a.检查下linux是不是已经安装了mysql [root@CentOS ~]# rpm -qa | grep -i mysql #grep -i是不分大小写字符查询,只要含有mysql就显示 mysql-libs-5.1.71-1.el6.i686 #如果安装了先卸载旧的版本 [root@CentOS ~]# yum -y remove mysql-libs [root@CentOS ~]# rpm -qa | grep -i mysql 屏幕显示: mysql-libs-5.1.71-1.el6.i686 //它是好几个软件的依赖,其中在mini版本中postfix软件依赖mysql-libs,网络上很多建议都是直接删除, yum remove mysql-libs 或者 rpm -e --nodeps mysql-libs-5.1.71-1.el6.i686,总觉得这样做不好。 查找mysql官方资料,得到安装方法是用MySQL-shared-compat将mysql-libs-5.1.71-1.el6.i686替换为同版本后在安装mysql。 b.创建需要下载rpm软件包的目录 [root@CentOS ~]# cd / [root@CentOS /]# mkdir tools [root@CentOS /]# cd tools/ [root@CentOS tools]# tar xf MySQL-5.6.27-1.linux_glibc2.5.i386.rpm-bundle.tar [root@CentOS tools]# ll 总用量 607688 -rw-r--r--. 1 root root 311132160 11月 15 20:51 MySQL-5.6.27-1.linux_glibc2.5.i386.rpm-bundle.tar -rw-r--r--. 1 7155 wheel 22940013 9月 22 00:32 MySQL-client-5.6.27-1.linux_glibc2.5.i386.rpm -rw-r--r--. 1 7155 wheel 4193230 9月 22 00:32 MySQL-devel-5.6.27-1.linux_glibc2.5.i386.rpm -rw-r--r--. 1 7155 wheel 113074786 9月 22 00:32 MySQL-embedded-5.6.27-1.linux_glibc2.5.i386.rpm -rw-r--r--. 1 7155 wheel 88299856 9月 22 00:33 MySQL-server-5.6.27-1.linux_glibc2.5.i386.rpm -rw-r--r--. 1 7155 wheel 2372993 9月 22 00:33 MySQL-shared-5.6.27-1.linux_glibc2.5.i386.rpm -rw-r--r--. 1 7155 wheel 5368256 9月 22 00:33 MySQL-shared-compat-5.6.27-1.linux_glibc2.5.i386.rpm -rw-r--r--. 1 7155 wheel 74877142 9月 22 00:34 MySQL-test-5.6.27-1.linux_glibc2.5.i386.rpm c.开始逐个安装 [root@CentOS tools]# rpm -ivh MySQL-server-5.6.27-1.linux_glibc2.5.i386.rpm warning: MySQL-server-5.6.27-1.linux_glibc2.5.i386.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY Preparing... ########################################### [100%] 1:MySQL-server ########################################### [100%] warning: user mysql does not exist - using root warning: group mysql does not exist - using root 2015-11-15 20:52:37 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated.

You will find that password in '/root/.mysql_secret'. ##为MySQL的数据库的root的用户生成了一个随机的秘密,请到/root/.mysql_secret里去找密码。 You must change that password on your first connect, no other statement but 'SET PASSWORD' will be accepted. See the manual for the semantics of the 'password expired' flag. Also, the account for the anonymous user has been removed. In addition, you can run: /usr/bin/mysql_secure_installation which will also give you the option of removing the test database. This is strongly recommended for production servers. See the manual for more instructions.
