haproxy羣集服務搭建

---------------------安裝服務軟件包----------------

yum install pcre-devel bzip2-devel gcc gcc-c++ -y

tar zxvf haproxy-1.5.19.tar.gz -C /opt

cd /opt/haproxy-1.5.19/

make TARGET=linux26

make install

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

mkdir /etc/haproxy

cp /opt/haproxy-1.5.19/examples/haproxy.cfg /etc/haproxy/

vim /etc/haproxy/haproxy.cfg

# chroot /usr/share/haproxy               //禁錮share目錄

# redispatch //反覆從新發送

----------刪除全部listen，增長下段---------

listen webcluster 0.0.0.0:80           //容許任意網絡訪問網站

option httpchk GET /index.html          //定義默認首頁類型

balance roundrobin                    //負載均衡算法，輪詢

server inst1 192.168.218.130:80 check inter 2000 fall 3                  //定義在線節點 

server inst2 192.168.218.131:80 check inter 2000 fall 3

--------------------建立啓動鏈接，開啓服務----------------------

cp /opt/haproxy-1.5.19/examples/haproxy.init /etc/init.d/haproxy

chmod 755 /etc/init.d/haproxy 

chkconfig --add haproxy                   //開機自啓

ln -s /usr/local/sbin/haproxy /usr/sbin/haproxy

systemctl start haproxy.service

systemctl stop firewalld.service

setenforce 0
