YUM安装MySQL 8.0

Posted 2023-04-03 xyz叶子

 

安装官方yum

rpm -ivh https://repo.mysql.com//mysql57-community-release-el7-9.noarch.rpm

 

调试yum

关闭旧版本

yum-config-manager --disable mysql57-community

开启新版本

yum-config-manager --enable mysql80-community

安装mysql8.0

yum install mysql-community-server -y

安装完毕，启动mysql服务

systemctl start mysqld

第一次登陆，系统生成一个零时密码

grep \'temporary password\' /var/log/mysqld.log

更新密码

ALTER USER \'root\'@\'localhost\' IDENTIFIED BY \'MyNewPass4!\';

 

yum安装mysql5.5

今天早上到公司，想起昨天遇到到一个数据库字符集的问题，果断把服务器上的mysql删掉了，然后装mysql的步骤如下：
1，导入第三方源
rpm -Uvh http://repo.webtatic.com/yum/centos/5/latest.rpm
2，如果安装了低版本的mysql，删除
yum remove mysql mysql-*
3,安装libmysqlclient15
yum install libmysqlclient15 —enablerepo=webtatic
4,安装mysql5.5
yum install mysql55 mysql55-server -enalerepo=webtatic
在这一步的时候出现了如下错误：

Error: mysql55w-libs conflicts with mysql-libs-5.1.73-3.el6_5.x86_64

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles —nodigest
根据提示，在4的安装语句后添加参数—ship-broken此时仍然有错：
Processing Conflict: mysql55w-libs-5.5.40-1.w5.x86_64 conflicts mysql-libs < 5.5

Packages skipped because of dependency problems:

mysql-libs-5.1.73-3.el6_5.x86_64 from base

mysql55w-5.5.40-1.w5.x86_64 from webtatic

mysql55w-libs-5.5.40-1.w5.x86_64 from webtatic

mysql55w-server-5.5.40-1.w5.x86_64 from webtatic

perl-DBD-MySQL-4.013-3.el6.x86_64 from base
根据错误，应该时mysql-libs-5.1.73.el6_5.x86_64这个库版本低所致，然而用命令rpm -e mysql-libs-5.1.73-3.el6_5.x86_64 —nodeps删除时，却提示该包没有安装error: package mysql-libs-5.1.73-3.el6_5.x86_64 is not installed，一下就醉了！！！

参考技术A

同样遇到这个问题，我也是醉了我以前是这样解决的如果报错:Error:mysql55-libsconflictswithmysql-libs-5.1.71-1.el6.x86_64wgetftp://mirror.switch.ch/pool/1/mirror/mysql/Downloads/MySQL-6.0/MySQL-shared-compat-6.0.11-0.glibc23.x86_64.rpmrpm-ihvMySQL-shared-compat-6.0.11-0.glibc23.x86_64.rpm文件MySQL-shared-compat-6.0.11-0.glibc23.x86_64.rpm如何无法下载:参照此
