"Linux database" Redis installation configuration

One, Redis configuration

1. Download and install

$ wget http://download.redis.io/releases/redis-2.8.17.tar.gz$ tar xzf redis-2.8.17.tar.gz$ cd redis-2.8.17$ make

$ make Install

Redis's executable files are put to/usr/local/bin by default.

2. Download the configuration file and init startup script:

wget Https://github.com/ijonas/dotfiles/raw/master/etc/init.d/redis-server
wget https://github.com/ijonas/dotfiles/raw/master/etc/redis.conf
sudo mv Redis-server/etc/init.d/redis-server
sudo chmod +x/etc/init.d/redis-server
sudo mv redis.conf/etc/redis.conf
3. Initialize user and log path

Before starting Redis for the first time, it is recommended that you create a separate user for Redis and create a new data and log directory

sudo useradd Redis
sudo mkdir-p/var/lib/redis
sudo mkdir-p/var/log/redis
sudo chown Redis.redis/var/lib/redis
sudo chown Redis.redis/var/log/redis
4, set up their own initiative to boot. Shut down and shut down voluntarily

sudo update-rc.d redis-server defaults
5. Start Redis:

Sudo/etc/init.d/redis-server start

6. Start the Client connection:

$ redis-cli
Redis> set Foo Bar
Ok
Redis> get foo

"Bar"

Address: Http://redis.io/download

Assuming that the Redis service is not turned on, the following error may occur, for example :

Uncaught exception ' redisexception ' with message ' Redis server went away

CentOS command to start Redis service

cd/usr/local/bin/

sudo./redis-server

Now running PHP redis.php will error CALSS Redis not found

Need to install a phpredis extension

Download: http://dl.dbank.com/c0u193fjey#

/usr/local/php/bin/phpize

./configure--with-php-config=/usr/local/php/bin/php-config

Make && make install

Vi/etc/php.d/redis.ini

Extension=/usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/redis.so

This step depends on your own PHP compilation parameters--with-config-file-scan-dir=/etc/php.d this to decide where to add redis.so.

The most important step in Phpredis extended installation:

sudo vi/usr/local/php/lib/php.ini

Then look for:/extension

When you find a location such as the following. Join the extension=redis.so

              Extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613"
extension=memcache.so
extension=memcached.so
extension=pdo_mysql.so
extension=censoring.so
extension=curl.so
extension=zlib.so
extension=mysql.so
extension=gd.so
extension=triefind.so
extension=kwordfilter.so
extension=xhprof.so
extension=pcntl.so
extension=redis.so

Finally restart the Redis service

cd/usr/local/bin/

sudo./redis-server

PHP clears Redis database

//删除当前数据库中的全部Key$redis->flushdb ();//delete key from all databases $redis->flushall ();
