1.配置YUM源 下载mysql源安装包: wget https://repo.mysql.com//mysql57-community-release-el7-11.noarch 安装mysql源,安装过程中遇到Is this ok [y/d/N]的直接输入y即可: yum localinstall mysql57-community-release-el7-11.noarch.rpm 检查mysql源是否安装成功: yum repolist enabled | grep "mysql.*-community.*"
2.安装MySQL,安装过程中遇到Is this ok [y/d/N]的直接输入y即可 yum install mysql-community-server Note:可通过修改/etc/yum.repos.d/mysql-community.repo源中的enabled【1表示选择】的值来选择安装的MySQL版本
3.启动MySQL服务 systemctl start mysqld 查看MySQL的启动状态 systemctl status mysqld
4.开机启动 systemctl enable mysqld systemctl daemon-reload
5.修改root本地登录密码 获取MySQL默认密码: grep 'temporary password' /var/log/mysqld.log 登陆MySQL: mysql -uroot -p 修改默认密码: ALTER USER 'root'@'localhost' IDENTIFIED BY 'Password'; 或者 set password for 'root'@'localhost'=password('Password'); Note:MySQL5.7默认安装了密码安全检查插件(validate_password),默认密码检查策略要求密码必须包含:大小写字母、数字和特殊符号,并且长度不能少于8位。
6.添加远程登录用户 默认只允许root帐户在本地登录,如果要在其它机器上连接mysql,必须修改root允许远程连接,或者添加一个允许远程连接的帐户: GRANT ALL PRIVILEGES ON *.* TO 'account'@'%' IDENTIFIED BY 'pwd' WITH GRANT OPTION;
7.配置默认编码为utf8 show variables like '%character%'; 修改/etc/my.cnf配置文件: [mysqld] character_set_server=utf8 init_connect='SET NAMES utf8' 重新启动mysql服务即可完成修改
8.默认配置文件路径 配置文件:/etc/my.cnf 日志文件:/var/log//var/log/mysqld.log 服务启动脚本:/usr/lib/systemd/system/mysqld.service socket文件:/var/run/mysqld/mysqld.pid (责任编辑:IT) |
