CentOS用yum安裝 配置MariaDB

1.建立/etc/yum.repos.d/mariadb.repo檔案，這裡用到了剛剛發布正式版的10.0

[mariadb]

name = mariadb
baseurl = 
gpgkey=
gpgcheck=1

2.準備好repo檔案後可以使用yum來安裝了

# yum install mariadb-server mariadb-client

3.我喜歡自定義資料目錄和服務埠，所以移除預設的資料目錄

# rm -rf /var/lib/mysql

4.建立新的資料目錄

# mkdir /var/data/db/mariadb

5.修改配置檔案/etc/my.cnf.d/mysql-clients.cnf，重點是[client]，其他的可以參考

[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.修改配置檔案/etc/my.cnf.d/server.cnf，這裡的效能引數來自my-large.ini檔案

[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.初始化資料

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

8.啟動服務

# service mysql start

9.設定root密碼

# mysqladmin -u root password "8888888"

10.登陸mysql

# mysql -uroot -p

11.授權root遠端登入

#root可從任何ip登陸，注意修改密碼:'888888' 

mysql>grant all privileges on *.* to 'root'@'%' identified by '888888' with grant option;
#root可從指定ip登陸，注意修改密碼:'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
