An example of Redis's installation, use, and expansion of Redis in PHP and implementation of the Redis operation in PHP

1, download the source package redis-2.8.21.tar.gz, and upload it to the specified directory /urs/src, and then unzip it:

[Email protected] src]# TAR-XVF redis-2.8.21.tar.gz

Enter the extracted directory and execute the following command to specify the installation directory as /urs/local/redis:

[Email protected] src]# CD redis-2.8.21

[[email protected] redis-2.8.21]# make Prefix=/usr/local/redis Install

After you have successfully installed Redis, you can See a bin directory in/usr/local/redis that includes the following files:

[Email protected] ~]# cd/usr/local/redis/bin/

[[email protected] bin]# ls

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

2. Add the redis boot script to the service:

In the /etc/rc.d/init.d directory, create a file called redis(description:/etc/rc.d/init.d/ The script in the directory will be executed when the system starts, and then add the following to the file:

[Email protected] ~]# Vim/etc/init.d/redis

#!/bin/bash

# Init file for Redis

# Chkconfig:-80 12

# Description:redis Daemon

# Processname:redis

# config:/etc/redis.conf

# Pidfile:/var/run/redis.pid

Source/etc/init.d/functions

Bin= "/usr/local/bin"

Config= "/etc/redis/redis.conf"

Pidfile= "/var/run/redis.pid"

# # Read Configuration

[-R "$SYSCONFIG"] && source "$SYSCONFIG"

Retval=0

Prog= "Redis-server"

desc= "Redis Server"

Start () {

If [-e $PIDFILE];then

echo "$desc already running ..."

Exit 1

Fi

Echo-n $ "Starting $desc:"

Daemon $BIN/$prog $CONFIG

Retval=$?

Echo

[$RETVAL-eq 0] && touch/var/lock/subsys/$prog

Return $RETVAL

}

Stop () {

Echo-n $ "Stop $desc:"

Killproc $prog

Retval=$?

Echo

[$RETVAL-eq 0] && rm-f/var/lock/subsys/$prog $PIDFILE

Return $RETVAL

}

Restart () {

Stop

Start

}

Case "$" in

Start

Start

;;

Stop

Stop

;;

Restart

Restart

;;

Condrestart)

[-e/var/lock/subsys/$prog] && restart

Retval=$?

;;

Status

Status $prog

Retval=$?

;;

*)

echo $ "Usage: $ {Start|stop|restart|condrestart|status}"

Retval=1

Esac

Exit $RETVAL

Copy the profile redis.conf from the extracted redis directory to /etc/redis/redis.conf ( Note the The path in the Redis startup script is the same )

[Email protected] ~]# Mkdir/etc/redis

[Email protected] ~]# cp/usr/src/redis-2.8.21/redis.conf/etc/redis/redis.conf

Then add redis to the enrollment service:

[Email protected] ~]# chkconfig--add Redis

[[email protected] ~]# chkconfig Redis on

[Email protected] ~]# chkconfig--list Redis

Redis 0:off 1:off 2:on 3:on 4:on 5:on 6:off

To restart redis:

[Email protected] ~]# service Redis restart

Stop Redis Server: [OK]

Starting Redis Server: [OK]

To see if the startup was successful:

[Email protected] ~]# Ps-ef | grep Redis

Root 2984 1 0 13:40? 00:00:00/usr/local/bin/redis-server 0.0.0.0:6379

Root 2989 2444 0 13:40 pts/1 00:00:00 grep redis

Modify /etc/redis/redis.conf, set up the redis process as the daemon, and specify a password :

[Email protected] ~]# vim/etc/redis/6379.conf

Daemonize Yes//daemonize: Whether to run in the next station daemon mode

Requirepass 20082009// Set Password to 20082009

After Setup, you will need to restart Redis for the settings to take effect:

[Email protected] ~]# service Redis restart

Modify the environment variable file to add the following:

Vim/etc/profile

#set Redis Path

Export Redis_home=/usr/local/redis

Export Path=${redis_home}/bin:${path}

make it effective immediately by Source/etc/profile

3, call redis-cli command for simple operation (note whether to start password Authentication):

[Email protected] ~]# REDIS-CLI

127.0.0.1:6379> Ping

(Error) Noauth Authentication required.

127.0.0.1:6379> auth 20082009 // need to enter a password

Ok

127.0.0.1:6379> Ping

PONG

127.0.0.1:6379> Set name LeBron James

(Error) ERR syntax error

127.0.0.1:6379> set name "LeBron James" /// string with spaces need to be added ""

Ok

127.0.0.1:6379> Get Name

"LeBron James"

127.0.0.1:6379> Set name Lebronjames

Ok

127.0.0.1:6379> Get Name

"Lebronjames"

127.0.0.1:6379>

4. expand redisin PHP:

Download a php extension phpredis Source package phpredis-2.2.4.tar.gz, upload it to the server at the specified location, Unzip it and then go to the extracted directory:

TAR-XVF phpredis-2.2.4.tar.gz

CD phpredis-2.2.4

generating Configure configuration files with phpize

[Email protected] phpredis-2.2.4]#/usr/local/php/bin/phpize

Then execute the following command:

[Email protected] phpredis-2.2.4]#/configure--with-php-config=/usr/local/php/bin/php-config

[[email protected] phpredis-2.2.4]# make && make install

To configure PHP support Phpredis, add the following in the php.ini file:

Vim/usr/local/php/lib/php.ini

extension=/usr/local/php/lib/php/extensions/no-debug-non-zts-20121212/redis.so

Then restart the nginx,php-fpm and redisseparately:

Service Nginx Restart

Service PHP-FPM Restart

Service Redis Restart

View phpinfo (), shown below, indicating that php extended Redis was successful:

A simple example of the PHP operation redis :

<?php   $redis = new Redis ();   $redis->connect (' 127.0.0.1 ', ' 6379 ') or Die ("Could not-to-connect to Redis"); or the specific host IP address line   $redis->set ("Test", "PHP handle Redis");   Var_dump ($redis->get (' Test '));   echo "<br/>";   $redis->del (' test ');   Delete Assignment   var_dump ($redis->get (' Test '));  >

Output Result:

From the results can be seen, Redis redis.conf The password is configured in the file redis redis.conf REQUIREPASS 20082009   #requirepass  20082009 redis : service redis restart

Execute the php file again, showing the following results, indicating that php operation Redis succeeded:
