CentOS用yum安装、配置MariaDB
摘要: 相比源码安装,用yum安装MariaDB更加简单快捷,而且可以在线更新升级,推荐使用!
1.创建/etc/yum.repos.d/MariaDB.repo文件,这里用到了刚刚发布正式版的10.0
[mariadb] name = MariaDB baseurl = http://yum.mariadb.org/10.0/centos6-amd64/ gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=1
2.准备好repo文件后可以使用yum来安装了
# yum install MariaDB-server MariaDB-client
3.我喜欢自定义数据目录和服务端口,所以移除默认的数据目录
# rm -rf /var/lib/mysql
4.创建新的数据目录
# mkdir /var/data/db/mariadb
5.修改配置文件/etc/my.cnf.d/mysql-clients.cnf,重点是[client],其他的可以参考
[client] port = 3307 socket = /var/data/db/mariadb/mysql.sock [mysql] no-auto-rehash [mysqldump] quick max_allowed_packet = 64M [myisamchk] key_buffer_size = 128M sort_buffer_size = 128M read_buffer = 2M write_buffer = 2M [mysqlhotcopy] interactive-timeout
6.修改配置文件/etc/my.cnf.d/server.cnf,这里的性能参数来自my-large.ini文件
[mysqld] port = 3307 datadir = /var/data/db/mariadb socket = /var/data/db/mariadb/mysql.sock skip-external-locking key_buffer_size = 256M max_allowed_packet = 64M table_open_cache = 256 sort_buffer_size = 1M read_buffer_size = 1M read_rnd_buffer_size = 4M myisam_sort_buffer_size = 64M thread_cache_size = 8 query_cache_size= 16M thread_concurrency = 8 log-bin=mysql-bin binlog_format=mixed server-id = 1
7.初始化数据
# mysql_install_db --defaults-file=/etc/my.cnf --datadir=/var/data/db/mariadb/ --user=mysql
8.启动服务
# service mysql start
9.设置ROOT密码
# mysqladmin -u root password "8888888"
10.登陆mysql
# mysql -uroot -p
11.授权root远程登录
#root可从任何IP登陆,注意修改密码:'888888' mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '888888' WITH GRANT OPTION; #root可从指定IP登陆,注意修改密码:'888888'、IP:'192.168.1.188' mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.1.188' IDENTIFIED BY '888888' WITH GRANT OPTION; mysql>FLUSH RIVILEGES
