CentOS6下Haproxy的安装配置

Haproxy 是一个开源的负载均衡和反向代理软件，其提供了高可用的网络服务。其一般是应用于web服务，但同时也能为SMTP和终端服务等提供可靠的支持。

1、下载安装haproxy

wget ftp://195.220.108.108/linux/centos/6.8/os/x86_64/Packages/haproxy-1.5.4-3.el6.x86_64.rpm   --下载
rpm -ivh haproxy-1.5.-.el6.x86_64.rpm   -安装

2、配置Haproxy

cp /etc/haproxy/haproxy.cfg /etc/haproxy/haproxy.cfg.bak
vi /etc/haproxy/haproxy.cfg

-c：Only checks config file and exits with code 0 if no error was found, or exits with code 1 if a syntax error was found.
/usr/local/haproxy/sbin/haproxy -c -f /etc/haproxy/haproxy.cfg  检查配置文件
Configuration file is valid

/etc/haproxy/haproxy.cfg文件

假若想访问监控界面：配置stats uri  /haproxy项，重启服务：

设置防火墙：

iptables -I INPUT -p tcp --dport  -j ACCEPT
service iptables save
service iptables restart 

监控界面：

3、开机启动

chkconfig haproxy on
service haproxy start
或
/usr/local/haproxy/sbin/haproxy -f /etc/haproxy/haproxy.cfg

编译安装haproxy开启支持SSL
