在系统无法上网，也没有光驱镜像文件的环境下安装mysql

#系统：centos 7 #mysql在centos7当中的安装包名为服务端mariadb-server和客户端mariadb： 第一步：在可联网的centos7系统上新建一个Yum仓库目录 mkdir mariadb-yumrepo

第二步：使用如下命令下载mysql安装所需要的包到yum仓库目录中 yum install --downloadonly --downloaddir=/mariadb-yumrepo mariadb-server mariadb

第三步：通过yum安装创建元数据的索引命令工具createrepo yum install createrepo

第四步：通过createrepo工具为mariadb-yumrepo目录下的服务包建立索引元数据 createrepo /mariadb-yumrepo

第五步：将目录打包，上传到需要安装mysql服务的系统上 tar -zcvf mariadb-yumreop.tar.gz /mariadb-yumrepo

第六步：在需要安装mysql服务的系统上，解压上面打包好的文件， tar -zxvf mariadb-yumreop.tar.gz -C /var/ [root@Centos 7 /]# cd /var/mariadb-yumrepo/ [root@Centos 7 /var/mariadb-yumrepo]# pwd /var/mariadb-yumrepo [root@Centos 7 /var/mariadb-yumrepo]# ls mariadb-5.5.68-1.el7.x86_64.rpm mariadb-server-5.5.68-1.el7.x86_64.rpm perl-Compress-Raw-Bzip2-2.061-3.el7.x86_64.rpm perl-Compress-Raw-Zlib-2.061-4.el7.x86_64.rpm perl-Data-Dumper-2.145-3.el7.x86_64.rpm perl-DBD-MySQL-4.023-6.el7.x86_64.rpm perl-DBI-1.627-4.el7.x86_64.rpm perl-IO-Compress-2.061-2.el7.noarch.rpm perl-Net-Daemon-0.48-5.el7.noarch.rpm perl-PlRPC-0.2020-14.el7.noarch.rpm repodata

第七步：根据此目录文件建立本地yum仓库 [root@Centos 7 /var/mariadb-yumrepo]# cd /etc/yum.repos.d/ [root@Centos 7 /etc/yum.repos.d]# vim bendiyum.repo [mariadb-server] name=mysql isntall server baseurl=file:///var/mariadb-yumrepo/ gpgcheck=0 #建立元数据 [root@Centos 7 /etc/yum.repos.d]# yum makecache

第八步：开始安装mysql服务 [root@Centos 7 /etc/yum.repos.d]# yum install mariadb-server mariadb Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile Resolving Dependencies --> Running transaction check ---> Package mariadb.x86_64 1:5.5.68-1.el7 will be installed ---> Package mariadb-server.x86_64 1:5.5.68-1.el7 will be installed --> Processing Dependency: perl-DBI for package: 1:mariadb-server-5.5.68-1.el7.x86_64 --> Processing Dependency: perl-DBD-MySQL for package: 1:mariadb-server-5.5.68-1.el7.x86_64 --> Processing Dependency: perl(Data::Dumper) for package: 1:mariadb-server-5.5.68-1.el7.x86_64 --> Processing Dependency: perl(DBI) for package: 1:mariadb-server-5.5.68-1.el7.x86_64 --> Running transaction check ---> Package perl-DBD-MySQL.x86_64 0:4.023-6.el7 will be installed ---> Package perl-DBI.x86_64 0:1.627-4.el7 will be installed --> Processing Dependency: perl(RPC::PlServer) >= 0.2001 for package: perl-DBI-1.627-4.el7.x86_64 --> Processing Dependency: perl(RPC::PlClient) >= 0.2000 for package: perl-DBI-1.627-4.el7.x86_64 ---> Package perl-Data-Dumper.x86_64 0:2.145-3.el7 will be installed --> Running transaction check ---> Package perl-PlRPC.noarch 0:0.2020-14.el7 will be installed --> Processing Dependency: perl(Net::Daemon) >= 0.13 for package: perl-PlRPC-0.2020-14.el7.noarch --> Processing Dependency: perl(Net::Daemon::Test) for package: perl-PlRPC-0.2020-14.el7.noarch --> Processing Dependency: perl(Net::Daemon::Log) for package: perl-PlRPC-0.2020-14.el7.noarch --> Processing Dependency: perl(Compress::Zlib) for package: perl-PlRPC-0.2020-14.el7.noarch --> Running transaction check ---> Package perl-IO-Compress.noarch 0:2.061-2.el7 will be installed --> Processing Dependency: perl(Compress::Raw::Zlib) >= 2.061 for package: perl-IO-Compress-2.061-2.el7.noarch --> Processing Dependency: perl(Compress::Raw::Bzip2) >= 2.061 for package: perl-IO-Compress-2.061-2.el7.noarch ---> Package perl-Net-Daemon.noarch 0:0.48-5.el7 will be installed --> Running transaction check ---> Package perl-Compress-Raw-Bzip2.x86_64 0:2.061-3.el7 will be installed ---> Package perl-Compress-Raw-Zlib.x86_64 1:2.061-4.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved =================================================================================== Package Arch Version Repository Size =================================================================================== Installing: mariadb x86_64 1:5.5.68-1.el7 mariadb-server 8.8 M mariadb-server x86_64 1:5.5.68-1.el7 mariadb-server 11 M Installing for dependencies: perl-Compress-Raw-Bzip2 x86_64 2.061-3.el7 mariadb-server 32 k perl-Compress-Raw-Zlib x86_64 1:2.061-4.el7 mariadb-server 57 k perl-DBD-MySQL x86_64 4.023-6.el7 mariadb-server 140 k perl-DBI x86_64 1.627-4.el7 mariadb-server 802 k perl-Data-Dumper x86_64 2.145-3.el7 mariadb-server 47 k perl-IO-Compress noarch 2.061-2.el7 mariadb-server 260 k perl-Net-Daemon noarch 0.48-5.el7 mariadb-server 51 k perl-PlRPC noarch 0.2020-14.el7 mariadb-server 36 k Transaction Summary =================================================================================== Install 2 Packages (+8 Dependent packages) Total download size: 21 M Installed size: 110 M Is this ok [y/d/N]: y Downloading packages:
