openlava配置计算节点

下为开源版本openlava的安装和部署，LSF(LSF Community Edition)有社区版可用

---

安装配置（安装目录：/opt/openlava-4.0/）：

yum install  tcl-devel  # dependency
yum install ncurses-devel  #dependency
# 解压openlava-4.0.tar.gz  
tar -xzvf openlava-4.0.tar.gz  
# 进入安装包  
cd openlava-4.0  
# 编译安装，默认安装位置/opt/openlava-4.0/  
./configure  
make  
make install  
# 创建openlava账户  
useradd -r openlava  
# 拷贝config到安装目录  
cp -rf config/* /opt/openlava-4.0/etc/  
# 配置环境变量，更改文件权限或属主（若有多个节点，每个节点上都需要配置！）  
chown -R openlava:openlava /opt/openlava-4.0  
cp -rf /opt/openlava-4.0/etc/openlava /etc/init.d/  
cp -rf /opt/openlava-4.0/etc/openlava.* /etc/profile.d/  
chmod 755 /etc/init.d/openlava  
chmod 755 /etc/profile.d/openlava.*  
chown -R openlava:openlava /etc/init.d/openlava  
chown -R openlava:openlava /etc/profile.d/openlava.*  
# 执行  
chkconfig openlava on

以下是为集群添加负载节点配置实例

---

添加节点：

#每一个节点均要设置,并开启openlava service

# 创建openlava账户
useradd -r openlava
# 配置环境变量，更改文件权限和所属

cp -rf /public/openlava/openlava-4.0-releaseetc/openlava /etc/init.d/  
cp -rf /public/openlava/openlava-4.0-releaseetc/openlava.* /etc/profile.d/
chown -R openlava:openlava /public/openlava/openlava-4.0-release
chmod 755 /etc/init.d/openlava
chmod 755 /etc/profile.d/openlava.*
chown -R openlava:openlava /etc/init.d/openlava
chown -R openlava:openlava /etc/profile.d/openlava.*
# 执行
chkconfig openlava on

#开启该节点openlava：
service openlava start

#导入环境变量
source /etc/profile.d/openlava.sh

#测试openlava服务
lsid, lshosts, bhosts查看状态是否ok

 问题: 

• Failed in an LSF library call: Failed in sending/receiving a message: Connection reset by peer

  #Run:
  lsadmin reconfig
  badmin reconfig
  badmin mbdrestart

  refs: https://www.ibm.com/support/pages/bsub-command-fails-lsf-library-call-failed-sending-receiving-message

•  查看与切换节点状态（节点状态改变后，bhosts查看稍等下才会显示状态变化）

  /etc/init.d/openlava status  #查看节点状态
  /etc/init.d/openlava stop    #停止
  /etc/init.d/openlava restart #重启

• 配置文件在openlava安装路径下的etc目录
  • lsb.hosts：配置最大Jobs数
    • MXJ可大于核数，0状态为closed
  • lsf.cluster.openlava：主配置文件
  • lsf.users用户配置文件（提交任务数限制等）
  • 修改配置文件后需要运行：

    #Run:
    badmin reconfig

• batch system daemon not responding ... still trying batch system daemon not responding ... still trying
  • 参考：https://www.ibm.com/support/pages/lsf-cluster-not-responding-because-too-many-interactive-or-block-mode-jobs

    To enable and define the parameter, please follow these steps:
    
    1) In lsf.conf, find LSB_NUM_NIOS_CALLBACK_THREADS=<n>
    
    2) As "n" is the number of threads in the thread pool, you can start with value "4".
    
    3) Restart mbatchd by "badmin mbdrestart"
