编译&安装
- make && make install
初始化数据库
- mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql
建立配置文件
- cat > /etc/my.cnf <<EOF
- [client]
- port=3306
- socket=/tmp/mysql.sock
- default-character-set=utf8
- #user=root
- #password=123
- [mysqld]

- basedir=/usr/local/mysql
- datadir=/data/mysql
- pid-file=/data/mysql/mysql.pid
- init-connect='SET NAMES utf8'
- character-set-server=utf8
- default-storage-engine=INNODB
- log_error=/data/mysql/mysql-error.log
- slow_query_log_file=/data/mysql/mysql-slow.log
- [mysqldump]
- quick
- max_allowed_packet=16M
- EOF
配置环境变量
- echo "PATH=/usr/local/mysql/bin:$PATH" >> /etc/profile
- source /etc/profile
配置启动脚本
- cp ../mysql-8.0.12/support-files/mysql.server /etc/init.d/mysqld
- vim /etc/init.d/mysqld
- chmod +x /etc/init.d/mysqld
- /etc/init.d/mysqld start
centos7系统自启动脚本
- cat /usr/lib/systemd/system/mysqld.service
- [Unit]

- ExecStart=/usr/local/mysql/bin/mysqld $MYSQLD_OPTS
- LimitNOFILE = 10000
- Restart=always
- RestartPreventExitStatus=1
- Environment=MYSQLD_PARENT_PID=1

启动MySQL
- systemctl start mysqld.service
修改root密码：使用WITH指定认证方式
- mysql -uroot
- ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '你的密码';
- ALTER USER 'root'@'localhost' IDENTIFIED WITH caching_sha2_password BY '你的密码';
查看密码字段和加密方式
- select host, user, authentication_string, plugin from user;
2、yum存储库安装MySQL
- wget https://dev.mysql.com/get/mysql80-community-release-el7-1.noarch.rpm
- yum localinstall mysql80-community-release-el7-1.noarch.rpm
- yum repolist enabled|grep "mysql.*-community.*"
- yum repolist all|grep mysql
- yum install mysql-community-server
- systemctl enable mysqld
- systemctl start mysqld
- netstat -lntup|grep 3306
查看随机生成的密码
- grep 'temporary password' /var/log/mysqld.log
- mysql -uroot -p
修改密码,密码必须要由大小写字母、数字和特性字符组成
- alter user 'root'@'localhost' identified by 'PJY@123.com';
- select version();
