Brief introduction to Simple deployment of mariadb and binary packages

MySQL was originally developed by Michael Widenius, and Sun was acquired by Oracle shortly after Mr. Michael sold MySQL to Sun for $1 billion. In Oracle acquisition Mr. Michael is worried that MySQL will have a closed-source risk in the future, a new project named after his daughter Maria's name--mariadb,mariadb the default storage engine is Maria, not MyISAM. Maria can support transactions, but transaction support is not turned on by default because transactional support has a performance impact. You can convert to the Maria engine that supports transactions by using the following statement. ALTER TABLE ' tablename ' Engine=maria transactional=1; As a branch of MySQL it is fully compatible with MySQL everything even improved on the basis of MySQL, If migrating from MySQL to mariadb is very simple, the compatibility points for both are as follows:

1. Data and table definition files (. frm) are binary compatible

2. All client APIs, protocols, and structures are fully consistent

3, all the file name, binary, path, port, etc. are consistent

4. All MySQL connectors, such as PHP, Perl, Python, Java,. NET, MyODBC, Ruby, and MySQL C connector, remain the same in mariadb, which means there is no need to make big changes to existing code

5, Mysql-client package in the MARIADB server can also run normally

6. The Shared client library is binary compatible with MySQL

So migrating data from MySQL to mariadb is relatively simple, for this mariadb simple deployment installation, first to MARIADB official website https:// Downloads.mariadb.org find the latest stable version, of course, this time for rapid deployment of the direct use of binary package deployment

So mariadb initial deployment installation is over, in short, and MySQL is the same, previously said MySQL security and password settings, including adding system startup script my.cnf file These can, need to see, here do not do too much to repeat the HTTP/s jim123.blog.51cto.com/4763600/1870863, http://jim123.blog.51cto.com/4763600/1864671,/http jim123.blog.51cto.com/4763600/1843243
