前言

• CentOS 7
• MySQL 5.6
• 查找mysql源 http://repo.mysql.com

步驟

1，添加mysql源

rpm -ivh http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm

注：卸載mysql源 rpm -e --nodeps mysql-community-release-el7-5.noarch
2，安裝mysql

yum install mysql-server

3，啟動mysql

systemctl start mysql

4，查看mysql是否啟動

netstat -tlnp | grep mysql ps -ef | grep mysql

5，初次設置root賬戶密碼

mysqladmin -u root password root

6，進入mysql

mysql -uroot -proot show databases; use mysql; show tables; quit;

7，設置mysql數據編碼格式為utf8。

設置： vi /etc/my.cnf ----------------------------- [mysqld] character_set_server=utf8查看設置結果： mysql> SHOW VARIABLES WHERE Variable_name LIKE 'character\_set\_%' OR Variable_name LIKE 'collation%';+--------------------------+-----------------+ | Variable_name | Value | +--------------------------+-----------------+ | character_set_client | utf8 | | character_set_connection | utf8 | | character_set_database | utf8 | | character_set_filesystem | binary | | character_set_results | utf8 | | character_set_server | utf8 | | character_set_system | utf8 | | collation_connection | utf8_general_ci | | collation_database | utf8_general_ci | | collation_server | utf8_general_ci | +--------------------------+-----------------+ 10 rows in set (0.01 sec)

其它

啟動mysql：systemctl start mysql / systemctl start mysqld
停止mysql：systemctl stop mysql / systemctl stop mysqld
重啟mysql：systemctl restart mysql / systemctl restart mysqld
查看mysql狀態：systemctl status mysql / systemctl status mysqld

mysql服務開啟：systemctl enable mysqld
mysql服務關閉：systemctl disable mysqld
查看mysql服務是否開啟：systemctl list-unit-files|grep mysqld

查看mysql版本：mysql -V
my.cnf配置文件查找順序：mysqld --help --verbose 2> /dev/null | grep -A1 ‘Default options’
