==host 网络 要手工添加集群==
同样要用firewall etc 
要优化的地方    restart  已添加  



相关脚本和配置
https://github.com/evan886/redis/tree/master/redis-cluster-docker_host
<pre>
Usage:
NOTE2020
docker-compose up -d

#要改的地方
bind   172.18.178.218 127.0.0.1


批量替换 sed  
sed -i 's!old!new!' filename

 sed  -i 's!5.0.2-alpine!5.0.9-alpine!' docker-compose.yml
   
 sed -i 's!192.168.11.236!172.31.16.4!' *.conf

aliyu 不能 绑定外网NAT IP   bind 内网IP 然后 创建集群用 外网IP就可以了 

不然后
(error) CLUSTERDOWN Hash slot not served  cluster没起来 

#docker exec -it  node-7000  redis-cli -p 7000  --cluster create  10.25.196.78:7000     10.25.196.78:7001  10.25.196.78:7002  10.25.196.78:7003  10.25.196.78:7004  10.25.196.78:7005  --cluster-replicas 1

IP='192.168.10.193'
docker exec -it  node-7000  redis-cli -p 7000  --cluster create  $IP:7000     $IP:7001  $IP:7002  $IP:7003  $IP:7004  $IP:7005  --cluster-replicas 1


# #要改的地方 不要交互
echo 'masterauth passwd123d 
requirepass passwd123d' >>redis-7000.conf




check 

docker exec -it  node-7000  redis-cli -p 7000  -c   -h 483.284.7.34 -a passwd12Trttt3d




bind 要记得改为你要的IP  如果用0.0.0.0 那就不要127.0.0.1 
有问题多看log 目录 

#这里是母机的ip 如果是三台机器 那么就有 三个 IP 
docker exec -it  node-7000  redis-cli -p 7000  --cluster create  ip:7000     ip:7001  ip:7002  ip:7003  ip:7004  ip:7005  --cluster-replicas 1

docker exec -it  node-7000  redis-cli -p 7000  --cluster create --cluster-replicas 1 ip:7000     ip:7001  ip:7002  ip:7003  ip:7004  ip:7005 

三台母机的情形 就是每个docker-compose.yml 只启动两个 ，其它的删除就行了  201912

== 数据损坏重做 2020==
<pre>
内网的193机器  PHP老是搞坏，或者强行restart os   常常会有几个节点起不来 这时 只能重新做 cluster 

 data 目录下的mv 走或删除掉 
 conf 目录下的 先去掉密码  
 up -d 起所有节点 
 conf 用追加再添加回密码 
 docker-compose restart 起回所有的节点

### Redis Cluster evan##########################################
    redis-cluster:
      build: ./redis-cluster
      ports:
        - "${REDIS_CLUSTER_PORT_RANGE}:7000-7005"
      networks:
        - backend


cat  redis-cluster/Dockerfile  #注意 redis版本
FROM grokzen/redis-cluster:5.0.6
#FROM grokzen/redis-cluster:latest
LABEL maintainer="hareku <hareku908@gmail.com>"
</pre>

=== 添加密码===
<pre>
添加密码 可以进入容器里面直接添加 ，不过不够好 ，有空要 放到母机出来，有如我上面
004  7005  redis-cluster.tmpl	redis.tmpl  sentinel.tmpl
root@401a49002b88:/data# ls /redis-conf/700
7000/ 7001/ 7002/ 7003/ 7004/ 7005/ 
root@401a49002b88:/data# ls /redis-conf/7000/redis.conf 
/redis-conf/7000/redis.conf
root@401a49002b88:/data# tail /redis-conf/7000/redis.conf 
bind 0.0.0.0
port 7000
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes
dir /redis-data/7000


进入redis-cluster 容器 直接非交互  这里以7005 端口为例子 

redis-cli  -c  -h 127.0.0.1  -p 7005   config set masterauth 36DbRGvv66 
redis-cli  -c  -h 127.0.0.1  -p 7005   config set requirepass 36DbRGvv66 
redis-cli  -c  -h 127.0.0.1  -p 7005 auth  36DbRGvv66

redis-cli  -c  -h 127.0.0.1  -p 7005   -a 36DbRGvv66  config rewrite
redis-cli  -c  -h 127.0.0.1  -p 7005  config rewrite  # 最后这一步 有时得 加上密码 



Usage:  可以直接用物理机的ip  内网或者外网 

上次搞了几天 ，是忙晕了 不记得打开防火墙 7000-7005的端口
</pre>

=源码手工=
==单独安装redis-cli==
<pre>
debian 上可以单独安装 redis-cli 
但是rhel居然不行 只能编译一下  

三步曲后 make  -j  2 之后 ，copy 走这个 bin 文件就行了 
./src/redis-cli -c  /usr/bin/  #或者放 /usr/sbin  只有超级用户可以用到  如果其它用户要用 就不要放这里了 


redis cluster 执行脚本 不用老是一个一个的搞 麻烦   其实只要在三个主上执行就行了 你6个全执行也没事，反正是脚本的 

#!/bin/bash
##Usage  bash redisin.sh   你的redis脚本
redis-cli    -c  -h    172.31.22.218   -p 7000  -a hello   `cat $1`
redis-cli    -c  -h    172.31.22.218   -p 7001  -a hello   `cat $1`
#
redis-cli    -c  -h   172.31.16.135   -p 7002  -a hello   `cat $1` #$1 # del hello_list 


</pre>

==节点信息==
<pre>
角色                        主机名                                                             IP1               IP2

=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== 
<pre> 
#不要交互 
echo 'masterauth passwd123d 
requirepass passwd123d' >>redis-7000.conf



# 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
</pre>

==方式二：进入各个实例进行设置   就是所有节点：不建议==
<pre> 
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

redis 安装报错 jemalloc/jemalloc.h: No such file or directory

理上次编译残留文件，重新编译

make distclean  && make

导致出现这个错误的原因

　　错误的本质是我们在开始执行make 时遇到了错误（大部分是由于gcc未安装），然后我们安装好了gcc 后，我们再执行make ,这时就出现了jemalloc/jemalloc.h: No such file or directory。这是因为上次的

== Creating Server TCP listening socket *:6379: bind: No such file or directory==
问题描述

Creating Server TCP listening socket *:6379: bind: No such file or directory
解决思路

我这边检查之后发现Redis服务已经启动了

    redis-cli 去看是否能连接上，进的去执行 shutdown 就断开连接，重新执行就可以启动 如果可以的话 
    ps -ef | grep redis 查看服务是否已经启动，kill -9 PID 杀掉服务重新启动
