1、安装mysql
wgethttps://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz#下载mysql
tarzxvfmysql-5.7.22-linux-glibc2.12-x86_64.tar.gz#解压mysql文件
cpmysql-5.7.22-linux-glibc2.12-x86_64/usr/local/mysql-r#复制解压后的mysql目录到系统的本地软件目录
groupaddmysql#创建mysql组
useraddmysql-gmysql#创建mysql用户并添加到mysql用户组
pwd#当前目录/usr/local/mysql
chown-Rmysql.#修改mysql所属用户
chgrp-Rmysql.#修改mysql所属组
cd/usr/local/mysql/bin
yuminstalllibaio
./mysqld--user=mysql--basedir=/usr/local/mysql--datadir=/ddhome/bin/mysql/data#data目录没有就创建(用mysql用户)，另外mysql_install_db这个命令已经废了换成了mysqld
ln-s/usr/local/mysql/bin/mysql/usr/bin/mysql#创建mysql快捷方式
servicemysqlstart#启动mysql服务
servicemysqlstop#停止mysql服务
servicemysqlrestart#重启mysql服务
netstat-anp|grepmysqld#查看mysql服务
mysql_install_db--user=mysql--basedir=/usr/local/mysql/--datadir=/ddhome/bin/mysql/data
2、接下来就是登陆了
因为是首次登陆，这里笔者使用的方式是
cat/root/.mysql_secret#这个是root首次登陆mysql的初始密码
mysql-uroot-p密码
SETPASSWORDFOR'root'@'localhost'=PASSWORD('dd@2018');#修改数据密码
GRANTALLPRIVILEGESON*.*TOroot@localhostIDENTIFIEDBY"dd@2018";
3、设置远程客户端登陆
mysql>GRANTALLPRIVILEGESON*.*TO'root'@'192.168.0.0'IDENTIFIEDBY'123456'WITHGRANTOPTION;
mysql>FLUSHPRIVILEGES;
