CenOS7下Haproxy1.7.8负载均衡搭建

女爷i 2022-05-16 03:14 201阅读 0赞

1.首先放置jar包（源代码haproxy-1.7.8.tar.gz）

目录 /usr/local/haproxy

### 2.解压目录         ###

tar -xvf haproxy-1.7.8.tar.gz

进入 haproxy-1.7.8

编译

make TARGET=linux2628 PREFIX=/usr/local/haproxy（需安装gcc不然会报错,目录需存在）

Make install PREFIX=/usr/local/haproxy

![70][]

### 3.编译目录 ###

将haproxy-start.sh放入sbin文件夹中

![70 1][]

创建 conf文件夹，将配置文件放入其中

![70 2][]

创建logs文件夹

![70 3][]

覆盖 /etc/rsyslog.conf（rsyslog需安装）

### 4.运行haproxy-start.sh ###

查看是否已经在运行

![70 4][]

完成后删除源码文件

操作系统一样的话

只需要编译，剩下可以复制编译后的程序目录到相应位置，不需要再一台台编译

### 附录： ###
