redis-4.0.1安裝配置（CentOS 6.6）

一．redis服務安裝配置

1.        下載解壓redis軟件包

# wget http://download.redis.io/releases/redis-4.0.1.tar.gz

# tar zxvf redis-4.0.1.tar.gz

# cd redis-4.0.1

2.        編譯安裝redis

# make MALLOC=jemalloc

# make PREFIX=/application/redis-4.0.1 install

# ln -s /application/redis-4.0.1/ /application/redis

# tree /application/redis/bin/

/application/redis/bin/

|-- redis-benchmark   #Redis性能測試工具，測試redis在你的系統及你的配置下讀寫性能

|-- redis-check-aof    #更新日誌檢查

|-- redis-check-rdb

|-- redis-cli     #Redis命令行操做工具，也能夠用telnet根據純文本協議操做

|-- redis-sentinel -> redis-server

`-- redis-server   #Redis服務器的daemon啓動程序

3.        配置環境變量

# echo "export PATH=/application/redis/bin:$PATH" >>/etc/profile

# source /etc/profile

# redis-server --help

# mkdir /application/redis/conf

[root@wangning redis-4.0.1]# cp redis.conf  /application/redis/conf/

4.        啓動關閉redis服務

# redis-server /application/redis/conf/redis.conf &          #啓動redis服務

[1] 10047

[root@wangning redis-4.0.1]# 10047:C 26 Jul 15:19:17.150 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

10047:M 26 Jul 15:19:17.162 # WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.

10047:M 26 Jul 15:19:17.162 # Server initialized

10047:M 26 Jul 15:19:17.162 # WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.

10047:M 26 Jul 15:19:17.163 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.

10047:M 26 Jul 15:19:17.163 * Ready to accept connections

# ps -ef|grep redis

5.        鏈接redis服務測試

交互式用法

[root@wangning redis-4.0.1]# redis-cli

127.0.0.1:6379>

127.0.0.1:6379> help get

 

  GET key

  summary: Get the value of a key

  since: 1.0.0

  group: string

 

127.0.0.1:6379> help set

 

  SET key value [EX seconds] [PX milliseconds] [NX|XX]

  summary: Set the string value of a key

  since: 1.0.0

  group: string

 

127.0.0.1:6379> set no002 wangning

OK

127.0.0.1:6379> get no002

"wangning"

127.0.0.1:6379> quit

或者

[root@wangning redis-4.0.1]# telnet 127.0.0.1 6379

Trying 127.0.0.1...

非交互式用法

# redis-cli -h 127.0.0.1 -p 6379 set no002 wangning

# redis-cli -h 127.0.0.1 -p 6379 get no002

"wangning"

或者

# redis-cli set no002 wangning

# redis-cli get no002 

"wangning"

 

# redis-cli -h 10.0.0.21 -p 6379 info   #統計信息

 

二．爲PHP安裝redis客戶端擴展

# wget https://github.com/nicolasff/phpredis/archive/master.zip

# unzip master.zip

# cd phpredis-master/

# /application/php/bin/phpize

# ./configure  --with-php-config=/application/php/bin/php-config

# make

# make install

# echo "extension = redis.so" >>/application/php/lib/php.ini

# killall php-fpm

# /application/php/sbin/php-fpm
