Tutorial for installing and configuring the Redis database on the CenOS system

1: install redis

wget http://redis.googlecode.com/files/redis-2.6.14.tar.gz
tar zxvf redis-2.6.14.tar.gz
cd redis-2.6.14
make PREFIX=/usr/local/redis install

2: configure redis

Use the default configuration file and modify it slightly

1. Customary practice, configuration files in the source installation folder, easy to manage it

mkdir /usr/local/redis/etc/
cp redis-2.6.14/redis.conf /usr/local/redis/etc/

2. Modify the configuration files/usr local redis/etc/redis conf
(1)Redis does not run as a daemon by default, and can be modified with this configuration item to enable the daemon with yes

daemonize yes

(2) close the connection when the client is idle for a long time. If it is specified as 0, it means to close the function

timeout 300

(3) specify the redis log

logfile /var/log/redis.log

(4) specify the local database storage directory

dir /data/redis/redis_db

3. Start redis

/usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf

3: test redis

1 demonstrates a simple set key, get key operation...

Please install php redis client, under the specific installation reference (https: / / github com/nicolasff/phpredis)

<?php
$redis = new Redis();
try{
  $redis->connect('127.0.0.1',6379);
}
catch (Exception $e){
  die("Cannot connect to redis server:".$e->getMessage() );
}

$redis->set('name','budong');
echo $redis->get('name');
?>

Output budong and the installation is successful.
2. The playability of redis is too much. The operation and maintenance must check the operation information of redis, as follows:

[root@Cache ~]# /usr/local/redis/bin/redis-cli 
redis 127.0.0.1:6379> INFO

Some of the results are as follows:

redis_version:2.4.7
redis_git_sha1:00000000
redis_git_dirty:0
arch_bits:64
multiplexing_api:epoll
