1 前言

一个问题，一篇文章，一出故事。
笔者今天需要实现HAProxy代理sftp，因此整理此文。

2 最佳实践

2.1 实践环境

HAProxy集群环境，

如何使用HAProxy配置PostFix集群？

GlusterFS服务环境，

如何管理GlusterFS的分散卷？

2.2 配置代理

2.2.1 修改配置文件

vim /etc/haproxy/conf.d/gluster.cmdschool.org_24007_glusterd.cfg

加入如下配置，

frontend glusterfs
    bind *:24007
    mode tcp
    timeout client 1m
    log global
    default_backend glusterfs_servers

backend glusterfs_servers
    mode tcp
    log global
    timeout server 1m
    timeout connect 5s
    balance roundrobin
    server gfs01 10.168.0.211:24007 check
    server gfs02 10.168.0.212:24007 check
    server gfs03 10.168.0.213:24007 check
    server gfs04 10.168.0.214:24007 check
    server gfs05 10.168.0.215:24007 check

2.2.2 检查配置

haproxy -c -f /etc/haproxy/conf.d

2.2.3 应用配置

systemctl reload haproxy.service
systemctl status haproxy.service

2.3 客户端挂载

mount -t glusterfs gluster.cmdschool.org:/volume1 /mnt
