这篇文章主要讲解了“Linux下安装MySQL5.7的步骤”，文中的讲解内容简单清晰，易于学习与理解，下面请大家跟着小编的思路慢慢深入，一起来研究和学习“Linux下安装MySQL5.7的步骤”吧！ 本次将在Linux下通过yum安装MySQL，安装的版本为MySQL 5.7，官网中是最新版本8.0，在网上查了下，发现最新版本的yum源也包含了旧版本，而我们，只需要在安装时启用 5.7 的安装即可。 本人环境：CentOS 7.3 64位 检查CentOS是否有系统自带的mysql yum list installed | grep mysql 如果存在系统自带的mysql及依赖，则通过 yum remove 将其卸载 修改默认安装版本为5.7 从上面的图片，我们可以看到，默认是MySQL 8.0可用，我们若想安装MySQL 5.7，则需启用5.7。接下来通过直接修改配置文件来设置启用。 vim /etc/yum.repos.d/mysql-community.repo 输入上面的命令，在编辑界面，先输入 i 进入编辑模式，将8.0的 enabled 设置为0，将5.7的 enabled 设置为1，如下： Linux下安装MySQL5.7的步骤 接着按 Esc 退出编辑模式，最后输入 :wq 保存并退出。 再次输入命令：yum repolist all | grep mysql ，可以看到8.0已被禁用，而5.7是启用的。 Linux下安装MySQL5.7的步骤 安装MySQL yum install mysql-community-server 输入上面命令，进行安装即可。 点我复制[root@wintest mysql]# yum install mysql-community-server Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile Resolving Dependencies--> Running transaction check---> Package mysql-community-server.x86_64 0:5.7.27-1.el7 will be installed--> Processing Dependency: mysql-community-common(x86-64) = 5.7.27-1.el7 for package: mysql-community-server-5.7.27-1.el7.x86_64--> Processing Dependency: mysql-community-client(x86-64) >= 5.7.9 for package: mysql-community-server-5.7.27-1.el7.x86_64--> Processing Dependency: libaio.so.1(LIBAIO_0.4)(64bit) for package: mysql-community-server-5.7.27-1.el7.x86_64--> Processing Dependency: libaio.so.1(LIBAIO_0.1)(64bit) for package: mysql-community-server-5.7.27-1.el7.x86_64--> Processing Dependency: libaio.so.1()(64bit) for package: mysql-community-server-5.7.27-1.el7.x86_64--> Running transaction check---> Package libaio.x86_64 0:0.3.109-13.el7 will be installed---> Package mysql-community-client.x86_64 0:5.7.27-1.el7 will be installed--> Processing Dependency: mysql-community-libs(x86-64) >= 5.7.9 for package: mysql-community-client-5.7.27-1.el7.x86_64---> Package mysql-community-common.x86_64 0:5.7.27-1.el7 will be installed--> Running transaction check---> Package mariadb-libs.x86_64 1:5.5.52-1.el7 will be obsoleted--> Processing Dependency: libmysqlclient.so.18()(64bit) for package: 2:postfix-2.10.1-6.el7.x86_64--> Processing Dependency: libmysqlclient.so.18(libmysqlclient_18)(64bit) for package: 2:postfix-2.10.1-6.el7.x86_64---> Package mysql-community-libs.x86_64 0:5.7.27-1.el7 will be obsoleting--> Running transaction check---> Package mysql-community-libs-compat.x86_64 0:5.7.27-1.el7 will be obsoleting---> Package postfix.x86_64 2:2.10.1-6.el7 will be updated---> Package postfix.x86_64 2:2.10.1-7.el7 will be an update--> Finished Dependency ResolutionDependencies Resolved ==================================================================================== Package Arch Version Repository Size ==================================================================================== Installing: mysql-community-libs x86_64 5.7.27-1.el7 mysql57-community 2.2 M replacing mariadb-libs.x86_64 1:5.5.52-1.el7 mysql-community-libs-compat x86_64 5.7.27-1.el7 mysql57-community 2.0 M replacing mariadb-libs.x86_64 1:5.5.52-1.el7 mysql-community-server x86_64 5.7.27-1.el7 mysql57-community 165 M Installing for dependencies: libaio x86_64 0.3.109-13.el7 base 24 k mysql-community-client x86_64 5.7.27-1.el7 mysql57-community 24 M mysql-community-common x86_64 5.7.27-1.el7 mysql57-community 275 k Updating for dependencies: postfix x86_64 2:2.10.1-7.el7 base 2.4 M Transaction Summary ==================================================================================== Install 3 Packages (+3 Dependent packages) Upgrade ( 1 Dependent package) Total download size: 197 MIs this ok [y/d/N]: y Downloading packages: Delta RPMs disabled because /usr/bin/applydeltarpm not installed.
