python1.下載安裝
wget http://www.memcached.org/files/memcached-1.5.3.tar.gz tar -zxvf memcached-1.5.3.tar.gz cd memcached-1.5.3 ./configure --prefix=/data/program/memcached make && make install
2.啟動memcache
./memcached -d -u root -l 127.0.0.1 -m 50 -p 11211 -c 512 -P /data/program/memcached/logs/memcached.pid
參數:
-u 運行身份
-p 指定端口號(默認11211)
-m 指定最大使用內存大小(默認64MB)
-t 線程數(默認4)
-l 連接的IP地址, 默認是本機
-d 以後臺守護進程的方式啟動
-c 最大同時連接數,默認是1024
-P 制定memecache的pid文件
-h 打印幫助信息
3.連接測試
[root@huangzp3 bin]# telnet 127.0.0.1 11211 Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. add test 1 0 5 hello STORED
4.memcache集群的操作
4.1下載api模塊python-memcached
wget https://pypi.python.org/packages/f7/62/14b2448cfb04427366f24104c9da97cf8ea380d7258a3233f066a951a8d8/python-memcached-1.58.tar.gz
linux環境:
tar python-memcached-1.58.tar.gz cd python-memcached-1.58 python setup.py install
參考鏈接:https://www.cnblogs.com/xiao1/p/5858967.html
4.2啟動
./memcached -d -u root -p 11211 ./memcached -d -u root -p 11212 ./memcached -d -u root -p 11213
例子:
#!/usr/bin/env python import memcache # 初始化一個memcache客戶端對象,端口權重分別為1:2:1,開啟錯誤debug顯示 mc = memcache.Client([("192.168.2.230:11211",1),("192.168.2.230:11212",2),("192.168.2.230:11213",1)],debug=True) mc.set("name","huangzhenping") print(mc.get("name")) mc1 = memcache.Client(["192.168.2.230:11211"],debug=True) print(mc1.get("name")) mc2 = memcache.Client(["192.168.2.230:11212"],debug=True) print(mc1.get("name")) mc3 = memcache.Client(["192.168.2.230:11213"],debug=True) print(mc3.get("name"))
運行結果:
