Three: Otter- -otter-node Installation Installation Configuration

1. Preparation Before Installation

Before installation, we need to configure the management console in the manager node information, otherwise ndoe nodes can not join manage
Step 1: Click on the machine management, zookeeper management

Step 2: Configure zookeeper address, typing
172.18.165.118:2181,172.18.165.119:2181,172.18.165.120:2181

Step 3: Add node

After successfully adding the following

We can see that the node number is 1, the state is not started. Here, the end of the preparatory work

2. Install node

#mkdir otter-node
#tar xf node.deployer-4.2.17.tar.gz -C otter-node
# mv otter-node /data/services/

Download the installation file attached to the first document, binary decompression can.

2. Configuration node of 1

#vim /data/services/otter-node/conf/otter.properties
otter.nodeHome = ${user.dir}/../
otter.htdocs.dir = ${otter.nodeHome}/htdocs
otter.download.dir = ${otter.nodeHome}/download
otter.extend.dir= ${otter.nodeHome}/extend
otter.zookeeper.sessionTimeout = 60000
otter.communication.payload = 8388608
otter.communication.pool.size = 10
otter.manager.address = 172.18.165.118:1099

Only you need to modify manager to address

6. The configuration nid 2

#echo 1 > /data/services/otter-node/conf/nid

nid configuration is a configuration corresponding to the ID number ready before, this step must be configured correctly, otherwise abnormal.

7. Start

#sh /data/services/otter-node/bin/startup.sh

8. Verify

#taif -f /data/services/otter-node/logs/node/cat node.log 
OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=128m; support was removed in 8.0
2019-06-27 20:21:02.701 [main] INFO  com.alibaba.otter.node.deployer.OtterLauncher - INFO ## the otter server is running now ......

This time, we can see that, node01 has become a start state

9. Repeat disposed node02, node03

We need three node configuration node status success, and remember node is different from the configuration as follows node3

节点2：
#echo 2 > /data/services/otter-node/conf/nid
节点3：
#echo 3 > /data/services/otter-node/conf/nid

manger before the start of the interface:

After manger interface start:

Here, we successfully installed the entire otter, if you will configure, has been normal use.
