Memcached and Redis Installation

Memcached

1. Build up the LNMP

2. Installing dependent Packages
Yum Install-y libevent-devel

3. Installing memcached
$ cd/usr/local/src
$ wget http://memcached.org/files/memcached-1.4.33.tar.gz
$ TAR-ZXVF memcached-1.4.33.tar.gz
$ CD memcached-1.4.33
$./configure--prefix=/usr/local/memcached && make && make install

Open service
Cd/usr/local/memcached/bin
./memcached-u www-d
-p TCP port, default is 11211, can not be set
-m maximum memory, in megabytes.
-u specifies that the user, if currently root, needs to use this parameter to specify the user
-D Daemon (daemon)

4. Installing libmemcached
$ wget https://launchpad.net/libmemcached/1.0/1.0.18/+download/libmemcached-1.0.18.tar.gz
$ tar xvzf libmemcached-1.0.18.tar.gz

$ make && make install

5. Installing PHP-MEMCACHED-PHP7
wget http://www.memcached.org/files/memcached-1.4.33.tar.gz
Phpize
./configure--with-php-config=/usr/local/php7/bin/php-config
--with-libmemcached-dir=/usr/local/libmemcached/
Make && make install
Add the path from the previous step to the PHP configuration file:/usr/local/php7/etc/php.ini
extension= "/usr/local/php7/lib/php/extensions/no-debug-non-zts-20151012/memcached.so"
Restart Php:service php-fpm Restart

6. Using memcached
Create new object: Memcached
Add Server: Addserver
To add a key-value pair: Set
Get values based on key values: get
Delete a key-value pair: Delete
Increment specified value: increment
Minus the specified value: Decrement
Clear all caches: flush

7. Set session to save with memcached
Vi/usr/local/php7/etc/php/ini
Session.save_handler=memcached
Session.save_path= "127.0.0.1:11211"

Redis installation Uses

1.redis Installation:
Description
1) also a storage service similar to memcached's key-value mechanism
2) A non-relational database NoSQL
3) Www.redis.io www.redis.cn
Characteristics:
1) Ability to persist data storage memcache cannot
2) value supports more data types

Installation: Redis
wget http://download.redis.io/releases/redis-3.2.8.tar.gz
1) Unzip
TAR-ZXVF redis-3.2.8.tar.gz
2) move
Cp-r Redis-3.2.8/usr/local/redis
3) Installation
Make install

Service:
After the installation is complete, there are two service programs in the/USR/LOCAL/REDIS/SRC directory
Client: REDIS-CLI
Service side: Redis-server
Service test:./redis-server
1) You need to specify the boot configuration file
2) Default configuration/usr/local/redis/redis.conf
To add an environment variable:
Vi/etc/profile
Export path= $PATH:/USR/LOCAL/REDIS/SRC
Source/etc/profile

Boot up:
1) copy config file
Cd/usr/local/redis
CP redis.conf redis_6379.conf
2) Edit Profile
Daemonize Yes # Run as daemon (background run)
3) Copy startup script file
CD utils
CP redis_init_script redis_init_script_6379
4) Edit the startup script file Redis_init_ script_6379
Exec=/usr/local/redis/src/redis-server #服务端路径
Cliexec=/usr/local/redis/src/redis-cli #客户端路径
conf=/usr/local/redis/redis_6379.conf #配置文件路径
5) test the startup script (can be viewed via PS and connected with REDIS-CLI)
./redis_init_script_ 6379 Start
6) Modify boot file/etc/rc.local
Add/usr/local/redis/utils/redis_init_script_6379 start
7) The Redis service will start automatically the next time you turn on

Service test:
1) View process
PS aux | grep Redis
2) using a client connection
Cd/usr/local/redis/src
Connection parameters
-H: Specify host
-P: Specify port number
-A: Specify password
./redis-cli
127.0.0.1:6379>ping
PONG
3) default is no password using password two ways
1. Single entry effective via command configuration
Set Password: config requirepass 123456
Get password: config get requirepass
Authorized use: Auth 123456
2. Permanent entry into force
1.VI redis_6379.conf
2. Cancel the ' Requirepass ' line comment after the password is written
Requirepass 123456
Description: Password is enabled without password and can be connected without permission action

Client actions

Common commands:
Ping to see if the server allows
Quit to close the current connection
Auth
Select: Choose Library 0-15 A total of 16 default use 0
FLUSHDB: Delete the current library
Flushall: Delete all databases
DEL: Delete key
EXISTS: Check if key exists

Data type:
String: The most basic data type is the same as the memcached Key-value
Setting: Set key value
Get: Get key
Hash (hash): is a set of key-value pairs suitable for storing objects
Settings: Hmset user:1 name xiaoming password 123456 Level 2
Get all information: Hgetall user:1
Get a single message: Hget user:1 name
List: Sort by Insertion order to add an element to the head of the list (to the left) or to the tail (to the right)
Left-hand Press: Lpush key value1 [value2 ...]
Range Display: Lrange Key strat stop
Number of displays: Llen key
Left popup: Lpop
Right Press in: Rpush
Right popup: Rpop
Collection (SET): Data in a string type without a consolidated collection is unique
Add data: Sadd key value1 [value2 ...]
Display data: Smembers key
Total displayed: SCard key
Random removal: Spop key [count] randomly removes a
Ordered set (zset:sorted set)
Unlike set, each element is associated with a double-type fraction.
Redis is a small-to-large ordering of members in a collection by fractions
Add data: Zadd key score Value
Display data: Zrange key start stop
Total displayed: Zcard key
Display range: Zcount key start stop
Display Number: Zrank key member
Show score: Zscore Key member

PHP Operation Redis:

(Error: Can ' t find PHP headers in/usr/include/php
Yum install php-devel)
1. Installing PHP Extensions
$ wget https://github.com/phpredis/phpredis/archive/2.2.4.tar.gz
$ CD phpredis-2.2.7
$/usr/bin/phpize #phpize路径, available which phpize commands to view
$./configure--with-php-config=/usr/bin/php-config #/usr/bin/php as php path, Ibid. phpize
$ make && make install

2. Modify the PHP configuration file php.ini
Vi/usr/local/php7/etc/php.ini
Add the path to the previous step
Extension=/usr/local/php7/lib/php/extensions/no-debug-non-zts-20151012/redis.so

3. Restart PHP-FPM
Service PHP-FPM Restart

4. Test the expansion library for Success (Phpinfo ())

/usr/lib64/php/modules/redis.so
