这篇文章给大家分享的是有关centos7.2如何离线安装mysql5.7.18.tar.gz的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。

因为网络隔离，无法使用yum方式安装mysql，这里介绍linux服务器上手动离线安装mysql的方法。

目的

离线安装mysql服务
服务器：centos7.2，配置本地yum源
mysql版本：mysql5.7.18

步骤

1.下载安装包mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz，安装包传输到目的服务器/tmp目录
2.my.cnf文件（见文末）传输到目的服务器的/tmp目录
3.创建用户和相应文件夹：

#preparegroupaddmysqluseradd-r-gmysql-s/bin/falsemysqlyuminstall-yautoconfmkdir/appsmkdir/logsmkdir/datamkdir-p/data/mysql7006/data&&chown-Rmysql:mysql/data/mysql7006mkdir/logs/mysql7006&&chown-Rmysql:mysql/logs/mysql7006touch/logs/mysql7006/error-log.err&&chown-Rmysql:mysql/logs/mysql7006/error-log.err

4.安装

cd/tmptarzxvfmysql-5.7.18-linux-glibc2.5-x86_64.tar.gzmvmysql-5.7.18-linux-glibc2.5-x86_64mysqlmvmysql/apps/mysqlcpmy.cnf/apps/mysql/chown-Rmysql:mysql/apps/mysql/#初始化数据库，cd/apps/mysql./bin/mysqld--initialize--user=mysql--basedir=/apps/mysql/--datadir=/data/mysql7006/data/

初始化过程中会生成一个默认密码记得记下来，后续修改用。

5.注册service（可以不做）

#依据情况修改support-files/mysql.servercpsupport-files/mysql.server/etc/init.d/mysqlsystemctlstartmysql.service#添加开机启动chkconfigmysql.serveron

6.启动数据库/apps/mysql/bin/mysqld_safe --defaults-file=/apps/mysql/my.cnf &

7.修改默认密码：

/apps/mysql/bin/mysqladmin-urootpassword'password'--port=7006--socket=/data/mysql7006/mysql.sock-p#修改后清空linux的history记录history-c#登陆测试：/apps/mysql/bin/mysql-uroot--port=7006--socket=/data/mysql7006/mysql.sock-p

8.防火墙、赋权（按需做）

#防火墙firewall-cmd--zone=public--add-port=7006/tcp--permanentsystemctlrestartfirewalldfirewall-cmd--zone=public--query-port=7006/tcp#赋权给登陆用户usemysql;grantallprivilegeson*.*touser@'ip'identifiedby"password";flushprivileges;selecthost,user,passwordfromuser;

9.本地隐藏密码登录（可以不做）

##使用mysql_config_editor制作登录文件/apps/mysql/bin/mysql_config_editorset--login-path=root_pass--user=root--port=7006--socket=/data/mysql7006/mysql.sock--password##输入密码：******##文件会加密存储于用户根目录下.mylogin.cnf/apps/mysql/bin/mysql_config_editorprint--all##下次登录时直接敲：/apps/mysql/bin/mysql--login-path=root_pass#再省事一些：setalias#打开file.bashrc，添加aliasdb7006='/apps/mysql/bin/mysql--login-path=root_pass'#然后退出执行：source.bashrc##下次登录时直接敲：db7006

附录

my.cnf文件

主要功能：全局utf8字符集、自定义端口、数据文件夹、日志文件夹、默认引擎innodb（支持事务，对xtrabackup友好）、跳过客户端登陆时的dns解析
