haproxy群集服务搭建

---------------------安装服务软件包----------------

yum install pcre-devel bzip2-devel gcc gcc-c++ -ytar zxvf haproxy-1.5.19.tar.gz -C /optcd /opt/haproxy-1.5.19/make TARGET=linux26make install

----------------------------修改配置文件-------------

mkdir /etc/haproxycp /opt/haproxy-1.5.19/examples/haproxy.cfg /etc/haproxy/vim /etc/haproxy/haproxy.cfg

# chroot /usr/share/haproxy //禁锢share目录

# redispatch //反复重新发送

----------删除所有listen，增加下段---------

listen webcluster 0.0.0.0:80           //允许任意网络访问网站option httpchk GET /index.html          //定义默认首页类型balance roundrobin                    //负载均衡算法，轮询server inst1 192.168.218.130:80 check inter 2000 fall 3                  //定义在线节点 server inst2 192.168.218.131:80 check inter 2000 fall 3

--------------------创建启动连接，开启服务----------------------
