Redis_3.2.4 主從部署

系統：Centos6.6x64

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：

# 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,內核修改配置

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

/sbin/sysctl -p

3, iptables/selinux及內核設置：

# cat /etc/sysconfig/iptables 

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

4,創建數據日志目錄

#mkdir -p redis/{log,data}

5,redis 主從配置

6,啟動測試：

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

# ps-ef|grep redis

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

7,測試：

主服務103上執行創建：

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

    >set test 123456

從服務104上執行查看：

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

    >get test

性能測試

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

關閉服務

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

強制刷新數據到磁盤【Redis默認是異步寫入磁盤的】

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

redis 資源信息數據統計查看： info

# redis-cli -h 127.0.0.1 -a passwd

    > info 

Redis 模糊搜索

 keys *

 select 2 

刪除所有以user開頭的key 可以這樣實現：

# 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：

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

# 如果需要制定數據庫，需要用到 -n 數據庫編號   參數，下面是刪除2數據庫中s開頭的鍵：

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

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

# 如果redis-cli沒有設置成系統變量，需要指定redis-cli的完整路徑  

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

# 刪除當前數據庫中的所有Key  

flushdb  

# 刪除所有數據庫中的key  

flushall
