CentOS下安装memcached(yum 方式)

服务器环境:CentOS 5
人比较懒，所以用yum方式安装.命令行下执行
# yum install memcached
报错：
rpmdb: Lock table is out of available locker entries
rpmdb: Unknown locker ID: b7d
error: db4 error(22) from db->close
rpm 包管理器挂了。
运行以下命令修复
# cd /var/lib/rpm
# rm -rf __db.00*
# rpm --rebuilddb
好了，再次运行

# yum install memcached
更新速度慢得要死，所以，先装了一下 yum的镜像
# yum install fastestmirror
这下爽多了。
再执行
# yum install memcached
顺利装好 memcached
# rpm -qa|grep memcached
可以查看一下 memcached 版本号
启动 memcached
# memcached -d -u root
然后
# telnet localhost 11211
顺利出现
Escape character is '^]'.
