一．redis服務(wù)安裝配置

1.       下載解壓redis軟件包

目前成都創(chuàng)新互聯(lián)公司已為近1000家的企業(yè)提供了網(wǎng)站建設(shè)、域名、網(wǎng)站空間、網(wǎng)站托管、企業(yè)網(wǎng)站設(shè)計、衡南網(wǎng)站維護(hù)等服務(wù)，公司將堅持客戶導(dǎo)向、應(yīng)用為本的策略，正道將秉承"和諧、參與、激情"的文化，與客戶和合作伙伴齊心協(xié)力一起成長，共同發(fā)展。

# 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(tǒng)及你的配置下讀寫性能

|-- redis-check-aof    #更新日志檢查

|-- redis-check-rdb

|-- redis-cli     #Redis命令行操作工具，也可以用telnet根據(jù)純文本協(xié)議操作

|-- redis-sentinel -> redis-server

`-- redis-server   #Redis服務(wù)器的daemon啟動程序

3.       配置環(huán)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.       啟動關(guān)閉redis服務(wù)

# redis-server /application/redis/conf/redis.conf &          #啟動redis服務(wù)

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 # 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.

二．為PHP安裝redis客戶端擴(kuò)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
