+## Haproxy way
+HAProxy is a free and open source software written in C language that provides
high availability, load balancing, and application proxy based on TCP and HTTP.
+
+### Install
+1. Download HAProxy
+
+ download link: https://src.fedoraproject.org/repo/pkgs/haproxy/
+
+2. Unzip
+ ```
+ tar -zxvf haproxy-2.6.15.tar.gz -C /opt/

+ ```
+
+3. Compile
+
+ Enter the haproxy directory
+ ```
+ yum install gcc gcc-c++ -y
+
+ make TARGET=linux-glibc PREFIX=/usr/local/haproxy
+
+ make install PREFIX=/usr/local/haproxy
+ ```
+
+### Configuration
+1. Configure the haproxy.conf file
+
+ vim /etc/rsyslog.d/haproxy.conf
+ ```
+ $ModLoad imudp
+ $UDPServerRun 514
+ local0.* /usr/local/haproxy/logs/haproxy.log

+ ```
+
+2. Enable remote logging
+
+ vim /etc/sysconfig/rsyslog
+
+ `SYSLOGD_OPTIONS="-c 2 -r -m 0" `
+
+ Parameter analysis:
+
+ - -c 2 Use compatibility mode, default is -c 5. -r turns on remote logging
+
+ - -m 0 mark timestamp. The unit is minutes. When it is 0, it means the
function is disabled.
+
+3. Make changes effective
+
+ `systemctl restart rsyslog`
+

+ vim /usr/local/haproxy/haproxy.cfg

+ ip:8888/haproxy
+
+ Login password: admin: admin
+
+ Note: The WEB login port, account, and password need to be configured in
the haproxy.cfg file
+
+4. Test whether the port conversion is successful

+## Haproxy 方式
+HAProxy是一个使用C语言编写的自由及开放源代码软件，其提供高可用性、负载均衡，以及基于TCP和HTTP的应用程序代理。
+
+### 安装
+1. 下载 HAProxy
+
+ 下载地址：https://src.fedoraproject.org/repo/pkgs/haproxy/
+
+2. 解压
+ ```
+ tar -zxvf haproxy-2.6.15.tar.gz -C /opt/

+
+ 参数解析：

+
+ make install PREFIX=/usr/local/haproxy
+ ```
+
+### Configuration
+1. Configure the haproxy.conf file
+
+ vim /etc/rsyslog.d/haproxy.conf
+ ```
+ $ModLoad imudp
+ $UDPServerRun 514
+ local0.* /usr/local/haproxy/logs/haproxy.log
+ &~
+ ```

+
+4. Edit load balancing file
+
+ vim /usr/local/haproxy/haproxy.cfg
+
+ ```
