+
+1. ### 源码安装，版本redis-4.0.14
+
+   ```shell
+   wget http://download.redis.io/releases/redis-4.0.14.tar.gz
+   tar xzf redis-4.0.14.tar.gz
+   cd redis-4.0.14
+   make
+   ```
+
+2. ### 服务启动
+
+   ```shell
+   cd redis-4.0.14
+   # 启动服务端
+   src/redis-server
+   # 启动客户端
+   src/redis-cli
+   # 优雅关闭服务
+   src/redis-cli shutdown save
+   ```
+
+3. ### 集群部署
+
+   ```shell
+   # 节点服务启动
+   /data/bin/redis/redis/src/redis-server /data/bin/redis/cluster/conf/9901/redis.conf
+   /data/bin/redis/redis/src/redis-server /data/bin/redis/cluster/conf/9902/redis.conf
+   /data/bin/redis/redis/src/redis-server /data/bin/redis/cluster/conf/9903/redis.conf
+   /data/bin/redis/redis/src/redis-server /data/bin/redis/cluster/conf/9904/redis.conf
+   /data/bin/redis/redis/src/redis-server /data/bin/redis/cluster/conf/9905/redis.conf
+   /data/bin/redis/redis/src/redis-server /data/bin/redis/cluster/conf/9906/redis.conf
+   # 集群启动
+   /data/bin/redis/redis/src/redis-trib.rb create --replicas 1 172.16.0.32:9901 172.16.0.32:9902 172.16.0.32:9903 172.16.0.32:9904 172.16.0.32:9905 172.16.0.32:9906
+   # 连接client
+   /data/bin/redis/redis/src/redis-cli -c -h 172.16.0.32 -p 9901 -a wisdomCity@redis2019
+   # 优雅关闭节点服务
+   /data/bin/redis/redis/src/redis-cli -c -h 172.16.0.32 -p 9901 -a wisdomCity@redis2019 shutdown
+   /data/bin/redis/redis/src/redis-cli -c -h 172.16.0.32 -p 9902 -a wisdomCity@redis2019 shutdown
+   /data/bin/redis/redis/src/redis-cli -c -h 172.16.0.32 -p 9903 -a wisdomCity@redis2019 shutdown
+   /data/bin/redis/redis/src/redis-cli -c -h 172.16.0.32 -p 9904 -a wisdomCity@redis2019 shutdown
+   /data/bin/redis/redis/src/redis-cli -c -h 172.16.0.32 -p 9905 -a wisdomCity@redis2019 shutdown
+   /data/bin/redis/redis/src/redis-cli -c -h 172.16.0.32 -p 9906 -a wisdomCity@redis2019 shutdown
+   # 查看redis节点信息
+   ps -ef | grep redis
+   # 带密码集群，修改以下文件，不知道路径的话可以执行查找命令 find / -name 'client.rb'
+   # 修改 password 对应的值
+   vi /var/lib/gems/2.5.0/gems/redis-4.1.3/lib/redis/client.rb
+   
+   
+   ```
+
+   
+
+4. ### 集群进入fail状态的必要条件
+
+   1. 某个主节点和所有从节点全部挂掉，我们集群就进入faill状态
+   2. 如果集群超过半数以上master挂掉，无论是否有slave，集群进入fail状态
+   3. 如果集群任意master挂掉,且当前master没有slave，集群进入fail状态
+
+5. 异常处理
+
+   ```
+   # 登陆
+   /data/bin/redis/redis/src/redis-cli -c -p 9902
+   # set时候出现以下错误
+   (error) CLUSTERDOWN The cluster is down
+   # 检查命令
+   /data/bin/redis/redis/src/redis-trib.rb check 127.0.0.1:9902
+   # 发现一下错误
+   [ERR] Not all 16384 slots are covered by nodes.
+   # 执行一下修复命令（实战没用）
+   /data/bin/redis/redis/src/redis-trib.rb fix 127.0.0.1:9902
+   ```
