HAProxy负载均衡安装

下载安装包

wget  http://download.openpkg.org/components/cache/haproxy/haproxy-2.4.3.tar.gz

安装依赖包

yum -y install make gcc gcc-c++ openssl-devel

开始编译

[root@zabbix-server haproxy-2.4.3]# make TARGET=linux-glibc  PREFIX=/usr/local/haproxy

默认不创建配置文件目录和日志目录，所以创建一下

[root@zabbix-server haproxy-2.4.3]# mkdir -p /usr/local/haproxy/{conf,logs}
[root@zabbix-server haproxy-2.4.3]# ll /usr/local/haproxy/
total 0
drwxr-xr-x 2 root root  6 Sep  5 22:33 conf
drwxr-xr-x 3 root root 21 Sep  5 22:32 doc
drwxr-xr-x 2 root root  6 Sep  5 22:33 logs
drwxr-xr-x 2 root root 21 Sep  5 22:32 sbin
drwxr-xr-x 3 root root 17 Sep  5 22:32 share

由于安装目录没有配置文件，所以将源码包里的示例配置文件复制过去并且重命名为haproxy.cfg

到此，HAProxy安装完成
