将压缩包上传到/usr/local中,然后进入local中。解压 mysql 的压缩包 tar -zxvf mysql-5.7.12-linux-glibc2.5-x86_64.tar.gz。
添加mysql组合mysql用户 (groupadd mysql) (useradd -r -g mysql mysql)
进入mysql (cd mysql) ,修改当前目录拥有者为mysql用户:(chown -R mysql:mysql ./)
初始化配置表命令::执行命令./bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data/
-user 启动mysql的用户
--basedir mysql安装目录
--datadir mysql数据仓库目录
将mysql/目录下除了data/目录的所有文件,改回root用户所有,mysql用户只需作为mysql/data/目录下所有文件的所有者。
(chown -R root . )
(chown -R mysql data)
将一下内容粘贴到my.cnf中
