Step # 1 : Stop mysql service
# /etc/init.d/mysql stop
Stopping MySQL database server: mysqld.
Step # 2: Start to MySQL server w/o password:
# mysqld_safe --skip-grant-tables &
Output: 5988 Starting mysqld daemon with databases from /var/lib/mysql mysqld_safe: started
Step # 3: Connect to mysql server using mysql client:
# mysql -u root
Output:Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 1 to server version: 4.1.15-Debian_1-log Type 'help;' or '\h' for help. Type '\c' to clear the buffer. mysql>
Step # 4: Setup new MySQL root user password
mysql> use mysql;
mysql> update user set password=PASSWORD("NEW-ROOT-PASSWORD") where User='root';
mysql> flush privileges;
Step # 5: Stop MySQL Server:
Stopping MySQL database server: mysqld STOPPING server from pid file /var/run/mysqld/mysqld.pid mysqld_safe: ended + Done mysqld_safe –skip-grant-tables
# /etc/init.d/mysql stop
Step # 6: Start MySQL server and test it
# /etc/init.d/mysql start
# mysql -u root -p
Allow Slave to connect master:
C:\mysql>create user 'replica'@'192.168.0.110' identified by '<YOUR PASSWORD>';
NOTE: 192.168.0.110 which is the SLAVE machine‟s address.
i. mysql>grant create,insert,select,update,delete on ejbca.* to 'replica'@'192.168.0.110';
Checking if Slave can connect to Master:
C:\>mysql –u replica –h 192.168.0.100 –p
C:\>Enter password: <YOUR VALUES>
NOTE: If the mysql prompt opens then the Master machine can be accessed from the Slave machine.
The easiest and most straightforward method for setting up replication is to use new master and slave servers.
You can also use this method if you are setting up new servers but have an existing dump of the databases from a different server that you want to load into your replication configuration. By loading the data into a new master, the data will be automatically replicated to the slaves.
To set up replication between a new master and slave:
MySQL is the relational database system of choice for open sourcers. Replication is the process of replicating data from one MySQL database server (the master) into another (the slave). We’ll go into why you would want to replicate a MySQL database in another article.
Using the master-slave configuration mentioned above, only the changes made to the master are replicated in the slave. Changes made to the slave do not affect the master.
If you follow the steps below, you can set up MySQL replication in a matter of minutes. Continue reading “MySQL Replication” »
