Install the redis service and phpredis extension in linux

: This article describes how to install the redis service and phpredis extension in linux. For more information about PHP tutorials, see. More please support: http://www.webyang.net/Html/web/article_174.html

I. redis installation

Download, extract and compile Redis:

 
 

  
  
$ wget http://download.redis.io/releases/redis-3.0.4.tar.gz
  
  
$ tar xzf redis-3.0.4.tar.gz
  
  
$ cd redis-3.0.4
  
  
$ make
 
 

The binaries that are now compiled are available in the src directory. Run Redis:

 
 

  
  
$ src/redis-server
 
 

You can interact with Redis using the built-in client:

 
 

  
  
$ src/redis-cli
 
 

Redis> set foo bar
OK
Redis> get foo
"Bar"

II. php extension:
More versions: http://pecl.php.net/package/redis

 
 

  
  
Wget http://pecl.php.net/get/redis-2.2.5.tgz
  
  
# Decompress
  
  
Tar zxvf redis-2.2.5.tgz
  
  
# Enter the installation directory
  
  
Cd redis-2.2.5
  
  
/Usr/local/php/bin/phpize
  
  
# Configuration
  
  
./Configure -- with-php-config =/usr/local/php/bin/php-config
  
  
# Compile and install
  
  
Make & make install
 
 

After the installation is complete, the following installation path appears:
/Usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/
Configure php support
# Edit the configuration file and add the following content in the last line

 
 

  
  
vim /usr/local/php/etc/php.ini 
  
  
extension="redis.so"
 
 

At this time, phpinfo () can see the redis extension.
Small example of redis:

 
 

  
  
$ Redis = new redis ();
  
  
$ Test = $ redis-> connect ('2017. 0.0.1 ', 127 );
  
  
Var_dump ($ test );
  
  
 
  
  
$ Result = $ redis-> set ('test', "webyang.net ");
  
  
Var_dump ($ result); // result: bool (true)
  
  
 
  
  
$ Result = $ redis-> get ('test ');
  
  
Var_dump ($ result); // result: string (11) "webyang.net"
 
 

The reason for this is that the company uses Alibaba's RDS and occasionally gets stuck when concurrency is high. The CPU is directly 6000. RDS is 12 GB of memory, with a maximum IOPS of 2000 and a maximum connection count, we are far from reaching this number, so we are considering a redisQueuePlay, put some things that do not need to be executed in real timeQueue. I wanted to directly execute the command after the data is saved for several minutes.QueueI did not expect a good method. I can only write a script in linux to run it once every few minutes. In fact, this is not very intelligent, and some resources are wasted, do you have any good ideas? Brainstorm ~

The above describes how to install the redis service and php redis extension in linux, including the queue content, and hope to be helpful to friends who are interested in the PHP Tutorial.
