1、下载tar包,可直接服务器在线下载
wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz
2、将mysql安装到/usr/local/mysql下
# 解压
tar -xvf mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz
# 移动
mv mysql-5.7.22-linux-glibc2.12-x86_64 /usr/local/
# 重命名
mv /usr/local/mysql-5.7.22-linux-glibc2.12-x86_64 /usr/local/mysql
3、新建data目录
mkdir /usr/local/mysql/data
4、新建mysql用户、mysql用户组
# mysql用户组
groupadd mysql
# mysql用户
useradd mysql -g mysql
5、将/usr/local/mysql的所有者及所属组改为mysql
chown -R mysql.mysql /usr/local/mysql
6、配置
/usr/local/mysql/bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data
# 编辑/etc/my.cnf
[mysqld] datadir=/usr/local/mysql/data basedir=/usr/local/mysql socket=/tmp/mysql.sock user=mysql port=3306 character-set-server=utf8
# 取消密码验证
skip-grant-tables # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 # skip-grant-tables [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid
7、开启服务
# 将mysql加入服务
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
# 开机自启
chkconfig mysql on
# 开启
service mysql start
8、设置密码
# 登录(由于/etc/my.cnf中设置了取消密码验证,所以此处密码任意)
/usr/local/mysql/bin/mysql -u root -p
# 操作mysql数据库
>>use mysql;
# 修改密码
>>update user set authentication_string=password(‘你的密码‘) where user=‘root‘;
>>flush privileges;
>>exit;
9、将/etc/my.cnf中的skip-grant-tables删除
10、登录再次设置密码(不知道为啥如果不再次设置密码就操作不了数据库了)
/usr/local/mysql/bin/mysql -u root -p
>>ALTER USER ‘root‘@‘localhost‘ IDENTIFIED BY ‘修改后的密码‘;
>>exit;
11、允许远程连接
/usr/local/mysql/bin/mysql -u root -p
>>use mysql;
>>update user set host=‘%‘ where user = ‘root‘;
>>flush privileges;
>>exit;
12、添加快捷方式
ln -s /usr/local/mysql/bin/mysql /usr/bin
