[研究] MariaDB Galera Cluster 5.5.34 資料庫安裝(yum) (CentOS 6.5 x64)
2014-01-11
2016-02-17 修訂官方網站和下載網址變更
瑪利亞資料庫 (Maria) 是 MySQL 創辦人離開 Sun 後又開的公司所開發的資料庫系統，很多操作和觀念和原來的 MySQL 相同。

安裝 MariaDB Cluster Server
[root@localhost ~]# yum -y install MariaDB-Galera-server MariaDB-client galera
啟動
[root@centos1 ~]# service mysql start
Starting MySQL.. [ OK ]
[root@centos1 ~]#
設定 reboot 後仍啟動
[root@centos1 ~]# chkconfig mysql on
設定 MariaDB 管理員 root 的密碼 (假設設定為 ABCDE )
[root@centos1 ~]# /usr/bin/mysqladmin -u root password 'ABCDE'
或 (-h 是指定主機名稱)
[root@centos1 ~]# /usr/bin/mysqladmin' -u root -h centos1 password 'ABCDE'
或 (交談方式，除了密碼設定，其他都按下 Enter)
[root@centos1 ~]# /usr/bin/mysql_secure_installation
/usr/bin/mysql_secure_installation: line 379: find_mysql_client: command not found
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n]
New password: (輸入密碼)
Re-enter new password: (輸入密碼)
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n]
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n]
... Success!
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n]
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n]
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!

[root@centos1 ~]#
[root@centos1 ~]# cp /usr/share/mysql/wsrep.cnf /etc/my.cnf.d/
[root@centos1 ~]# vi /etc/my.cnf.d/wsrep.cnf
只需要修改如下4行:
wsrep_provider=/usr/lib64/galera/libgalera_smm.so
wsrep_cluster_address="gcomm://"
wsrep_sst_auth=galerauser:123456
wsrep_sst_method=rsync

cp /usr/share/mysql/wsrep.cnf /etc/my.cnf.d/
sed -i -e "s@wsrep_provider=@#wsrep_provider=@" /etc/my.cnf.d/wsrep.cnf
sed -i -e "/wsrep_provider=/awsrep_provider=/usr/lib64/galera/libgalera_smm.so" /etc/my.cnf.d/wsrep.cnf

cat /etc/my.cnf.d/wsrep.cnf | grep wsrep_sst_method=
重新啟動 MariaDB，讓 wsrep.cnf 生效
[root@centos1 ~]# service mysql restart
Shutting down MySQL. SUCCESS!
Starting MySQL.... SUCCESS!

[root@centos1 ~]#
注意 wsrep_ready 是 ON，wsrep_cluster_size 目前是 1
驗證 port 傾聽狀態
[root@centos1 ~]# netstat -tulpn | grep -e 4567 -e 3306
tcp 0 0 0.0.0.0:4567 0.0.0.0:* LISTEN 4019/mysqld

[root@centos1 ~]#
目前 centos1, centos2, centos3 基本工作測試 OK。
*********************************************************************************
修改 centos2, centos3 的 wsrep.cnf，準備讓 centos2, centos3 都和 centos1 同 Cluster
也就如果 centos2, centos3 出了意外離開 Cluster 後，再次加入 Cluster 時候會以 centos1 資料為準做同步
[root@centos1 ~]# vi /etc/my.cnf.d/wsrep.cnf
只需要修改
wsrep_cluster_address="gcomm://"
為
wsrep_cluster_address="gcomm://192.168.128.101"
或用下面方式修改
sed -i -e "s@wsrep_cluster_address=@#wsrep_cluster_address=@" /etc/my.cnf.d/wsrep.cnf
sed -i -e "/wsrep_cluster_address=/awsrep_cluster_address=\"gcomm://192.168.128.101\"" /etc/my.cnf.d/wsrep.cnf
#驗證
cat /etc/my.cnf.d/wsrep.cnf | grep wsrep_cluster_address=
重新啟動 MariaDB，讓 wsrep.cnf 生效
[root@centos1 ~]# service mysql restart
隨便一台檢查 wsrep_cluster_size ，應該是 3
[root@centos1 ~]# mysql -e "SHOW STATUS LIKE 'wsrep_%'; " -pABCDE | grep wsrep_cluster_size
wsrep_cluster_size 3
[root@centos1 ~]#
隨便一台檢查 wsrep_incoming_addresses ，發現 cluster 中包含 3 台電腦
[root@centos2 ~]# mysql -e "SHOW STATUS LIKE 'wsrep_%'; " -pABCDE | grep wsrep_incoming_addresses
wsrep_incoming_addresses 192.168.128.103:3306,192.168.128.102:3306,192.168.128.101:3306
[root@centos2 ~]#
*********************************************************************************
如果 centos1 掛了呢？
修改 centos1 的 wsrep.cnf，如果 centos1 出了意外離開 Cluster 後，再次加入 Cluster 時候會以 centos2 資料為準做同步，回復資料
[root@centos1 ~]# vi /etc/my.cnf.d/wsrep.cnf
只需要修改
wsrep_cluster_address="gcomm://"
為
wsrep_cluster_address="gcomm://192.168.128.102"
或用下面方式修改
sed -i -e "s@wsrep_cluster_address=@#wsrep_cluster_address=@" /etc/my.cnf.d/wsrep.cnf
sed -i -e "/wsrep_cluster_address=/awsrep_cluster_address=\"gcomm://192.168.128.102\"" /etc/my.cnf.d/wsrep.cnf
#驗證
cat /etc/my.cnf.d/wsrep.cnf | grep wsrep_cluster_address=
重新啟動 MariaDB，讓 wsrep.cnf 生效
[root@centos1 ~]# service mysql restart

發現 http://yum.mariadb.org/5.5/centos6-amd64 提供的 MariaDB 版本為 5.5.40，在 CentOS 6.5 x64 上 yum 安裝後， service mysql restart 會失敗，待研究
