linux下mariadb安裝初始化,字符集設定

Linux下安裝Mariadb,我是使用的centos 7.1系統,在yum源配置好的情況下

yum search mariadb

搜尋結果如下

==================================================================================== N/S matched: mariadb =====================================================================================
mariadb-bench.x86_64 : MariaDB benchmark scripts and data
mariadb-devel.i686 : Files for development of MariaDB/MySQL applications
mariadb-devel.x86_64 : Files for development of MariaDB/MySQL applications
mariadb-embedded.i686 : MariaDB as an embeddable library
mariadb-embedded.x86_64 : MariaDB as an embeddable library
mariadb-embedded-devel.i686 : Development files for MariaDB as an embeddable library
mariadb-embedded-devel.x86_64 : Development files for MariaDB as an embeddable library
mariadb-libs.x86_64 : The shared libraries required for MariaDB/MySQL clients
mariadb-libs.i686 : The shared libraries required for MariaDB/MySQL clients
mariadb-server.x86_64 : The MariaDB server and related files
mariadb.x86_64 : A community developed branch of MySQL
mariadb-test.x86_64 : The test suite distributed with MariaD
percona-xtrabackup.x86_64 : Online backup for InnoDB/XtraDB in MySQL, Percona Server and MariaDB
  Name and summary matches only, use "search all" for everything.

然後安裝mariadb-server.x86_64   mariadb.x86_64這兩個包(一個是服務一個是客戶端,不同的系統名字可能不一樣)

yum install mariadb.x86_64

yum install mariadb-server.x86_64

或者 yum groupinstall -y mariadb mariadb-server

或者直接yum install mariadb會直接裝好(我第一次就是直接使用這個命令裝好的)

裝完後啟動mariadb

systemctl start mariadb

先進一下資料庫試一下,沒問題就是安裝完成

接下來就是初始化了

mysql_secure_installation  #這是一個快速初始化的命令

 首先他會提示輸入root密碼

Enter current password for root (enter for none):

初次安裝時沒有密碼的所以直接回車

然後Change the root password? [Y/n]  修改密碼

Remove anonymous users? [Y/n]   移除匿名使用者,這個一般都要移除

Disallow root login remotely? [Y/n]  不允許root使用者遠端登入,一般是不允許,所以yes

Remove test database and access to it? [Y/n]  刪除test資料庫,這個不是太重要

Reload privilege tables now? [Y/n]  是否重新載入授權表  yes

這樣基本初始化就完成了

設定字符集一般建議是在配置檔案中設定,也可以在資料庫中設定,在資料庫中設定的話當服務重啟後就會恢復預設字符集,會出現亂碼現象

配置檔案一般在/etc/my.cnf

vim /etc/my.cnf

[mysqld]下新增如下配置

init_connect='SET collation_connection = utf8_unicode_ci'

init_connect='SET NAMES utf8'

character-set-server=utf8

collation-server=utf8_unicode_ci

skip-character-set-client-handshake

[client]下新增 (有些配置檔案沒有[client],是因為包含了 “!includedir /etc/my.cnf.d”這句話,說明其他配置在這個目錄中)

default-character-set=utf8

然後重啟mariadb

登入資料庫檢視字符集是否設定正確 show variables like "%character%";show variables like "%collation%"

這樣就設定成功了

建立資料庫:

CREATE DATABASE `test2` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci

匯入sql檔案

Source sql檔案路徑
