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 ....

restart()

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

}
case "\$1" in

*)
echo "Usage: \$SCRIPTNAME {start|stop|restart}" >&2
exit 1

esac
exit 0
