使用vagrant快速搭建MariaDB Galera Cluster集群测试环境

参考

下载并安装ubuntu 12.04的32位box 初始化vagrant box

wget http://files.vagrantup.com/precise32.box
vagrant box add base Downloads/precise32.box
vagrant init

设置最大内存512

vim ~/VagrantFile

config.vm.provider :virtualbox do |vb|
    # Don't boot with headless mode
    vb.gui = false

    # Use VBoxManage to customize the VM. For example to change memory:
    vb.customize ["modifyvm", :id, "--memory", "512"]
end

配置虚拟IP

config.vm.network :private_network, ip: "10.0.1.100"

启动虚拟机修改为163源

启动虚拟机，并通过ssh登录到客户机

vagrant up
vagrant ssh

采用163.com的源

sudo vim /etc/apt/sources.list

更新源

sudo aptitude update

添加mariadb源，并安装集群版

大部分linux的二进制发行包都可以在这里找到：https://downloads.mariadb.org/mariadb/repositories/

apt-get install python-software-properties
sudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xcbcb082a1bb943db
sudo add-apt-repository 'deb http://mirrors.tuna.tsinghua.edu.cn/mariadb/repo/5.5/ubuntu precise main'
sudo aptitude update
sudo aptitude install mariadb-galera-server mariadb-client

打包虚拟机，以便再次安装 退出客户机，回到主机界面

vargrant package --output galera-db.box
vargant box add db galera-db.box

配置虚拟机

vim ~/Vagrantfile

Vagrant.configure("2") do |config|
  config.vm.provision "shell", inline: "echo Hello"
  config.vm.define "db1" do |db1|
    db1.vm.box = "db"
    db1.vm.network :private_network, ip: "10.0.1.100"
  end

  config.vm.define "db2" do |db2|
    db2.vm.box = "db"
    db2.vm.network :private_network, ip: "10.0.1.101"
  end
end

重新加载虚拟机配置

vagrant reload

配置第一台db节点

vagrant ssh db1
sudo service mysql start
sudo mysql_secure_installation mysql -uroot -p

mysql> GRANT USAGE ON *.* to sst@'%' IDENTIFIED BY 'sstpass123';
mysql> GRANT ALL PRIVILEGES on *.* to sst@'%';
mysql> FLUSH PRIVILEGES;
mysql> quit

sudo cp /usr/share/mysql/wsrep.cnf /etc/mysql/conf.d/ sudo vim /etc/mysql/conf.d/wsrep.cnf

wsrep_provider=/usr/lib/galera/libgalera_smm.so
wsrep_cluster_address="gcomm://"
wsrep_sst_auth=sst:sstpass123
wsrep_sst_method=rsync
wsrep_node_name=db1
wsrep_node_address=10.0.1.100

sudo service mysql restart

安装第二个节点

vagrant ssh db2

除了wsrep.cnf有少许不同外，其他同第一节点

wsrep_cluster_address="gcomm://10.0.1.100"
wsrep_node_name=db2
wsrep_node_address=10.0.1.101

sudo service mysql restart

测试节点同步

mysql -usst -psstpass123 -h10.0.1.100 show status like 'wsrep%'; 可以看到wsrep_connected都为ON

create database testdb;
use testdb;
create table t(id int primary key auto_increment);
insert into t values(null);
insert into t values(null);
select * from t;
exit;

mysql -usst -psstpass123 -h10.0.1.101

use testdb;
select * from t;
insert into t values(null);
insert into t values(null);
select * from t;
