CentOS用yum安装、配置MariaDB

.创建/etc/yum.repos.d/MariaDB.repo文件，这里用到了刚刚发布正式版的10.

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.0/centos6-amd64/
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=
.准备好repo文件后可以使用yum来安装了

# yum install MariaDB-server MariaDB-client
.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
.创建新的数据目录

# mkdir /var/data/db/mariadb
.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        =
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
.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            =
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 =
sort_buffer_size = 1M
read_buffer_size = 1M
read_rnd_buffer_size = 4M
myisam_sort_buffer_size = 64M
thread_cache_size =
query_cache_size= 16M
thread_concurrency =
log-bin=mysql-bin
binlog_format=mixed
server-id   =
.初始化数据

# mysql_install_db --defaults-file=/etc/my.cnf --datadir=/var/data/db/mariadb/ --user=mysql
.启动服务

# service mysql start
.设置ROOT密码

# mysqladmin -u root password ""
.登陆mysql

# mysql -uroot -p
.授权root远程登录

#root可从任何IP登陆，注意修改密码:''
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '' WITH GRANT OPTION;

#root可从指定IP登陆，注意修改密码:''、IP:'192.168.1.188'
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.1.188' IDENTIFIED BY '' WITH GRANT OPTION;
mysql>FLUSH RIVILEGES
