版本：redis-3.2.4

安裝目錄：/opt/

主：172.16.15.103

從：172.16.15.104

1,下載安裝：

安裝依賴(lài)：

# yum install gcc tcl ruby -y 

# wget http://download.redis.io/releases/redis-3.2.4.tar.gz

# tar xf redis-3.2.4.tar.gz

# mv redis-3.2.4 /opt/redis

# cd /opt/redis

# make 

# make test 

2,內(nèi)核修改配置

echo "vm.overcommit_memory=1" >> /etc/sysctl.conf

/sbin/sysctl -p

3, iptables/selinux及內(nèi)核設(shè)置：

# cat /etc/sysconfig/iptables 

-A INPUT -p tcp -m state --state NEW -m tcp --dport 6379 -j ACCEPT

4,創(chuàng)建數(shù)據(jù)日志目錄

#mkdir -p redis/{log,data}

5,redis 主從配置

# /opt/redis# nohup src/redis-server redis.conf &

# ps-ef|grep redis

# /usr/local/redis/bin/redis-cli ping

7,測(cè)試：

主服務(wù)103上執(zhí)行創(chuàng)建：

# /usr/local/redis/bin/redis-cli -h 172.16.15.103 -a 1qaz@WSX 

    >set test 123456

從服務(wù)104上執(zhí)行查看：

# /usr/local/redis/bin/redis-cli -h 172.16.15.104

    >get test

性能測(cè)試

# /usr/local/redis/bin/redis-benchmark

關(guān)閉服務(wù)

# /usr/local/redis/bin/redis-cli -p 6379 shutdown

強(qiáng)制刷新數(shù)據(jù)到磁盤(pán)【Redis默認(rèn)是異步寫(xiě)入磁盤(pán)的】

# /usr/local/redis/bin/redis-cli -p 6379 save

redis 資源信息數(shù)據(jù)統(tǒng)計(jì)查看： info

# redis-cli -h 127.0.0.1 -a passwd

Redis 模糊搜索

 keys *

 select 2 

刪除所有以u(píng)ser開(kāi)頭的key 可以這樣實(shí)現(xiàn)：

# redis-cli keys "user*"

1) "user1"

2) "user2"

# redis-cli keys "user*" | xargs redis-cli del

(integer) 2

# 刪除成功

# 批量刪除匹配通配符的key用到了Linux中的管道和xargs參數(shù)：

redis-cli keys "s*" | xargs redis-cli del 

# 如果需要制定數(shù)據(jù)庫(kù)，需要用到 -n 數(shù)據(jù)庫(kù)編號(hào)   參數(shù)，下面是刪除2數(shù)據(jù)庫(kù)中s開(kāi)頭的鍵：

redis-cli -n 2 keys "s*" | xargs redis-cli -n 2 del

redis-cli keys "*" | xargs redis-cli del  

# 如果redis-cli沒(méi)有設(shè)置成系統(tǒng)變量，需要指定redis-cli的完整路徑  

?！∪纾?opt/redis/redis-cli keys "*" | xargs /opt/redis/redis-cli del 

# 刪除當(dāng)前數(shù)據(jù)庫(kù)中的所有Key  

flushdb  

# 刪除所有數(shù)據(jù)庫(kù)中的key  

flushall
