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

\# 如果出现以下错误：

![48304ba5e6f9fe08f3fa1abda7d326ab.png][]

2018-07-14 06:40:32 \[WARNING\] mysql\_install\_db is deprecated. Please consider switching to mysqld --initialize

2018-07-14 06:40:32 \[ERROR\] Child process: /usr/local/mysql/bin/mysqldterminated prematurely with errno= 32

2018-07-14 06:40:32 \[ERROR\] Failed to execute /usr/local/mysql/bin/mysqld --bootstrap --datadir=/usr/local/mysql/data --lc-messages-dir=/usr/local/mysql/share --lc-messages=en\_US --basedir=/usr/local/mysql

\-- server log begin --

\-- server log end --

![48304ba5e6f9fe08f3fa1abda7d326ab.png][]

\# 则使用以下命令：

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

\# 如果出现以下错误：

/usr/local/mysql/bin/mysqld: error while loading shared libraries: libnuma.so.1: cannot open shared object file: No such file or directory

\# 则执行以下命令：

yum -y install numactl

\# 完成后继续安装：

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

\# 编辑/etc/my.cnf

按 Ctrl+C 复制代码

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
