Memcached on MAC
Memcached on MAC
Many years had gone since I used memcached. Even the official website is changed to this>
http://memcached.org/downloads
1. Check and Update the Memcached
Just download the latest files.
>wget http://memcached.org/files/memcached-1.4.20.tar.gz
>cd memcached-1.4.20
>./configure --prefix=/Users/carl/tool/memcached-1.4.20
Error Message:
checking for libevent directory... configure: error: libevent is required. You can get it from http://www.monkey.org/~provos/libevent/
Solution:
>wget http://cloud.github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz
>./configure
>make
>sudo make install
It solve the problem.
>./configure --prefix=/Users/carl/tool/memcached-1.4.20
>make
>make install
>sudo ln -s /Users/carl/tool/memcached-1.4.20 /opt/memcached-1.4.20
>sudo ln -s /opt/memcached-1.4.20 /opt/memcached
Start the Server
>memcached -d -m 50 -p 11211 -u carl -l 0.0.0.0
>memcached -d -m 50 -p 11212 -u carl -l 0.0.0.0
>memcached -d -m 50 -p 11213 -u carl -l 0.0.0.0
2. Configure and Put Haproxy in front of memcached
I add the configuration some as follow>
listen memcached_local_cluster 127.0.0.1:11210
#配置TCP模式
mode tcp
#balance url_param userid
#balance url_param session_id check_post 64
#balance hdr(User-Agent)
#balance hdr(host)
#balance hdr(Host) use_domain_only
#balance rdp-cookie
#balance leastconn
#balance source
//ip
#简单的轮询
balance roundrobin
#memcached集群节点配置
server memcached1 127.0.0.1:11211 check inter 5000 rise 2 fall 2
server memcached2 127.0.0.1:11212 check inter 5000 rise 2 fall 2 backup
