MariaDB數據庫 分為源代碼版本和二進制版本，源代碼版本需要cmake編譯，這里是二進制版本的安裝

# tar zxvf mariadb-5.5.31-linux-x86_64.tar.gz # mv mariadb-5.5.31-linux-x86_64 /usr/local/MySQL （必需這樣，很多腳本或可執行程序都會直接訪問這個目錄）# groupadd mysql 增加 mysql 屬組 # useradd -g mysql mysql 增加 mysql 用戶 并歸于mysql 屬組 # chown mysql:mysql -Rf /usr/local/mysql 設置 mysql 目錄的用戶及用戶組歸屬。 # chmod +x -Rf /usr/local/mysql 賜予可執行權限 # cp /usr/local/mysql/support-files/my-medium.cnf /etc/my.cnf 復制默認mysql配置 文件到/etc 目錄 # /usr/local/mysql/scripts/mysql_install_db --user=mysql 初始化數據 庫 # cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql 復制mysql服務程序 到系統 目錄 # chkconfig mysql on 添加mysql 至系統服務并設置為開機啟動 # service mysql start 啟動mysql#vim /etc/profile 編輯profile,將mysql的可執行路徑加入系統PATHexport PATH=/usr/local/mysql/bin:$PATH #source /etc/profile 使PATH生效。#mysqladmin -u root password 'yourrootpassword' 設定root賬號及密碼#mysql -uroot -p 使用root用戶登錄mysql[none]>use mysql 切換至mysql數據庫。[mysql]>select user,host,password from user; --查看系統權限[mysql]>drop user ''@'localhost'; --刪除不安全的賬戶[mysql]>drop user root@'::1';[mysql]>drop user root@127.0.0.1;

[mysql]>select user,host,password from user; --再次查看系統權限，確保不安全的賬戶均被刪除。

[mysql]>flush privileges; --刷新權限

1）修改字符集為UTF8

#vi /etc/my.cnf

在[client]下面添加 default-character-set = utf8

在[mysqld]下面添加 character_set_server = utf8

修改完重啟：#service mysql restart

2）增加錯誤日志

#vi /etc/my.cnf

在[mysqld]下面添加：

log-error = /usr/local/mysql/log/error.loggeneral-log-file = /usr/local/mysql/log/mysql.log

修改完重啟：#service mysql restart

3) 設置為不區分大小寫，linux下默認會區分大小寫。

#vi /etc/my.cnf

在[mysqld]下面添加：

lower_case_table_name=1

修改完重啟：#service mysql restart

出現 FATAL ERROR: Could not find ./bin/my_print_defaults 解決方法

錯誤信息：

FATALERROR:Couldnotfind./bin/my_print_defaultsIf you are using a binary release, you must run this script fromwithin the directory the archive extracted into. If you compiledMySQL yourself you must run 'make install' first.

或

[root@bogon scripts]# /usr/local/mysql/scripts/mysql_install_db --user=mysql&[1] 16874[root@bogon scripts]#FATAL ERROR: Could not find ./bin/my_print_defaultsIf you compiled from source, you need to run 'make install' tocopy the software into the correct location ready for operation.If you are using a binary release, you must either be at the toplevel of the extracted archive, or pass the --basedir optionpointing to that location.

解決方法：

[root@bogon scripts]# /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data &(這點非常重要)
