Redis_3.2.4 主从部署
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}

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
