python安装redis模块_安装redis及python redis模块

第一部分：安装redis

mkdir /usr/local/redis

cd /usr/local/src

wget http://download.redis.io/releases/redis-2.8.12.tar.gz

tar xzf redis-2.8.12.tar.gz

ln -s redis-2.8.12 redis

cd redis

make PREFIX=/usr/local/redis CFLAGS="-march=x86-64" install

上面7步指令，完成了redis的安装。

安装redis成功后，你将可以在/usr/local/redis看到一个bin的目录，里面包括了以下文件：

redis-benchmark  redis-check-aof  redis-check-dump  redis-cli  redis-server

第二部分：将redis做成一个服务

1.复制脚本到/etc/rc.d/init.d目录

cp /usr/local/src/redis/utils/redis_init_script /etc/rc.d/init.d/redis

2、如果这时添加注册服务

chkconfig --add redis

redis服务不支持chkconfig

为此，我们需要更改redis脚本。

3、更改redis脚本

备份原来的脚本

mv /etc/rc.d/init.d/redis /etc/rc.d/init.d/redis.bak

把redis脚本更改为如下内容

vim /etc/rc.d/init.d/redis

#!/bin/sh

#chkconfig: 2345 80 90

# Simple Redis init.d script conceived to work on Linux systems

# as it does use of the /proc filesystem.

REDISPORT=6379

EXEC=/usr/local/redis/bin/redis-server

CLIEXEC=/usr/local/redis/bin/redis-cli

PIDFILE=/var/run/redis_${REDISPORT}.pid

CONF="/etc/redis/${REDISPORT}.conf"

case "$1" in

start)

if [ -f $PIDFILE ]

then

echo "$PIDFILE exists, process is already running or crashed"

else

echo "Starting Redis server..."

$EXEC $CONF &

fi

;;

stop)

if [ ! -f $PIDFILE ]

then

echo "$PIDFILE does not exist, process is not running"

else

PID=$(cat $PIDFILE)

echo "Stopping ..."

$CLIEXEC -p $REDISPORT shutdown

while [ -x /proc/${PID} ]

do

echo "Waiting for Redis to shutdown ..."

sleep 1

done

echo "Redis stopped"

fi

;;

*)

echo "Please use start or stop as first argument"

;;

esac

4、将redis配置文件拷贝到/etc/redis/${REDISPORT}.conf

mkdir /etc/redis

cp /usr/local/src/redis/redis.conf /etc/redis/6379.conf

以上操作完成后，即可注册yedis服务：

chkconfig --add redis

赋予redis的权限

chmod 777 /etc/init.d/redis

service redis start

第三，将Redis的命令所在目录添加到系统参数PATH中

1、修改profile文件：

vi /etc/profile 文件，在最后行添加下面一条命令:

export PATH="$PATH:/usr/local/redis/bin"

应用这个文件：

. /etc/profile

2、这样就可以直接调用redis-cli的命令了

$ redis-cli

第四，安装python redis模块

[root@Python_learn ~]# /usr/local/src

[root@Python_learn src]#  wget --no-check-certificate https://pypi.python.org/packages/source/r/redis/redis-2.8.0.tar.gz

[root@Python_learn src]# tar -zvxf redis-2.8.0.tar.gz

[root@Python_learn src]# ln -s redis-2.8.0 python-redis

[root@Python_learn python-redis]# python setup.py install

已安装完成

测试

[root@Python_learn python-redis]# python
