redis集群安装

下载安装redis(所有节点)

wget http://download.redis.io/releases/redis-4.0.11.tar.gz
tar zxvf redis-4.0.11.tar.gz
cd redis-4.0.11
make
cd src/
make install

配置redis

node1

mkdir -p /data/redis/{7000,7001}/data
mkdir -p /usr/local/redis-cluster/bin
mkdir -p /usr/local/redis-cluster/7000
cp ../redis.conf  /usr/local/redis-cluster/7000/

#修改以下配置
vim /usr/local/redis-cluster/7000/redis.conf
bind 10.241.0.10   #绑定本机IP
daemonize yes       #开启后台运行
dir /data/redis/7000/data       #数据存放路径
port 7000           #监听端口
pidfile /var/run/redis_7000.pid #pid文件
logfile /var/log/redis_7000.log #log文件
cluster-enabled yes             #打开注释
cluster-config-file nodes.conf  #打开注释
cluster-node-timeout 15000      #打开注释
appendonly yes                  #开启持久化

#7001节点配置
cp  -rf /usr/local/redis-cluster/7000/  /usr/local/redis-cluster/7001/
sed -i 's/7000/7001/g' /usr/local/redis-cluster/7001/redis.conf

#将配置文件copy到其他的节点
scp -r /usr/local/redis-cluster/{7000,7001}  root@10.241.0.11:/usr/local/redis-cluster/
scp -r /usr/local/redis-cluster/{7000,7001}  root@10.241.0.12:/usr/local/redis-cluster/

node2

mkdir -p /data/redis/{7000,7001}/data
mkdir -p /usr/local/redis-cluster/bin
cp mkreleasehdr.sh redis-benchmark redis-check-aof redis-cli redis-server redis-trib.rb /usr/local/redis-cluster/bin
sed -i 's/10.241.0.10/10.241.0.11/g' /usr/local/redis-cluster/7000/redis.conf 
sed -i 's/10.241.0.10/10.241.0.11/g' /usr/local/redis-cluster/7001/redis.conf

node3

mkdir -p /data/redis/{7000,7001}/data
mkdir -p /usr/local/redis-cluster/bin
cp mkreleasehdr.sh redis-benchmark redis-check-aof redis-cli redis-server redis-trib.rb /usr/local/redis-cluster/bin
sed -i 's/10.241.0.10/10.241.0.12/g' /usr/local/redis-cluster/7000/redis.conf 
sed -i 's/10.241.0.10/10.241.0.12/g' /usr/local/redis-cluster/7001/redis.conf

启动redis(所有节点)

/usr/local/redis-cluster/bin/redis-server /usr/local/redis-cluster/7000/redis.conf
/usr/local/redis-cluster/bin/redis-server /usr/local/redis-cluster/7001/redis.conf

ps -ef|grep redis
root      3079     1  0 00:26 ?        00:00:00 /usr/local/redis-cluster/bin/redis-server 10.241.0.10:7000 [cluster]
root      3243     1  0 00:28 ?        00:00:00 /usr/local/redis-cluster/bin/redis-server 10.241.0.10:7001 [cluster]

netstat -nplt|grep redis-server

iptables放行

#如开iptables,需注意,端口放行, 注意17000,17001也要放行,不然加入不到集群
-A INPUT -p tcp -m tcp --dport 7000 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 7001 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 17000 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 17001 -j ACCEPT

配置集群(只在node1操作)

安装ruby

wget https://cache.ruby-lang.org/pub/ruby/2.2/ruby-2.2.7.tar.gz
tar xvf ruby-2.2.7.tar.gz
cd ruby-2.2.7
./configure --prefix=/usr/local/ruby-2.2.7
make && make install
ln -s /usr/local/ruby-2.2.7/bin/ruby /usr/bin/ruby
ln -s /usr/local/ruby-2.2.7/bin/gem /usr/bin
ruby -v
gem -v

使用gem安装redis集群依赖

gem install redis

创建集群

如集群都设置了密码,需要修该
/usr/local/ruby-2.2.7/lib/ruby/gems/2.2.0/gems/redis-4.0.1/lib/redis/client.rb 文件中的
Password 参数将密码写入到这里,

/usr/local/redis-cluster/bin/redis-trib.rb create --replicas 1 10.241.0.10:7000 10.241.0.10:7001 10.241.0.11:7000 10.241.0.11:7001  10.241.0.12:7000 10.241.0.12:7001
