Python连接Redis配置详解
操作环境： CentOS 5.4
操作步骤：
（一） 安装Redis:
[root@localhost /]# yum install redis Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: centos.ustc.edu.cn * epel: mirrors.yun-idc.com * extras: mirrors.yun-idc.com * updates: mirrors.yun-idc.com Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package redis.i386 0:2.4.10-1.el5 set to be updated --> Finished Dependency Resolution Dependencies Resolved ================================================================================ Package Arch Version Repository Size ================================================================================ Installing: redis i386 2.4.10-1.el5 epel 299 k Transaction Summary ================================================================================ Install 1 Package(s) Upgrade 0 Package(s) Total download size: 299 k Is this ok [y/N]: y Downloading Packages: redis-2.4.10-1.el5.i386.rpm | 299 kB 00:01 Running rpm_check_debug Running Transaction Test Finished Transaction Test Transaction Test Succeeded Running Transaction Installing : redis 1/1 Installed: redis.i386 0:2.4.10-1.el5 Complete!
（二）启动redis:
[root@localhost etc]# redis-server /etc/redis.conf [root@localhost etc]# ps -ef | grep redis root 17699 1 0 12:05 ? 00:00:00 redis-server /etc/redis.conf root 17762 17615 0 12:49 pts/1 00:00:00 grep redis
（三）用telnet连接并测试：
[root@localhost etc]# telnet localhost 6379 Trying 127.0.0.1... Connected to localhost.localdomain (127.0.0.1). Escape character is '^]'. set key1 4 +OK get key1 $1 4 set key2 hello +OK get key2 $5 hello quit +OK Connection closed by foreign host.
（四）安装python client:
[root@localhost etc]# easy_install redis Searching for redis Reading http://pypi.python.org/simple/redis/ Best match: redis 2.7.6 Downloading https://pypi.python.org/packages/source/r/redis/redis-2.7.6.tar.gz#md5=e975ea446c40046ef6dc41c98e41a4f8 Processing redis-2.7.6.tar.gz Running redis-2.7.6/setup.py -q bdist_egg --dist-dir /tmp/easy_install-v8JaAU/redis-2.7.6/egg-dist-tmp-6xgSQs zip_safe flag not set; analyzing archive contents... Adding redis 2.7.6 to easy-install.pth file Installed /usr/local/lib/python2.6/site-packages/redis-2.7.6-py2.6.egg Processing dependencies for redis Finished processing dependencies for redis
（五）测试：
[root@localhost etc]# python
