 +
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

== 数据损坏重做 2020==
 
<pre>
 
<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

 +
 +
=== 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

 +
 +
 +
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

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

docker-compose

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 

Usage:
NOTE2020
docker-compose up -d

#要改的地方
bind   172.18.178.218 127.0.0.1

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

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

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

添加密码

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

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

源码手工

单独安装redis-cli

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

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

 
#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

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

redis client redis-tools or redis-cli


下载 解压源码
sudo make -j 9
sudo cp  src/redis-cli  /usr/bin/redis-cli


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?  不过要服务正常的情况下才行

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

断电后，node文件  nodes-7002.conf 内容中多了一个V 删除后正常

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

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

断电后 cluster损坏
