参考文档mysql5.7安装http://blog.itpub.net/70004783/viewspace-2794003/ 仅列出区别的地方 4、安装mysql8.0
xz -d mysql-8.0.26-linux-glibc2.12-x86_64.tar.xz tar xvf mysql-8.0.26-linux-glibc2.12-x86_64.tar mv mysql-8.0.26-linux-glibc2.12-x86_64 /u01/app/mysql
6、配置参数文件
[root@dbserver 3306]# cat /u01/data/3306/my.cnf [mysql] default-character-set=utf8mb4 socket=/u01/data/3306/mysql.sock [mysqld] #skip-name-resolve port = 3306 socket=/u01/data/3306/mysql.sock basedir=/u01/app/mysql datadir=/u01/data/3306/data character-set-server=utf8mb4 default-storage-engine=INNODB innodb_buffer_pool_size = 200M max_allowed_packet=16M explicit_defaults_for_timestamp=1 log-output=FILE general_log = 0 general_log_file=/u01/log/3306/3306db-general.err slow_query_log = ON slow_query_log_file=/u01/log/3306/3306db-query.err long_query_time=10 log-error=/u01/log/3306/3306db-error.err #mysql5.7的密码策略，8.0很多客户端不支持 default-authentication-plugin=mysql_native_password
