220055 (2376) : parsing [/root/haproxy-1.4.25/examples/haproxy.cfg:22]: keyword 'redispatch' is deprecated, please use 'option redispatch' instead.

这个报错信息是配置文件22行的问题，我是做了注释掉就可以起动服务了。注释到相对应的错误行

再次起动服务：

[root@localhost examples]# haproxy -f /root/haproxy-1.4.25/examples/haproxy.cfg [root@localhost examples]#

没有任何提示，那我们检测一下是否启动成功

看一下进程信息

[root@localhost examples]# ps -ef |grep haproxynobody    3826     1  0 22:38 ?        00:00:00 haproxy -f /root/haproxy-1.4.25/examples/haproxy.cfgroot      3837  1260  0 22:38 pts/0    00:00:00 grep haproxy

进程已经在

看一下端口信息

下图就成功了80端口是我们自定义的服务。最后加的配置文件

[root@localhost examples]# netstat -anp |grep haproxytcp        0      0 0.0.0.0:80                  0.0.0.0:*                   LISTEN      3826/haproxy        udp        0      0 0.0.0.0:43549               0.0.0.0:*                               3826/haproxy

把配置文件移动到/etc目录下

[root@localhost examples]# cd /etc/[root@localhost etc]# 复制haproxy配置文件到/etc/目录下面[root@localhost etc]# cp /root/haproxy-1.4.25/examples/haproxy.cfg haproxy.cfg我们再一次查看进程 kill掉。 在用/etc/haproxy.cfg的配置文件启动看看[root@localhost etc]# ps -ef | grep haproxynobody    3826     1  0 22:38 ?        00:00:00 haproxy -f /root/haproxy-1.4.25/examples/haproxy.cfgroot      3901  1260  0 22:40 pts/0    00:00:00 grep haproxy[root@localhost etc]# kill 3826[root@localhost etc]# ps -ef | grep haproxyroot      3928  1260  0 22:41 pts/0    00:00:00 grep haproxy已经kill掉进程，进程已经没有在运行了， 我们现在用/etc/haproxy.cfg 来运行服务[root@localhost etc]# haproxy -f /etc/haproxy.cfg[root@localhost etc]# ps -ef |grep haproxy.cfgnobody    3959     1  0 22:42 ?        00:00:00 haproxy -f /etc/haproxy.cfgroot      3965  1260  0 22:43 pts/0    00:00:00 grep haproxy.cfg

我们已经看到运行成功

设置以服务形式启动

目录切换到/etc/init.d

这段是参考：http://blog.chinaunix.net/uid-24250828-id-3778032.html

重起服务haproxy

[root@localhost init.d]# service haproxy restartenv: /etc/init.d/haproxy: Permission denied这个提示。大概是权限问题。我们下面加上执行权限[root@localhost init.d]# ll haproxy -rw-r--r--. 1 root root 2588 Nov 13 23:02 haproxy[root@localhost init.d]# chmod -R 655 haproxy [root@localhost init.d]# ll haproxy -rw-r-xr-x. 1 root root 2588 Nov 13 23:02 haproxy选 看一下进程是否存在，不存在我们重起haproxy服务[root@localhost init.d]# ps -ef | grep haproxyroot      7409  1260  0 23:56 pts/0    00:00:00 grep haproxy[root@localhost init.d]# service haproxy restartStopping haproxy:                                          [FAILED]Starting haproxy:                                          [  OK  ][root@localhost init.d]# ps -ef | grep haproxynobody    7444     1  0 23:56 ?        00:00:00 /usr/local/haproxy/sbin/haproxy -D -f /etc/haproxy.cfg -p /var/run/haproxy.pidroot      7449  1260  0 23:56 pts/0    00:00:00 grep haproxy[root@localhost init.d]# 配置上面就完成了
