The process of installing MySQL Community edition 5.6.37

There are many ways to install MySQL, but I like Yum best because it's simple and no brains.

So first #rpm-UVH http://repo.mysql.com/mysql-community-release-el6-5.noarch.rpm, then #yum install Mysql-community-server, for installation, the version of this installation is 5.6 Community Edition.

After installation, it is found that #service mysqld start cannot be started,

This time to check the MySQL error log,#less/var/log/mysqld.log, found that there are such words:

[error] innodb: auto-extending data file ./ibdata1 is of a  different size 640 pages  (ROUNDED DOWN TO MB)  than specified  in the .cnf file: initial 768 pages, max 0  (relevant  If non-zero)  pages!2017-09-01 14:26:55 29830 [error] innodb: could not  open or create the system tablespace. If you tried to  Add new data files to the system tablespace, and it failed  here, you should now edit innodb_data_file_path in my.cnf back  to what it was, and remove the new ibdata files innodb  created in this failed attempt. InnoDB only wrote those  files full of Zeros, but did not yet use them in any way. but be  careful: do not remove old data files which contain your  precious data!2017-09-01 14:26:55 29830 [ERROR] Plugin  ' InnoDB '  init  function returned error.2017-09-01 14:26:55 29830 [ERROR] Plugin  ' InnoDB '  registration as a STORAGE ENGINE failed.2017-09-01 14:26:55  29830 [error] unknown/unsupported storage engine: innodb2017-09-01 14:26:55  29830 [error] aborting

The reason for this error is that the MySQL5.5.8 GA default engine is InnoDB, and the configuration file (MY.CNF) is set to Skip-innodb, there are two ways to encounter this problem, one is in the my.cnf content changed to this:

#loose-skip-innodb default-storage-engine = MyISAM

There is another way to be cruel, is #rm-rf/var/lib/mysql/ib*, Ibdata1, IB_LOGFILE0, ib_logfile1 files removed, and then re- #service mysqld Start a bit,

After you start, you need to #mysql_upgrade ,

Then #mysql_secure_installation, enter the new password for root, and then in the "Remove anonymous users?" [y/n] "This step selects Y, which means to kill all anonymous users.

When all is done,#chkconfig mysqldon, set the boot automatically to start MySQL:

#mysql-V to see if the version is 5.6, so the entire MySQL 5.6 installation is complete, enjoy it.
