Three virtual machines, set up two virtual machines from the master database, a client to do.
Referring to build the master database from step 1 to 3 and a fifth step.
Modify the host officiating: db1 from: db2 client is: mycat
The three virtual machines for domain name resolution:
vi /etc/hosts
192168150100 db1
192168150110 db2
192.168.150.120 mycat
Yum source node configuration to two (vi /etc/yum.repos.d/local.repo follows:
[Centos]
name=centos
baseurl = file: /// opt / CentOS
gpgcheck=0
enabled=1
[yum]
name=yum
baseurl = file: /// opt / gpmall-repo
gpgcheck=0
enabled=1
Clear cache: yum clean all
yum repolist
db1,, db2 .. mariadb two service nodes and restart the service installation:
yum install mariadb-server –y
Systemctl restart mariadb
Installation mycat auxiliary packet node: yum install bash-completion -y
Install java packages: yum install java
Yum install java-1.8.0-openjdk java-1.8.0-openjdk-devel.x86_64 -y
Java -version
Modify db1 node configuration file: vi /etc/my.cnf
[mysql]
server_id=100
log_bin=mysql-bin
binlog-ignore-db=keystone
Db2 modify node configuration file: vi /etc/my.cnf
[mysql]
server_id=110
log_bin=mysql-bin
binlog-ignore-db=keystone
Restart the service: systemctl restart mariadb
Two nodes are operating: mysql_secure_installation (up point y, the password is 000000) to install the database
Here it is: n means:
db1: mysql -uroot -p000000
Access to the database
create user ‘zhao’@’%’ identified by ‘000000’;
grant replication slave on *.* to ‘zhao’@’%’ ;
show master status
db2: mysql -uroot -p000000
change master to master_host=’192.168.150.100’,master_user=’zhao’,master_password=’000000’,master_log_fire=’mysql-bin.000002’,master_log_pos=659;
start slave;
search result
show slave status\G;
Mycat Node: Query java version: Java -version
Extract the package: tar -zxvf Mycat-server-1.6-RELEASE-20161028204710-linux.tar.gz -c / usr / local /
Cd /usr/local/
ls
Chown 777 /usr/local/mycat/
Ll
Chown root /usr/local/mycat/
Chomd 777 mycat/
Chomd 777 mycat/ -R
Ll
Cd conf /
ls
Modify the first configuration file: vi /schema.xml(/usr/local/mycat/conf/schema.xml)
Name = 'testdb' to userdb
Database = 'db $ 0-743' to test
Writehost host=’hostM1’ url=’loalhost:3306’ user=’root’改为Writehost host=’hostM1’ url=’192.168..150.100:3306’ user=’root’
Readhost the url =; 192.168.150.110: 3306 password = '123456'
(Schema.xml modify user permissions: chown root: root / usr / local / conf / schema.xml)
Second: vi server.xml
Delete the last four lines
Instead userdb
/bin/bash /usr/local/mycat/bin/mycat start
Yum install net
Yum install net-tools.x86_64 -y
Netstat -ntlp
There are two ports 8066 and 9066
Verify separate read and write
Installation maeiaDB-client services on a virtual machine mycat
Yum intall –y MariaDB-client
Mysql –uroot –p000000
Show database;
Use USERDB;
Show tables;
Select *from company;
(2) Use MYcat sql command on a virtual machine to add data (2, "basketall", "usa") table company, after completion of adding information table is added
insert into company values(2,”bastetball”,”usa”);
select * from company;
Verify mycat service operation to separate the database to read and write, using the MySQL command by separating the information on the 9066 port query database read and write operations
Mysql –h (mycat ip) –P9066 –uroot –p123456 –e ‘show @@datasource;’
Authorized on any client machine as the root user can log database
Grant all privileges on *.* to root@’%’ identified by “123456”
Creating a user so that the user is connected from node db2 and give from node synchronization master node database permissions
Grant replication slave on *.* to ‘user’@’db2’identified by ‘123456’
