部署haproxy

director一、director2：

安裝haproxy：

wget http://pkgs.fedoraproject.org/repo/pkgs/haproxy/haproxy-1.6.9.tar.gz/c52eee40eb66f290d6f089c339b9d2b3/haproxy-1.6.9.tar.gz
tar zxf haproxy-1.6.9.tar.gz -C /usr/local/
cd /usr/local/haproxy-1.6.9
make TARGET=linux2628 ARCH=x86_64 PREFIX=/usr/local/haproxy
make install PREFIX=/usr/local/haproxy

修改配置文件：
vim /usr/local/haproxy/haproxy.cfg

啓動
/usr/local/haproxy/sbin/haproxy -f /usr/local/haproxy/haproxy.cfg
重啓
/usr/local/haproxy/sbin/haproxy -f /usr/local/haproxy/haproxy.cfg -st `cat /usr/local/haproxy/haproxy.pid`
中止
killall haproxy

將haproxy加入到系統服務中。腳本內容以下
