Linux系统之安装mysql数据库
【摘要】 Linux系统之安装mysql数据库
一、查看系统版本
[root@node ~]# cat /etc/os-release
NAME="CentOS Linux"
VERSION="7 (Core)"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="7"
PRETTY_NAME="CentOS Linux 7 (Core)"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:centos:centos:7"
HOME_URL="https://www.centos.org/"
BUG_REPORT_URL="https://bugs.centos.org/"
CENTOS_MANTISBT_PROJECT="CentOS-7"
CENTOS_MANTISBT_PROJECT_VERSION="7"
REDHAT_SUPPORT_PRODUCT="centos"
REDHAT_SUPPORT_PRODUCT_VERSION="7"
二、检查yum仓库
[root@node ~]# yum repolist all |grep enable
!base/7/x86_64 CentOS-7 - Base enabled: 10,072
!docker-ce-stable/7/x86_64 Docker CE Stable - x86_64 enabled: 183
!extras/7/x86_64 CentOS-7 - Extras enabled: 515
!mongodb-org/7 MongoDB Repository enabled: 187
!updates/7/x86_64 CentOS-7 - Updates enabled: 4,346
三、检查mysql是否安装
[root@node yum.repos.d]# rpm -qa | grep mysql
[root@node yum.repos.d]#
四、配置mysql的yum源
1.配置yum仓库
[root@node yum.repos.d]# yum localinstall https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm
Loaded plugins: fastestmirror, langpacks
mysql57-community-release-el7-11.noarch.rpm | 25 kB 00:00:00
Examining /var/tmp/yum-root-pXEqvj/mysql57-community-release-el7-11.noarch.rpm: mysql57-community-release-el7-11.noarch
Marking /var/tmp/yum-root-pXEqvj/mysql57-community-release-el7-11.noarch.rpm to be installed

2.查看mysql-community.repo
[root@node yum.repos.d]# cat mysql-community.repo
