MySQL

RHEL下

1. 安装mariadb

shell> sudo yum install mariadb* -y

2.rpm安装指定版本的mysql

shell>  wget https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-community-server-8.0.11-1.el7.x86_64.rpm https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-community-client-8.0.11-1.el7.x86_64.rpm https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-community-devel-8.0.11-1.el7.x86_64.rpm https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-community-libs-8.0.11-1.el7.x86_64.rpm https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-community-common-8.0.11-1.el7.x86_64.rpm
shell>  sudo yum install -y wget perl libaio net-tools openssl* numactl
shell>  sudo rpm -ivh mysql-community-common-8.0.11-1.el7.x86_64.rpm mysql-community-libs-8.0.11-1.el7.x86_64.rpm mysql-community-client-8.0.11-1.el7.x86_64.rpm mysql-community-server-8.0.11-1.el7.x86_64.rpm

mysql8

shell>  systemctl status mysqld
shell>  mysqld --initialize --user=mysql
shell>  systemctl start mysqld
shell>  grep "A temporary password" /var/log/mysqld.log
shell>  mysql -uroot -p
mysql> alter user user() identified with mysql_native_password by "123456";
mysql> create user 'messiah'@'%' identified with mysql_native_password by '123456';
mysql> alter user 'root'@'localhost' identified with mysql_native_password by '123456';
mysql> flush privileges;

mysql7-

shell>  sudo rpm -ivh mysql-community-common-5.7.16-1.el7.x86_64.rpm mysql-community-libs-5.7.16-1.el7.x86_64.rpm mysql-community-client-5.7.16-1.el7.x86_64.rpm mysql-community-server-5.7.16-1.el7.x86_64.rpm  mysql-community-devel-5.7.16-1.el7.x86_64.rpm
shell>  cp /usr/share/mysql/my-default.cnf  /etc/my.cnf
#shell>  /usr/bin/mysql_install_db
# mysql_install_db is deprecated.
shell>  mysqld --initialize --user=mysql
shell>  systemctl status mysqld
shell>  grep "A temporary password" /var/log/mysqld.log
shell>  more /root/.mysql_secret
shell> mysql -uroot -p
mysql>  set password = password('123456');

4.开启3306端口

shell> firewall-cmd --list-ports
shell> firewall-cmd --add-port=3306/tcp  --permanent
shell> firewall-cmd --reload #加载新配置

5.启动/停止/重启/自启/关闭/状态 mysql 服务

shell> systemctl start/restart/stop/enable/disable/status mariadb.service/mysqld

REHL6

shell> service mariadb.service status/start/restart/stop

6.配置mysql

/etc/my.cnf
event_scheduler=ON

7.进入mysql服务器

shell> mysql -uroot

1.创建用户

mysql> create user 'messiah'@'%' identified by '123456';
mysql> grant all on *.* to 'messiah'@'%';
授grant option权限
mysql> grant  grant option  on *.* to 'messiah'@'%';
mysql> grant all on *.* to 'messiah'@'%' WITH GRANT OPTION;
mysql> GRANT ALL PRIVILEGES ON *.* TO 'messiah'@'%' IDENTIFIED BY PASSWORD '*6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9' WITH GRANT OPTION
mysql> update mysql.user set user='anonymous' where user = '';
mysql> flush privileges;

Mysql 竖列显示结果

select * from mysql.user \G

mysql报错which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
SQL_mode设置

mysql> SELECT @@GLOBAL.sql_mode;
mysql> SELECT @@sql_mode;
mysql> SET sql_mode = '';
mysql> SET GLOBAL sql_mode = '';

Mysql 事件计划配置

mysql> SHOW VARIABLES LIKE 'event_scheduler';
mysql> SELECT @@event_scheduler;
mysql> SET GLOBAL event_scheduler = 1;
mysql> SET GLOBAL event_scheduler = ON;
