Linuxでtelenetのインストールとmemcachedの状態を調べる方法
1.telenetをインストール
#yum install telnet-server
#yum install telnet
#vi /etc/xinetd.d/telnet
service telnet
{
flags = REUSE
socket_type = stream
wait = no
user = root
server = /usr/sbin/in.telnetd
log_on_failure += USERID
disable = yes
}
xinetd起動
#/etc/init.d/xinetd restart
memcached起動
#/usr/local/memcached/bin/memcached -d -c 10240 -m 1024 -u root
2.状態の確認
#echo stats | nc localhost 10210
#ps -ef|grep memcached
memcached停止
#kill -9 pid
# telnet 127.0.0.1 10210
