在centos7，使用ls -l /etc/rc.loacl可以看到如下结果
+
角色                        主机名                                                            IP1              IP2     
−
lrwxrwxrwx. 1 root root 13 7月  31 22:02 /etc/rc.local -> rc.d/rc.local
 
  
−
可以看到上面的执行结果是显示有执行权限的，
+
7000  7001              01                  192.168.10.211   
−
但是当使用ls -l /etc/rc.d/rc.loacl的时候却可以看到如下结果
+
7002  7003              02                  192.168.10.212     
−
-rw-r--r--. 1 root root 730 Sep 27 05:38 /etc/rc.d/rc.local
+
7004  7005              03                  192.168.10.213     
−
/etc/rc.loacl所链接的文件是没有执行权限的，
+
</pre>
−
所以在启动的时候rc.local中写的命令得不到执行，
+
 
−
因此需要手动添加执行权限给/etc/rc.d/rc.loacl</pre>

 +
redis-trib.rb check 10.3.10.140:7001

−
注意：指定用户执行的脚本（程序）目录，该用户必须有管理该脚本（程序）目录（文件）的权限。
+
结果如下  16384个槽都分配到了 节点
  
−
最好将该脚本（程序）目录的所有权给该用户：
+

##**********************上面是老的
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
redis_install_dir=/data/apps/redis
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
redis_install_dir=/data/apps/redis
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

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：不建议

 
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

#非交互
redis_install_dir=/data/apps/redis
echo "${redis_install_dir}/bin/redis-server ${redis_install_dir}/redis_cluster/7004/redis_7004.conf
${redis_install_dir}/bin/redis-server ${redis_install_dir}/redis_cluster/7005/redis_7005.conf">${redis_install_dir}/redis_cluster/run

chmod +x ${redis_install_dir}/redis_cluster/run && bash ${redis_install_dir}/redis_cluster/run
chmod  +x /etc/rc.d/rc.local
echo "${redis_install_dir}/redis_cluster/run"  >>/etc/rc.d/rc.local #把变量替换为值

#交互
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?
