5.7版本安装MySQL

rpm安装mysql

1.首先检查机器里是否已经存在MySQL

[root@localhost ~]# rpm -qa | grep mysql
mysql-community-server-5.7.14-1.el7.x86_64
mysql-community-libs-5.7.14-1.el7.x86_64
mysql-community-common-5.7.14-1.el7.x86_64
mysql-community-client-5.7.14-1.el7.x86_64
[root@localhost ~]#

2.去官网下载相应的rpm包：https://dev.mysql.com/downloads/mysql/并上传

[root@localhost ~]# ls
anaconda-ks.cfg  initial-setup-ks.cfg           
mysql-5.7.14-1.el7.x86_64.rpm-bundle.tar 
[root@localhost ~]#

3.解压mysql-5.7.14-1.el7.x86_64.rpm-bundle.tar

[root@localhost ~]# tar xf mysql-5.7.14-1.el7.x86_64.rpm-bundle.tar
[root@localhost ~]# ll

解压后会得到以下rpm安装文件：

4.查看并卸载mariadb 和 postfix

[root@localhost ~]# rpm -qa | grep ^mariadb
mariadb-libs-5.5.56-2.el7.x86_64
[root@localhost ~]# rpm -e mariadb-libs
error: Failed dependencies:
        libmysqlclient.so.18()(64bit) is needed by (installed) postfix-2:2.10.1-6.el7.x86_64
        libmysqlclient.so.18(libmysqlclient_18)(64bit) is needed by (installed) postfix-2:2.10.1-6.el7.x86_                                                          64

[root@localhost ~]# rpm -e mariadb-libs postfix
[root@localhost ~]# rpm -qa | grep ^mariadb
