linux上安装mysql5.7

[mysqld]
datadir=/usr/local/mysql/data
basedir=/usr/local/mysql
socket=/tmp/mysql.sock
user=mysql
port=3306
character-set-server=utf8<br># 取消密码验证<br>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;

>>eixt;

12、添加快捷方式

ln -s /usr/local/mysql/bin/mysql /usr/bin
