twemproxy memcach集群

1、安装memcached

yum install memcached python-memcached -y

sed -i ‘/MAXCONN/s/"1024"/"8192"/‘ /etc/sysconfig/memcached

sed -i ‘/CACHESIZE/s/"64"/"2048"/‘ /etc/sysconfig/memcached

sed -i "/OPTIONS/s/\"\"/\"-l $first_net_if_ip\"/" /etc/sysconfig/memcached

systemctl enable memcached.service

systemctl start memcached.service

2、安装twemproxy代理

cd /packet/

wget http://$yum_repo_server:8080/os-kilo-1/nutcracker-0.3.0.tar.gz

sleep 2

tar zxvf nutcracker-0.3.0.tar.gz

sleep 5

cd nutcracker-0.3.0/

./configure --prefix=/usr/local/twemproxy

sleep 30

make

sleep 10

make install

sleep 20

mkdir /usr/local/twemproxy/run /usr/local/twemproxy/conf/

cd /usr/local/twemproxy/conf/

cat >/usr/local/twemproxy/conf/nutcracker.yum << EOF

3、启动twemproxy服务

/usr/local/twemproxy/sbin/nutcracker -d -c /usr/local/twemproxy/conf/nutcracker.yum -p /usr/local/twemproxy/run/memproxy.pid -o /usr/local/twemproxy/run/memproxy.log

4、配置twemproxy的启动项及设置开机自启动

cat >/etc/rc.d/init.d/twemproxy <<EOF

#! /bin/sh

# chkconfig: 2345 10 90

# description: myservice ....

}

stop()

}

restart()

haproxy_pid=`cat \$PIDFILE`

kill \$haproxy_pid

\$DAEMON -d -c \$CONFIG -p \$PIDFILE -o \$PROGLOG

echo "."

}

case "\$1" in

*)

echo "Usage: \$SCRIPTNAME {start|stop|restart}" >&2

exit 1
