1.3.1 establishment of redis cluster
1. Open Bin1 / redis Conf search 😕 Change cluster to: cluster enabled yes
/Port modify port number
2. Copy 6 bin s as the redis interface image
Remember to open redis server redis.com in the bin directory conf
Modify redis Conf port number forced saving: wq!
3. Enter this folder: cd /opt/module/redis-4.0.9/src/
To find redis trib rb
4. Copy redis
cp redis-trib.rb /usr/local/redis/cluster/
5. Return
cd /usr/local/redis/cluster/
6.redis.gma3.2.1 path:
cd /home/hadoop/
gem install redis
7. Implementation
./redis-trib.rb create --replicas 1 192.168.2.101:6379 192.168.2.101:6380 192.168.2.101:6381 192.168.2.101:6382 192.168.2.101:6383 192.168.2.101:6384
8. The script starts the cluster
#!/bin/bash
for PORT in {1..6}
do
cd bin${PORT}

cd enters hadoop user
1. Convert the of root user to other users: (remember to execute it in root user)
chown hadoop:hadoop elasticsearch-6.2.3.tar.gz (file name)
2. Enter a YML file VIM elasticsearch. In the config folder of elasticsearch-6.2.3 yml
Paste in the following paragraph

3. Configure JVM options
Change to 512M according to the memory of your virtual machine
4. Enter the bin directory to execute/ elasticsearch
Report a problem
[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
[2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
solve the problem
1. Switch to root first
2. Switch to VIM / etc / security / limits conf
3. Add to terminal
* soft nofile 65536 * hard nofile 65536
4. Path: VIM / etc / sysctl conf
add to
vm.max_map_count=655360
5. test
sysctl -p [root@hdp01 elasticsearch-6.2.3]# ulimit -hu -bash: ulimit: -h: invalid option ulimit: usage: ulimit -SHacdefilmnpqrstuvx [root@hdp01 elasticsearch-6.2.3]# ulimit -Hu 7185
6. Switch back to the hadoop user and execute su hadoop
./elasticsearch
7. Visit: http://192.168.2.101:9200/
