Mesos集群：2个Linux agent和1个Windows agent

Posted 2022-06-09 yangzhenping

先上图哈：

一、Mesos master和slave（其实就是agent）搭建在一台机器上：

过程中遇到两个问题：

1. mesos failed to connect to 5050
I was having the same issues and what fixed it for me was the zookeeper configuration. In my case I was using the EC2 public IP Address rather than the private one. Once I changed the /etc/mesos/zk file to zk://<private IP>:2181/mesos I was able to connect without the constant error messages. In other words, zookeeper was reporting to be running in one IP and mesos-master was trying to connect using a different IP.

vi /etc/hosts
service zookeeper restart
service mesos-slave restart
service mesos-master restart
service marathon restart

2. Failed to perform recovery: Incompatible agent info detected.
rm -rf /var/log/mesos/*.*
rm -f /var/mesos/meta/slaves/latest
cat /var/log/mesos/mesos-slave.ERROR

root@omi64ub16-dev1:~# cat /var/log/mesos/mesos-slave.ERROR  
Log file created at: 2017/11/06 22:46:05

To remedy this do as follows:
Step 1: rm -f /var/lib/mesos/meta/slaves/latest
        This ensures agent doesn't recover old live executors.
Step 2: Restart the agent.

二、加另一台Linux机器作为agent：

Setup Mesos Multi-node Cluster on Ubuntu:
https://techpolymath.com/2014/08/28/setup-mesos-multi-node-cluster-on-ubuntu/

echo 10.226.174.148 | sudo tee /etc/mesos-slave/ip
echo zk://10.226.210.177:2181/mesos | sudo tee /etc/mesos/zk
echo 10.226.174.148 | sudo tee /etc/mesos-slave/hostname
service mesos-slave restart

三、加另一台Windows机器作为agent：参考http://mesos.apache.org/documentation/latest/windows/

powershell命令：

cd c:\\

git clone https://git-wip-us.apache.org/repos/asf/mesos.git

cd mesos

mkdir build

cd build

cmake .. -G "Visual Studio 15 2017 Win64" -T "host=x64" -DENABLE_LIBEVENT=1

cmake --build .

src\\mesos-agent.exe --master=10.226.210.177:5050 --work_dir=C:\\ --launcher_dir=C:\\mesos\\build\\src --isolation=windows/cpu,filesystem/windows --hostname=10.226.157.145 --ip=10.226.157.145 --log_dir=C:\\mesos-log --runtime_dir=C:\\mesos-runtime

# --containerizers="docker, mesos"
