Redis 主从模式

系统：Centos6.6x64
安装目录：/usr/local/
主：192.168.100.103
从：192.168.100.104

,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..tar.gz
# mv redis-3.2. /opt/redis
# cd /opt/redis
# make
# make test
 
,内核修改配置
echo "vm.overcommit_memory=1" >> /etc/sysctl.conf
/sbin/sysctl -p
 
,iptables端口开发 selinux关闭设置：
# cat /etc/sysconfig/iptables
-A INPUT -p tcp -m state --state NEW -m tcp --dport  -j ACCEPT
 
,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 192.168.100.103 -a passwd set test 
 
从服务104上执行查看：
# /usr/local/redis/bin/redis-cli -h 192.168.100.104 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
