OpenSUSE12.2MySQL5.6 database installation and configuration bitsCN.com

Install and configure Open SUSE12.2 MySQL5.6 database

System environment: Open SUSE12.2 x86_64

1. Download "SuSE Linux Enterprise Server 11 (x86, 64-bit), RPM Bundle" or "SuSE Linux Enterprise Server 11 (x86, 64-bit ), RPM Package Client Utilities "," SuSE Linux Enterprise Server 11 (x86, 64-bit), RPM PackageMySQL Server ", address: https://dev.mysql.com/downloads/mysql/

2. because MySQL of MySQL 5.5.25a already exists in the new SUSE 12.2 system installed, we recommend that you clear the installation process after MySQL 5.5.25 is cleared ), however, it can also be overwritten during installation. As described in the MySQL official website documents, if you need to log on locally, you need to install the same fashion MySQL-server and MySQL-client:

Rpm-ivh MySQL-server-5.6.13-1.sles11.x86_64.rpm

Rpm-ivh MySQL-client-5.6.13-1.sles11.x86_64.rpm

3. after the installation is complete, you can find my in the/usr directory. cnf, but my. cnf has nothing to do. configure my below. cnf. This configuration is for reference only.

# Don't listen on a TCP/IP port at all. This can be a security enhancement,
# If all processes that need to connect to mysqld run on the same host.
# All interaction with mysqld must be made via Unix sockets or named pipes.
# Note that using this option without enabling named pipes on Windows
# (Via the "enable-named-pipe" option) will render mysqld useless!

#   #skip-networking  # Replication Master Server (default)  # binary logging is required for replication  log-bin=mysql-bin  # binary logging format - mixed recommended  binlog_format=mixed  ​# required unique id between 1 and 2^32 - 1  # defaults to 1 if master-host is not set  # but will not function as a master if omitted  server-id   = 1  # Replication Slave (comment out master section to use this)  #  # To configure this host as a replication slave, you can choose between  # two methods :  #  # 1) Use the CHANGE MASTER TO command (fully described in our manual) -  #    the syntax is:  #  #    CHANGE MASTER TO MASTER_HOST=
 
  , MASTER_PORT=
  
   ,  #    MASTER_USER=
   
    , MASTER_PASSWORD=
    
      ;  #  #    where you replace 
     
      , 
      
       , 
       
         by quoted strings and # 
        
          by the master's port number (3306 by default). # # Example: # # CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306, # MASTER_USER='joe', MASTER_PASSWORD='secret'; # # OR # 
        
       
      
     
    
   
  
 

#2) Set the variables below. However, in case you choose this method, then
# Start replication for the first time (even unsuccessfully, for example
# If you mistyped the password in master-password and the slave fails
# Connect), the slave will create a master.info file, and any later
# Change in this file to the variables 'values below will be ignored and
# Overridden by the content of the master.info file, unless you shutdown
# The slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (Commented) and instead use change master to (see above)

#  # required unique id between 2 and 2^32 - 1  # (and different from the master)  # defaults to 2 if master-host is set  # but will not function as a slave if omitted  #server-id       = 2  #  # The replication master for this slave - required  #master-host     =   
 
    #  # The username the slave will use for authentication when connecting  # to the master - required  #master-user     =   
  
     #  # The password the slave will authenticate with when connecting to  # the master - required  #master-password =   
   
      #  # The port the master is listening on.  # optional - defaults to 3306  #master-port     =

4. you can see a few different information from the default configuration file.

1. basedir path configuration

2. datadir path configuration

3. [client] socket path configuration

4. [mysqld] socket path configuration

5. [safe_mysqld] socket path configuration

6. [mysqldump] socket path configuration

Because the datadir path is set to "/opt/mysql", you need to copy the entire "mysql" folder under the default path "/var/lib" to "/opt. Note the following: first check the permissions and owner of "mysql" under "/var/lib" and find that the folder owner is mysql. Check the copied "mysql" folder owner under "/opt" and find that the owner is root. if the mysql service is started, the following error occurs: StartingMySQL. the server quit without updating PID file. Modify the "mysql" folder owner in the "/opt" Directory:

/Opt> chown-R mysql: mysql

Note: [client] socket path configuration, [mysqld] socket path configuration, [safe_mysqld] socket path configuration, and [mysqldump] socket path configuration, all are configured under "/opt/mysql. Otherwise, the mysql. sock error is not found.

Start mysql service: service mysql start

View mysql service status: service mysql status

If everything is normal, log in to, change the root password or add a new user using the random root password generated during installation (in '/. mysql_secret.
