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

启动 memcache

通过 repcached 安装的 memcached 命令启动 memcache 服务并实现 memcache 主备结构,其中-x 为对方即主 memcache 的 IP, -X 为本地启动的用数据同步的端口:

server 1 相关操作:

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

server 2 相关操作:

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

连接到 memcache 验证数据

yum install telnet -y

telnet 172.24.77.243 11211

set name 0 4

test
