centos 6.7 搭建redis 主從服務

環境部署：

 redis master（zkdb1）：192.168.16.210

 redis slave  ：192.168.16.211

安裝部署：

#創建一個軟件安裝目錄

[root@zkdb1 ~]# mkdir /home/softwares
[root@zkdb1 ~]# cd /home/softwares/

#下載軟件包，同時解壓安裝
[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 #創建一個redis 的配置文件目錄

[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 ##啓動redis 服務
 2、內核以及其他調整
添加如下兩行

#/etc/sysctl.conf

net.core.somaxconn =8192
vm.overcommit_memory=1

#將下面三行寫入到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  ##更改爲yes
dir /opt/redis307/dbdata ## redis 數據存放目錄，但該目錄需要手工創建
appendonly yes
maxclients 30000  
appendfsync everysec
appendfilename "appendonly.aof"
logfile "/tmp/redis307.log"
timeout 0

需要在兩臺redis配置文件中填寫

vim /etc/profile

export PATH=/usr/local/redis7/bin:$PATH

source /etc/profile
驗證：
主
redis-cli -p 6000
創建一個set key  valus （創建一個key後面跟一個值）
get key
從 
redis-cli -p 6000
get 該文件
