Redis Installation and PHP extensions

: Http://redis.io/download to download the latest version of the document.

1. Download and install

sudo wget http://download.redis.io/releases/redis-3.2.9.tar.gz

sudo tar-zxvf redis-3.2.9.tar.gz

sudo cd redis-3.2.9

sudo make

sudo make Prefix=/usr/local/redis install

2. Configuration

sudo mkdir/usr/local/redis/etc/

sudo vim/usr/local/redis/etc/redis.conf//write the following:

Daemonize Yes

Pidfile/usr/local/redis/var/redis.pid

Port 6379

Timeout 300

LogLevel Debug

Logfile/usr/local/redis/var/redis.log

Databases 16

Save 900 1

Save 300 10

Save 60 10000

Rdbcompression Yes

Dbfilename Dump.rdb

dir/usr/local/redis/var/

AppendOnly No

Appendfsync always

The following are the meanings of the main configuration parameters of redis.conf:

Daemonize: Whether to run daemon mode later

Pidfile:pid File Location

Port: Port number for listening

Timeout: Request time-out

Loglevel:log Information level

Logfile:log File Location

Databases: number of open databases

Save *: How often the snapshot is saved, the first * indicates how long, and the third * indicates how many times the write operation is performed. Snapshots are automatically saved when a certain number of writes are performed within a certain amount of time. You can set multiple conditions.

Rdbcompression: Whether to use compression

Dbfilename: Data Snapshot file name (only file name, excluding directory)

Dir: Save directory for Data snapshot (this is the directory)

AppendOnly: If the appendonlylog is turned on, each write will record a log, which will improve the data anti-risk ability, but affect the efficiency.

Appendfsync:appendonlylog How to sync to disk (three options, each write is forced to call Fsync, Fsync per second, do not call Fsync wait for the system to synchronize itself)

sudo mkdir/usr/local/redis/var/

sudo chmod 777/usr/local/redis/var/

The commands to start Redis are:

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

PS Axu |grep Redis

NETSTAT-TUNLP |grep Redis

Once the Redis service process is started, you can use the test client program REDIS-CLI to interact with the Redis service. Like what:

$ cd src$./Redis-Cliredis> SetFoo Barokredis> GetFoo"Bar"

PHP Installation Redis Extensions

The following operations need to be done in the downloaded Phpredis directory:

sudo wget http://pecl.php.net/get/redis-3.1.2.tgz

sudo tar-zxvf redis-3.1.2.tgz

CD redis-3.1.2

[Email protected] redis-3.1.2]$ sudo/usr/local/php/bin/phpize

Configuring for:

PHP Api version:20160303

Zend Module Api no:20160303

Zend Extension Api no:320160303

[email protected] redis-3.1.2]$ sudo./configure--with-php-config=/usr/local/php/bin/php-config

[[Email protected]er2 redis-3.1.2]$ sudo make

[[email protected] redis-3.1.2]$ sudo make install

Installing Shared extensions:/usr/local/php/lib/php/extensions/no-debug-non-zts-20160303/

[email protected] redis-3.1.2]$ sudo vim/usr/local/php/etc/php.ini

Add the following content:

Extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20160303" extension = Redis . So

Restart the PHP-FPM or Nginx after the installation is complete. View the phpinfo information to see the Redis extension.

Or

Create *.ini files under/usr/local/php/etc/conf.d/to make it easier to manage PHP extension modules

Mkidr/usr/local/php/etc/conf.d/redis.ini

Extension = redis.so

Systemctl Restart Php-fpm.service//restart PHP service

Connect to the Redis service

sudo vim/usr/local/nginx/html/2.php

< ? Connect to the local Redis service   

$redis Span style= "font-size:12px;font-family: ' Courier New '; Color:rgb (102,102,0); Background-color:rgb (251,251,251);" >= new Span style= "font-size:12px;font-family: ' Courier New '; Color:rgb (102,0,102); Background-color:rgb (251,251,251);" >redis ();   

$redis -Connect(' 127.0.0.1 ', 6379);   

Echo "Connection to server sucessfully" ; //See if the service is running

Echo"Server is running:" .$redis -Ping();?>

Curl localhost/2.php
