由于工作需要，需要在一台装有 CentOS 系统的测试服务器上安装 MySQL ，由于该服务器上存有其他比较重要的测试数据，所以不能连接外网。由于之前安装 MySQL 一直都是使用 yum 命令一键搞定的，所以手动安装的话还是有些麻烦的。所以在这里我将我在安装过程中遇到的一些问题记录下来。
1.需求就不用讲了，客户现场，政府环境，银行环境，大多是没网的，所以无网安装是很有必要的
mysql下载路径：https://dev.mysql.com/downloads/mysql/
查看自己Linux系统版本
[root@linuxidc ~]# cat /etc/RedHat-release
CentOS Linux release 7.3.1611 (Core)
往下拉继续选择
选择对应的下载，mysql-5.7.20-1.el7.x86_64.rpm-bundle.tar
这样几分钟就下载了。
2.准备依赖包：
a.numactl 软件包：
numactl-2.0.9-6.el7_2.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
b.其他相关支持：
perl-Data-Dumper-2.145-3.el7.x86_64.rpm
libaio-0.3.109-13.el7.x86_64.rpm
下载方式：https://pkgs.org
下面是下载路径：
libaio-0.3.109-13.el7.x86_64.rpm
perl-Data-Dumper-2.145-3.el7.x86_64.rpm
numactl-libs-2.0.9-6.el7_2.x86_64.rpm
numactl-devel-2.0.9-6.el7_2.x86_64.rpm
numactl-2.0.9-6.el7_2.x86_64.rpm
3.上传文件到服务器上
localhost:Downloads kylin$ scp -r numactl-2.0.9-6.el7_2.x86_64.rpm root@linuxidc:/root/

查看上传的包
[root@linuxidc ~]# ls
anaconda-ks.cfg numactl-devel-2.0.9-6.el7_2.x86_64.rpm
libaio-0.3.109-13.el7.x86_64.rpm numactl-libs-2.0.9-6.el7_2.x86_64.rpm
miniconda2 perl-Data-Dumper-2.145-3.el7.x86_64.rpm
mysql-5.7.20-1.el7.x86_64.rpm-bundle.tar Pythonshell
numactl-2.0.9-6.el7_2.x86_64.rpm
4.安装
第一步，先安装依赖，安装 perl-Data-Dumper-2.145-3.el7.x86_64.rpm 和 libaio-0.3.109-13.el7.x86_64.rpm
[root@linuxidc ~]# rpm -ivh libaio-0.3.109-13.el7.x86_64.rpm
Preparing... ################################# [100%]
package libaio-0.3.109-13.el7.x86_64 is already installed
[root@linuxidc ~]# rpm -ivh perl-Data-Dumper-2.145-3.el7.x86_64.rpm
Preparing... ################################# [100%]
Updating / installing...
1:perl-Data-Dumper-2.145-3.el7 ################################# [100%]
第二步，继续安装 numactl相关
[root@linuxidc ~]# rpm -ivh numactl*
Preparing... ################################# [100%]
package numactl-libs-2.0.9-6.el7_2.x86_64 is already installed
如果不安装这个包会报错，错误如下（本人未测试）：
error: Failed dependencies:
libnuma.so.1()(64bit) is needed by mysql-community-server-5.7.18-1.el7.x86_64
libnuma.so.1(libnuma_1.1)(64bit) is needed by mysql-community-server-5.7.18-1.el7.x86_64
libnuma.so.1(libnuma_1.2)(64bit) is needed by mysql-community-server-5.7.18-1.el7.x86_64
若此时直接安装mysql，还会异常：
