本文介绍了解决在Linux系统上因已安装不同版本MySQL而导致的安装冲突问题的方法。通过检查和移除旧版本的MySQL库文件，确保新的MySQL版本能够成功安装。
1：也许之前的机器安装过Mysql，但是自己不知道，账号密码也忘记了，又执行安装操作，导致Mysql不兼容问题。Linux上安装MySQL时出现不兼容的解决办法，错误如下所示：

2：出现问题了，就解决呗，原因是系统已经安装了其他版本的mysql-libs包导致不兼容。
可以使用命令查看yum list | grep mysql，查看之前安装的mysql的信息，如下所示：
1 [root@master package]# yum list | grep mysql 2 Repository c6-media is listed more than once in the configuration 3 mysql-libs.i686 5.1.73-8.el6_8 @base 4 apr-util-mysql.i686 1.3.9-3.el6_0.1 base 5 bacula-director-mysql.i686 5.0.0-13.el6 base 6 bacula-storage-mysql.i686 5.0.0-13.el6 base 7 dovecot-mysql.i686 1:2.0.9-22.el6 base 8 freeradius-mysql.i686 2.2.6-7.el6_9 updates 9 libdbi-dbd-mysql.i686 0.8.3-5.1.el6 base 10 mod_auth_mysql.i686 1:3.0.0-11.el6_0.1 base 11 mysql.i686 5.1.73-8.el6_8 base 12 mysql-bench.i686 5.1.73-8.el6_8 base 13 mysql-connector-java.noarch 1:5.1.17-6.el6 base 14 mysql-connector-odbc.i686 5.1.5r1144-7.el6 base 15 mysql-devel.i686 5.1.73-8.el6_8 base 16 mysql-embedded.i686 5.1.73-8.el6_8 base 17 mysql-embedded-devel.i686 5.1.73-8.el6_8 base 18 mysql-server.i686 5.1.73-8.el6_8 base 19 mysql-test.i686 5.1.73-8.el6_8 base 20 pcp-pmda-mysql.i686 3.10.9-9.el6 base 21 php-mysql.i686 5.3.3-49.el6 base 22 qt-mysql.i686 1:4.6.2-28.el6_5 base 23 rsyslog-mysql.i686 5.8.10-10.el6_6 base 24 rsyslog7-mysql.i686 7.4.10-7.el6 base
3：将之前的mysql的lib包删除了即可，删除mysql-libs：
