01-MySQL Linux安装
一、检查当前系统是否安装过mysql
rpm -qa|grep mysql 或 ps -ef|grep mysql
二、安装mysql服务端
rpm -ivh MySQL-server-5.5.48-1.linux2.6.i386.rpm
CentOS安装mysql*.rpm提示conflicts with file from package的解决办法
根据安装提示设置密码
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER ! To do so, start the server, then issue the following commands: /usr/bin/mysqladmin -u root password 'new-password' /usr/bin/mysqladmin -u root -h hadoop102 password '123456'
三、安装mysql客户端
rpm -ivh MySQL-client-5.5.48-1.linux2.6.i386.rpm
四、查看mysql安装时创建的用户和组
cat /etc/passwd|grep mysql cat /etc/group|grep mysql mysqladmin --version
五、mysql服务的启动、停止
service mysql start service mysql stop
六、设置mysql服务开机自启动
chkconfig mysql on chkconfig --list | grep mysql ntsysv --看到[*]mysql这一行,表示开机后会自动启动mysql
七、查看mysql安装路径
ps -ef|grep mysql
八、启停相关脚本
/etc/init.d/mysql
九、修改默认配置文件
cp /usr/share/mysql/my-huge.cnf /etc/my.cnf
十、查看、修改字符集
show variables like 'character%' ; [client] default-character-set=utf8 [mysqld] character-set-server=utf8 collation-server=utf8_general_ci [mysql] default-character-set=utf8
