Redis_3.2.4主从部署-创新互联

系统：Centos6.6x64

版本：redis-3.2.4

安装目录：/opt/

主：172.16.15.103

从：172.16.15.104

1,下载安装：

安装依赖：

# 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,内核修改配置

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

/sbin/sysctl -p

3, iptables/selinux及内核设置：

# cat /etc/sysconfig/iptables

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

4,创建数据日志目录

#mkdir -p redis/{log,data}

5,redis 主从配置

6,启动测试：

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

# ps-ef|grep redis

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

7,测试：

主服务103上执行创建：

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

    >set test 123456

从服务104上执行查看：

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

    >get test

性能测试

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

关闭服务

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

强制刷新数据到磁盘【Redis默认是异步写入磁盘的】

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

redis 资源信息数据统计查看： info

# redis-cli -h 127.0.0.1 -a passwd

    > info 

Redis 模糊搜索

 keys *

 select 2

删除所有以user开头的key 可以这样实现：

# redis-cli keys "user*"

1) "user1"

2) "user2"

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

(integer) 2

# 删除成功

# 批量删除匹配通配符的key用到了Linux中的管道和xargs参数：

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

# 如果需要制定数据库，需要用到 -n 数据库编号  参数，下面是删除2数据库中s开头的键：

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

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

# 如果redis-cli没有设置成系统变量，需要指定redis-cli的完整路径

＃　如：/opt/redis/redis-cli keys "*" | xargs /opt/redis/redis-cli del

# 删除当前数据库中的所有Key

flushdb

# 删除所有数据库中的key

flushall
