[mysqld] datadir = /var/mysql/data log_error = /usr/local/mysql/data/error tmpdir = /var/tmp |
3.vim /etc/hosts
127.0.0.1 root
4. /usr/local/mysql/script/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --data=/var/mysql/data/ & 生成系统数据库
5.接下来我们通过生成系统数据库的方式将进程文件写入进去
/usr/local/mysql/bin/mysqld_safe --user=mysql --basedir=/usr/local/mysql/ --data=/var/mysql/data/ &
&是后台 运行的意思
接着重启一下就好了
