无网络环境下安装MySQL5.7

前提:

1、系统环境:CentOS 7 64bit

2、需要的rpm包已经在本地

安装:

1、下载需要的rpm包:

mysql-community-client-5.7.18-1.el7.x86_64.rpm
mysql-community-common-5.7.18-1.el7.x86_64.rpm
mysql-community-libs-5.7.18-1.el7.x86_64.rpm
mysql-community-server-5.7.18-1.el7.x86_64.rpm

numactl-devel-2.0.9-6.el7_2.x86_64.rpm
numactl-libs-2.0.9-6.el7_2.x86_64.rpm
perl-Data-Dumper-2.145-3.el7.x86_64.rpm
libaio-0.3.109-13.el7.x86_64.rpm

推荐一个比较不错的下载网站:https://pkgs.org/

2、安装rpm:

注意安装顺序

rpm -ivh libaio-0.3.109-13.el7.x86_64.rpm
rpm -ivh perl-Data-Dumper-2.145-3.el7.x86_64.rpm
rpm -ivh numactl-libs-2.0.9-6.el7_2.x86_64.rpm
rpm -ivh numactl-devel-2.0.9-6.el7_2.x86_64.rpm
rpm -ivh numactl-2.0.9-6.el7_2.x86_64.rpm
rpm -ivh mysql-community-common-5.7.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-5.7.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-5.7.18-1.el7.x86_64.rpm

若安装时出现冲突，需要将以安装的卸载掉(rpm -e)，然后继续安装。

安装完毕后，启动mysql：

service mysqld start

启动后进入MySQL时，会提示输入密码，该密码是初次安装是默认生成并保存在/var/log/mysqld.log中，可以通过一下命令查看:

cat /var/log/mysqld.log | grep password

输入密码登陆后，执行SQL语句时，会提示让修改密码，执行以下三句:

1: SET PASSWORD = PASSWORD('new password');
2: ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
3: flush privileges;

退出后再次登陆，OK。
