我试图在CentOS 6.2中将MysqL从5.1更新到5.5。以下是我所做的过程：
1. rpm -Uvh http://repo.webtatic.com/yum/centos/5/latest.rpm 2. yum install libMysqLclient15 --enablerepo=webtatic 3. yum remove MysqL MysqL-* 4. yum install MysqL55 MysqL55-server --enablerepo=webtatic
当我尝试第四步，我得到以下输出：
[root@d2005 /]# yum install MysqL55 MysqL55-server --enablerepo=webtatic Failed to set locale,defaulting to C Loaded plugins: fastestmirror,presto Loading mirror speeds from cached hostfile * base: yum.singlehop.com * extras: centos.mirrors.tds.net * updates: pubmirrors.reflected.net Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package MysqL55.x86_64 0:5.5.10-1.w5 will be installed --> Processing Dependency: MysqL55-libs = 5.5.10-1.w5 for package: MysqL55-5.5.10-1.w5.x86_64 ---> Package MysqL55-server.x86_64 0:5.5.10-1.w5 will be installed --> Processing Dependency: perl-dbd-mysql for package: MysqL55-server-5.5.10-1.w5.x86_64 --> Running transaction check ---> Package MysqL55-libs.x86_64 0:5.5.10-1.w5 will be installed ---> Package perl-dbd-mysql.x86_64 0:4.013-3.el6 will be installed --> Processing Dependency: libMysqLclient.so.16(libMysqLclient_16)(64bit) for package: perl-dbd-mysql-4.013-3.el6.x86_64 --> Processing Dependency: libMysqLclient.so.16()(64bit) for package: perl-dbd-mysql-4.013-3.el6.x86_64 --> Running transaction check ---> Package MysqL-libs.x86_64 0:5.1.61-1.el6_2.1 will be installed --> Processing Conflict: MysqL55-libs-5.5.10-1.w5.x86_64 conflicts MysqL-libs < 5.5.10 --> Finished Dependency Resolution Error: MysqL55-libs conflicts with MysqL-libs You Could try using --skip-broken to work around the problem You Could try running: rpm -Va --nofiles --nodigest
如何解决？
列出Old MysqL
yum list installed | grep -i MysqL
删除旧MysqL
yum remove MysqL MysqL-*
Remi依赖于CentOS 6和Red Hat(RHEL)6
rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
安装MysqL服务器
yum --enablerepo=remi,remi-test install MysqL MysqL-server
列出新的MysqL
yum list installed | grep -i MysqL
启动MysqL服务器
/etc/init.d/MysqLd start ##更新后使用restart
要么
service MysqLd start ##更新后使用restart
chkconfig --levels 235 MysqLd on
持续
MysqL_upgrade -u root -p
现在我的MysqL版本是5.5.32

Just wanted to add that after the upgrade,my crontab was removed as well. Had to reinstall with "yum install vixie-cron" (CentOS 6)
