解压安装包

移除已经安装的早期版本
如果不移除的话,会提示有冲突,版本可能有所不同
yum -y remove mysql-libs-5.1.73
安装顺序
rpm -ivh mysql-community-common-5.7.12-1.el6.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.12-1.el6.x86_64.rpm

# service mysqld start

正在启动 mysqld:
修改管理员密码
查看初始管理员密码,下面的命令适用于 RHEL, Oracle Linux, CentOS, and Fedora 平台:
grep ‘temporary password’ /var/log/mysqld.log
SLES平台使用下面的命令:
grep ‘temporary password’ /var/log/mysql/mysqld.log
你会发现初始密码超级的复杂,还好我使用XShell,可以复制粘贴
# grep ‘temporary password’ /var/log/mysqld.log

注意:这种写法(mysql -uroot -p?sSq8?.IucXV)有时因密码中的特殊字符而不可行,需要先执行(mysql -uroot -p),再根据提示输入密码。
使用下面的命令修改密码
ALTER USER ‘root’@’localhost’ IDENTIFIED BY ‘MyNewPass4!’;
密码必须包含大写字母小写字母数字和符号,不然会提示:ERROR 1819 (HY000): Your password does not satisfy the current policy requirements(您的密码不符合当前的安全策略要求)
报错的解决方法:
yum install perl-JSON.noarch
yum install numactl
由于yum安装了旧版本的GPG keys造成的,解决办法就是(设置后无效)
- rpm –import /etc/pki/rpm-gpg/RPM* 参考:http://blog.csdn.net/typa01_kk/article/details/49059729
