1.
配置yum源:
[root@yyf ~]#rpm -Uvh http://dev.mysql.com/get/mysql-community-release-el6-5.noarch.rpm
[root@yyf ~]#yum-config-manager --disable mysql56-community
[root@yyf ~]#yum-config-manager --enable mysql57-community-dmr
[root@yyf ~]#yum -y install mysql-community-server.x86_64
2.初始化数据库:
mysql5.77中是通过mysqld --initialize 来初始化数据库,而不是通过mysql_install_db,如:
[root@yyf ~]#mysqld --initialize --user=mysql --basedir=/var/lib/mysql --datadir=/data1/db3306/
3.登入数据库,5.77中增强了root登入的安全性,在初始化数据库时,就给root生成了一个随机密码,并且登入后强制要求修改密码。
在数据库的错误日志里记录了该随机密码:
[Warning] A temporary password is generated for root@localhost: (6dnJ0gwO+y5
[root@yyf ~]#mysql -uroot -p(6dnJ0gwO+y5
[root@yyf ~]#
mysql> status;

mysql> SET PASSWORD = 'root';
