chown -R mysql:mysql mysql5.7

4.初始化数据和指定安装目录和数据目录

./bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql5.7/ --datadir=/usr/local/mysql5.7/data/

6复制启动文件

cp mysql.server /etc/init.d/mysqld

chmod +x /etc/init.d/mysqld

7.修改启动路径

vi /etc/init.d/mysqld

basedir= /usr/local/mysql5.7

datadir= /usr/local/mysql5.7/data

8.增加环境变量 （最下面添加）l

vi /etc/profile

export MYSQL_HOME=" /usr/local/mysql5.7"

export PATH="$PATH:$MYSQL_HOME/bin"

9.刷新配置文件

source /etc/profile

修改配置文件

vi /etc/my.cnf

[client]

port=3306

[mysqld]

basedir=/usr/local/mysql5.7

datadir=/usr/local/mysql5.7/data

#socket=/usr/local/mysql5.7/mysql.sock

socket=/tmp/mysql.sock

user=mysql

#skip-grant-tables

# Disabling symbolic-links is recommended to prevent assorted security risks

symbolic-links=0

# Settings user and group are ignored when systemd is used.

# If you need to run mysqld under a different user or group,

# customize your systemd unit file for mariadb according to the

# instructions in http://fedoraproject.org/wiki/Systemd

[mysqld_safe]

log-error=/usr/local/mysql5.7/log/mysqld.log

pid-file=/usr/local/mysql5.7/data/mysqld.pid

#

# include all files from the config directory

#

!includedir /etc/my.cnf.d

11.添加开启自启

chkconfig --add mysqld

chkconfig mysqld on

12.启动mysqld

service mysqld start

netstat -anpt

13.修改密码（密码初始化的时候有个密码）

2018-11-02T02:07:44.574468Z 1 [Note] A temporary password is generated for root@localhost: lXyB0%fi#9-S （这个就是密码）

mysql> help contents

ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

mysql> help contents

ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

mysql> show databases;

解决办法

1、 修改用户密码

mysql> alter user 'root'@'localhost' identified by 'youpassword';

或者

mysql> set password=password("youpassword");

2、刷新权限

mysql> flush privileges;

mysql> help contents
