NOTE
redis5 用redis-cli创建整个redis集群(redis5以前的版本集群是依靠ruby脚本redis-trib.rb实现

创建节点

#第一台：192.168.10.211 #here
redis_install_dir=/data/apps/redis
 mkdir -p ${redis_install_dir}
cd ${redis_install_dir} 
mkdir -p redis_cluster
cd redis_cluster
mkdir data 7000 7001

#cp /root/src/redis-5.0.5/redis.conf  ${redis_install_dir}/redis_cluster
#cd  /home/apps/redis/redis_cluster
#cp redis.conf 7000/redis_7000.conf
#mv redis.conf  7001/redis_7001.conf


#第2台：192.168.10.212

mkdir -p ${redis_install_dir}
cd ${redis_install_dir} 
mkdir -p redis_cluster
cd redis_cluster
mkdir data 7002 7003

#cp /root/src/redis-5.0.5/redis.conf  .
#cp  redis.conf 7002/redis_7002.conf
#mv redis.conf  7003/redis_7003.conf


#第3台：192.168.10.213

mkdir -p ${redis_install_dir}
cd ${redis_install_dir} 
mkdir -p redis_cluster
cd redis_cluster
mkdir data 7004 7005
#cp /root/src/redis-5.0.5/redis.conf  .
#cp redis.conf 7004/redis_7004.conf
#mv redis.conf 7005/redis_7005.conf

修改配置文件(三台机器6个配置)

note  日志在系统那  因为我们配置文件没指定 /var/log/redis/

ls /home/apps/redis/redis_cluster/data/
appendonly-7000.aof  dump_7000.rdb  nodes_7000.conf
appendonly-7001.aof  dump_7001.rdb  nodes_7001.conf
# 生成在这里了  /home/apps/redis/redis_cluster/data/nodes_7000.conf  nodes_7001.conf

配置建议加上这个  下面这些配置还加上的 
# appendfsync always
appendfsync everysec
# appendfsync no

创建集群

注意：在任意一台上运行 不要在每台机器上都运行，一台就够了
#要开通端口  firewalld
#在geany 有: 格式可能有点不对 要注意 
redis-cli --cluster create --cluster-replicas 1 192.168.10.211:7000 192.168.10.211:7001 192.168.10.212:7002 192.168.10.212:7003 192.168.10.213:7004  192.168.10.213:7005
#--replicas  1  表示 自动为每一个master节点分配一个slave节点    上面有6个节点，程序会按照一定规则生成 3个master（主）3个slave(从)

测试通过了

添加redis集群密码

方式一：修改所有Redis集群中的redis.conf文件加入

 
# NOTE   还是这个办法好  不然可能有些 没加载到配置文件去呢 
masterauth passwd123 
requirepass passwd123 
说明：这种方式需要重新启动各节点

方式二：进入各个实例进行设置 就是所有节点：

 
redis-cli -c -h 10.3.10.141 -p 7001
#好像不能一起执行
config set masterauth 36DbRGvv 
config set requirepass 36DbRGvv 
auth  36DbRGvv
config rewrite 

添加redis集群密码 一开始忘记加-c 导致 143 两个都加不上了  redis本身的密码这样就有了

-a 后 再执行命令就再 auth ， 而如果是进入后 auth password 要每次 都再验证一下密码 麻烦


开机自己启动

vi /apps/redis/redis_cluster/run

/apps/redis/bin/redis-server /home/apps/redis/redis_cluster/7004/redis_7004.conf
/apps/redis/bin/redis-server /home/apps/redis/redis_cluster/7005/redis_7005.conf

chmod  +x  /apps/redis/redis_cluster/run
chmod +x /etc/rc.d/rc.local

 vi  /etc/rc.d/rc.local
/apps/redis/redis_cluster/run

开启关闭

redis-cli -a xxx -c -h 192.168.0.60 -p 8001 shutdown  #集群cluster_state变成了fail状态?

原因 有一个台redis的机器 空间100%
