1.下载

从官网上下载了SUSE版本的MySQL包MySQL-5.5.20-1.sles11.x86_64.tar。

SUSE是装在VMware里的，通过ftp把tar包传到SUSE的/srv/ftp/upload中。

2.安装

解压tar包：

# cd /srv/ftp/upload

# tar -xf MySQL-5.5.20-1.sles11.x86_64.tar

解出了6个rpm文件：

MySQL-client-5.5.20-1.sles11.x86_64.rpm

MySQL-devel-5.5.20-1.sles11.x86_64.rpm

MySQL-embedded-5.5.20-1.sles11.x86_64.rpm

MySQL-server-5.5.20-1.sles11.x86_64.rpm

MySQL-shared-5.5.20-1.sles11.x86_64.rpm

MySQL-test-5.5.20-1.sles11.x86_64.rpm

把server和client装上：

# rpm -ivh MySQL-server-5.5.20-1.sles11.x86_64.rpm

# rpm -ivh MySQL-client-5.5.20-1.sles11.x86_64.rpm

这时直接输入mysql命令会提示ERROR 2002 (HY000):Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

是因为mysql服务未启动，要执行:

# /etc/init.d/mysql start

来启动mysql。
