驗證是否可執行

/usr/local/repcached/bin/memcached -h

啓動 memcache

經過 repcached 安裝的 memcached 命令啓動 memcache 服務並實現 memcache 主備結構，其中-x 爲對方即主 memcache 的 IP， -X 爲本地啓動的用數據同步的端口：

server 1 相關操做：

/usr/local/repcached/bin/memcached -d -m 2048 -p 11211 -u root -c 2048 -x 172.24.77.243 -X 16000

server 2 相關操做：

/usr/local/repcached/bin/memcached -d -m 2048 -p 11211 -u root -c 2048 -x 172.24.77.241 -X 16000

鏈接到 memcache 驗證數據

yum install telnet -y

telnet 172.24.77.243 11211

set name 0 4

test

quit

telnet 172.24.77.241 11211
