一、准备阶段
1、5台机器
10.1.2.180 作为mysql机器
10.1.2.200-202作为集群节点
10.1.2.203作为nginx反向代理
2、拓扑图
三、mogilefs集群部署步聚
1、180机器
1.1由于前面单节，180机器安装了mysql和Mogilefs，而现在180作为单独Mysql机器，所以先停掉Mogilefs服务
|
1
2
|
[root@logicserver tmp]# /etc/init.d/mogilefsd stop
Stopping mogilefsd [确定]
|
1.2创建mysql用户root的密码，方便集群节点连接上去
|
1
2
|
MariaDB [mogilefs]> GRANT ALL ON *.* TO
'root'
@
'10.1.%.%'
IDENTIFIED BY
'168'
;
|
|
1
2
|
MariaDB [mogilefs]> flush privileges;
Query OK,
0
rows affected (
0.04
sec)
|
2、200机器
2.1 重新初始化数据库
|
1
|
[root@xenserver1 mogdata]# mogdbsetup --dbhost=
10.1
.
2.180
--dbname=mogilefs --dbport=
3306
--dbrootuser=root --dbrootpass=
168
--dbuser=moguser --dbpass=mog168
|
2.2修改配置文件

root@xenserver1 mogdata]# vim /etc/mogilefs/mogilefsd.conf
db_dsn = DBI:mysql:mogilefs:host=

.
2.180
db_user = moguser
db_pass = mog168
listen =
0.0
.
0.0
:
7001
|
2.3重启服务
|

|
[root@xenserver1 mogdata]# service mogilefsd restart
|
|

|
[root@xenserver1 mogdata]# ss -tnl | sed -n

|
2.4启动 mogstored服务

四、203机器上nginx部署
1、下载地址
http://nginx.org/en/download.html
http://www.grid.net.ru/nginx/mogilefs.en.html
2、
