1、下载Mysql5.7二进制包
打开mysql官网下载页面： https://dev.mysql.com/downloads/mysql/
2、解压到指定文件夹
2、解压到指定文件夹shell> tar zxvf mysql-5.7.33-linux-glibc2.12-x86_64.tar.gz -C /mysql/mysql57/app --strip-components=1
3、创建配置文件
shell> mv /etc/my.cnf /etc/my.cnf.bak shell> vim /mysql/mysql57/app/my.cnf [mysqld] user=mysql port=3307 basedir=/mysql/mysql57/app datadir=/mysql/mysql57/product/data socket=/mysql/mysql57/product/data/mysql.sock log_error=/mysql/mysql57/product/data/myerror.log server_id=57 log-bin=mysql-bin binlog_format=ROW
可根据实际情况和需求自行添加和调整参数
4、初始化MySQL5.7
shell> cd /mysql/mysql57/app shell> ./bin/mysqld --defaults-file=/mysql/mysql57/app/my.cnf --initialize shell> tail /mysql/mysql57/product/data/myerror.log 2021-03-03T01:44:49.248365Z 1 [Note] A temporary password is generated for root@localhost: qdcf_Vl>k8LP 获取数据库初始登录临时密码：qdcf_Vl>k8LP
5、添加环境变量
shell> vi /root/.bash_profile export PATH=/mysql/mysql57/app/bin:$PATH shell> source /root/.bash_profile
6、配置数据库服务
shell> cp /mysql/mysql57/app/support-files/mysql.server /etc/init.d/mysqld57 shell> vi /etc/init.d/mysqld57 basedir=/mysql/mysql57/app datadir=/mysql/mysql57/product/data
7、启停MySQL
shell> service mysqld57 start //启动mysql shell> service mysqld57 status //查看启动状态 shell> service mysqld57 stop //停止mysql
或者mysqld_safe启动MySQL服务
shell> /mysql/mysql57/app/bin/mysqld_safe --defaults-file=/mysql/mysql57/app/my.cnf --user=mysql &
8、修改root用户密码并登录
shell> mysqladmin -uroot -p"qdcf_Vl>k8LP" -S /mysql/mysql57/product/data/mysql.sock password "mysql" shell> mysql -uroot -pmysql -S /mysql/mysql57/product/data/mysql.sock
