mysql-5.7.15编译安装

1、准备安装包 mysql-5.7.15-linux-glibc2.5-x86_64.tar.gz，解压

[root@T-DMP-01 ~]# tar zxf mysql-5.7.15-linux-glibc2.5-x86_64.tar.gz -C /data/
[root@T-DMP-01 data]# ln -s /data/mysql-5.7.15-linux-glibc2.5-x86_64/ /data/mysql
[root@T-DMP-01 data]# cd /data/mysql
[root@T-DMP-01 ~]#mkdir data  //新建文件夹data
[root@T-DMP-01 ~]#mkdir mysql-files
[root@T-DMP-01 ~]#groupadd mysql　//新建mysql组
[root@T-DMP-01 ~]#useradd -g mysql mysql
[root@T-DMP-01 ~]#chown -R mysql:mysql /data/mysql

2、修改配置文件/etc/my.cnf

[root@T-DMP-01 mysql]# cat /etc/my.cnf
[mysqld]
port=3306
basedir=/data/mysql
datadir=/data/mysql/data
socket=/data/mysql/mysql.sock
log_error=/data/mysql/mysql_error.log

[client]
port=3306
socket=/data/mysql/mysql.sock

3、初始化数据库

[root@T-DMP-01 bin]# ./mysqld --initialize --user=mysql --basedir=/data/mysql --datadir=/data/mysql/data

查看密码：

[root@T-DMP-01 mysql]# bin/mysql_ssl_rsa_setup --datadir=/data/mysql/data    //设置ssl可以不用执行

4、启动MySQL

[root@T-DMP-01 support-files]# su mysql

[mysql@T-DMP-01 support-files]# ./mysql.server start
Starting MySQL. SUCCESS!
[mysql@T-DMP-01 support-files]# pwd
/data/mysql/support-files

5、修改密码

[mysql@localhost bin]$ ./mysqladmin -u root -p password 'JchangI2021';

6、给root赋予远程登陆权限

mysql> grant  all  on  *.*  to  root@'%' identified  by 'WWW.1.com' with grant option;
