下载路径：

https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz

2.1#创建mysql的数据目录，该目录在初始化数据库的候会用到

mkdir -p /data/mysql/data

mkdir -p /data/mysql/log

 

2.2#移动mysql文件到/data/mysql/mysql

tar -zxvf mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz -C /usr/local/

cd /usr/local/

ln -s mysql-5.7.26-linux-glibc2.12-x86_64 mysql

2.3 #先创建mysql组

groupadd mysql

2.4#将MySQL用户加入mysql组

useradd -r -g mysql -s /bin/false mysql     

2.5#修改目录权限

chown -R mysql:mysql /data/mysql/

chmod 750 /data/mysql

2.6#配置my.cnf

ls -l /etc/my.cnf ##查看是不是已经有my.cnf配置了，如果有可能是centos自带了Mysql数据库，我用的是7.5，自带mysql 的mariadb，下面我将把它卸载，避免受到干扰

rpm -e mariadb-libs --nodeps ##mariadb

vim /etc/my.cnf

2.7#初始化数据库

 

/usr/local/mysql/bin/mysqld --defaults-file=/etc/my.cnf --initialize --user=mysql --basedir=/data/mysql/mysql --datadir=/data/mysql/data --innodb_undo_tablespaces=3 --explicit_defaults_for_timestamp #初始化mysql

2.7#根据配置了my.cnf的error.log，查看初始密码

grep 'password' /data/mysql/log/mysql-error.log  

 2.8#创建ssl加密

/usr/local/mysql/bin/mysql_ssl_rsa_setup --datadir=/data/mysql/data

2.9#将里面的basedir和datadir改为和my.cnf一致

vi /usr/local/mysql/support-files/mysql.server            

basedir=/usr/local/mysql

datadir=/data/mysql/data

2.10#拷贝和配置启动文件

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld     

2.11设置开机启动

chkconfig --add mysqld

chkconfig mysqld on

 

2.12配置环境变量

echo 'PATH=/usr/local/mysql/bin:$PATH'>>/etc/profile

tail -1 /etc/profile

source /etc/profile   #让环境变量生效

echo $PATH #检查变量是否添加成功

2.13#启动mysql

service mysqld start 

2.14#进入mysql

mysql -uroot -p         #密码通过前面的2.2.7找到

2.15#修改初始密码

ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';    

2.16#刷新权限

flush privileges; 

2.17加入开机启动项
