centos 6.7 搭建redis 主从服务
环境部署：redis master（zkdb1）：192.168.16.210
redis slave：192.168.16.211
安装部署：
#创建一个软件安装目录
# mkdir /home/softwares
# cd /home/softwares/
#下载软件包，同时解压安装
# wget http://download.redis.io/releases/redis-3.0.7.tar.gz
# tar -xvf redis-3.0.7.tar.gz-C /usr/local/
# cd /usr/local/redis-3.0.7/
# make PREFIX=/usr/local/redis7 install
#mkdir /opt/redis307 #创建一个redis 的配置文件目录
# cd /opt/redis307
# cp /usr/local/redis-3.0.7/redis.conf /opt/redis307/
# ./bin/redis-server /opt/redis307/redis.conf ##启动redis 服务
2、内核以及其他调整
添加如下两行
#/etc/sysctl.conf
net.core.somaxconn =8192
vm.overcommit_memory=1
#将下面三行写入到redis配置文件中
#echo 'rename-command FLUSHALL ""' >> redis.conf
#echo 'rename-command FLUSHDB ""' >> redis.conf
#echo 'rename-command KEYS ""' >> redis.conf
配置文件
vim /opt/redis307/redis.conf
port6000 ##更改端口
save 900 1
save 300 10000## 更改配置
save 60200000
dbfilename dump.rdb
slave-read-only yes##更改为yes
dir /opt/redis307/dbdata ## redis 数据存放目录，但该目录需要手工创建
appendonly yes
maxclients 30000
appendfsync everysec
appendfilename "appendonly.aof"
logfile "/tmp/redis307.log"
timeout 0

需要在两台redis配置文件中填写
vim /etc/profile
export PATH=/usr/local/redis7/bin:$PATH
source /etc/profile
验证：
主
redis-cli -p 6000
创建一个set keyvalus （创建一个key后面跟一个值）
get key
从
redis-cli -p 6000
get 该文件
