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

[root@zkdb1 ~]# mkdir /home/softwares
[root@zkdb1 ~]# cd /home/softwares/
#下载软件包，同时解压安装
[root@zkdb1 softwares]# wget http://download.redis.io/releases/redis-3.0.7.tar.gz
[root@zkdb1 softwares]# tar -xvf redis-3.0.7.tar.gz -C /usr/local/
[root@zkdb1 redis7]# cd /usr/local/redis-3.0.7/
[root@zkdb1 redis7]# make PREFIX=/usr/local/redis7 install
[root@zkdb1 redis7]#mkdir /opt/redis307 #创建一个redis 的配置文件目录

[root@zkdb1 redis7]# cd /opt/redis307
[root@zkdb1 redis7]# cp /usr/local/redis-3.0.7/redis.conf /opt/redis307/
[root@zkdb1 redis7]# ./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
[root@zkdb1 redis7]#echo 'rename-command FLUSHALL ""' >> redis.conf
[root@zkdb1 redis7]#echo 'rename-command FLUSHDB ""' >> redis.conf
[root@zkdb1 redis7]#echo 'rename-command KEYS ""' >> redis.conf
配置文件
vim /opt/redis307/redis.conf
port 6000 ##更改端口
save 900 1
save 300 10000 ## 更改配置
save 60 200000
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
##启动redis 服务

redis 从配置如下：

5 内核以及其他调整
添加
[root@localhost redis-3.0.7]# vi /etc/sysctl.conf
net.core.somaxconn =8192
vm.overcommit_memory=1

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
#更改端口
port 6000
更改数字
save 900 1
save 300 10000
save 60 200000
dbfilename dump.rdb
slave-read-only yes
####添加
dir /opt/redis307/dbdata
## 改yes
appendonly yes
## 改数字
maxclients 30000
appendfsync everysec
appendfilename "appendonly.aof"
logfile "/tmp/redis307.log"
timeout 0
slaveof 192.168.16.210 6000 ## 从加入这一行主的ip

redis shutdown ok
[root@zkdb1 redis307]# vim /etc/rc.d/rc.local
/etc/init.d/redis start
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 key valus （创建一个key后面跟一个值）
get key
从
redis-cli -p 6000
get 该文件
