批量执行工具之pssh

pssh是一个python编写的工具，它比ansible更轻量级。支持命令的批量执行、文件批量拷贝。

• pssh 在多个主机上并行运行命令
• pscp 把文件并行复制到多个主机上
• prsync 通过rsync协议把文件高效并行复制到多个主机上
• pslurp 把文件并行地从多个远程主机复制到中心主机上
• pnuke 并行地在多个远程主机上杀死进程

1、pssh安装

# 安装setuptools包，如果安装了跳过
wget http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz --no-check-certificate
tar -xf setuptools-0.6c11.tar.gz
cd setuptools-0.6c11
python setup.py build
python setup.py install
# 安装pssh
cd -
wget  http://www.theether.org/pssh/pssh-1.4.3.tar.gz
cd pssh-1.4.3/
python setup.py install

　　

2、pssh

[root@node1]# pssh
Usage: pssh [OPTIONS] -h hosts.txt prog [arg0] ..

  -h --hosts   hosts file (each line "host[:port] [user]")
  -l --user    username (OPTIONAL)
  -p --par     max number of parallel threads (OPTIONAL)
  -o --outdir  output directory for stdout files (OPTIONAL)
  -e --errdir  output directory for stderr files (OPTIONAL)
  -t --timeout timeout (secs) (-1 = no timeout) per host (OPTIONAL)
  -O --options SSH options (OPTIONAL)
  -v --verbose turn on warning and diagnostic messages (OPTIONAL)
  -P --print   print output as we get it (OPTIONAL)
  -i --inline  inline aggregated output for each server (OPTIONAL)

Example: pssh -h nodes.txt -l irb2 -o /tmp/foo uptime

　　

3、pscp

[root@node1 ~]# pscp
Usage: pscp [OPTIONS] -h hosts.txt local remote

  -r --recursive recusively copy directories (OPTIONAL)
  -h --hosts     hosts file (each line "host[:port] [login]")
  -l --user      username (OPTIONAL)
  -p --par       max number of parallel threads (OPTIONAL)
  -o --outdir    output directory for stdout files (OPTIONAL)
  -e --errdir    output directory for stderr files (OPTIONAL)
  -t --timeout   timeout (secs) (-1 = no timeout) per host (OPTIONAL)
  -v --verbose   turn on warning and diagnostic messages (OPTIONAL)
  -O --options   SSH options (OPTIONAL)

Example: pscp -h hosts.txt -l irb2 foo.txt /home/irb2/foo.txt

　　

4、prsync

要使用此命令，主机上必须要有rsync命令，否则执行不成功。

[root@node1 ~]# prsync
Usage: prsync [OPTIONS] -h hosts.txt local remote

  -r --recursive recusively copy directories (OPTIONAL)
  -a --archive   use rsync -a (archive mode) (OPTIONAL)
  -z --compress  use rsync compression (OPTIONAL)
  -h --hosts     hosts file (each line "host[:port] [login]")
  -l --user      username (OPTIONAL)
  -p --par       max number of parallel threads (OPTIONAL)
  -o --outdir    output directory for stdout files (OPTIONAL)
  -e --errdir    output directory for stderr files (OPTIONAL)
  -t --timeout   timeout (secs) (-1 = no timeout) per host (OPTIONAL)
  -v --verbose   turn on warning and diagnostic messages (OPTIONAL)
  -O --options   SSH options (OPTIONAL)

Example: prsync -r -h hosts.txt -l irb2 foo /home/irb2/foo

　　

5、pslurp

[root@node1 ~]# pslurp
Usage: pslurp [OPTIONS] -h hosts.txt -o outdir remote local

  -r --recursive recusively copy directories (OPTIONAL)
  -L --localdir  output directory for remote file copies
  -h --hosts     hosts file (each line "host[:port] [login]")
  -l --user      username (OPTIONAL)
  -p --par       max number of parallel threads (OPTIONAL)
  -o --outdir    output directory for stdout files (OPTIONAL)
  -e --errdir    output directory for stderr files (OPTIONAL)
  -t --timeout   timeout (secs) (-1 = no timeout) per host (OPTIONAL)
  -v --verbose   turn on warning and diagnostic messages (OPTIONAL)
  -O --options   SSH options (OPTIONAL)

Example: pslurp -h hosts.txt -L /tmp/outdir -l irb2 
         /home/irb2/foo.txt foo.txt

　　

6、pnuke

[root@node1 ~]# pnuke
Usage: pnuke [OPTIONS] -h hosts.txt pattern

  -h --hosts   hosts file (each line "host[:port] [user]")
  -l --user    username (OPTIONAL)
  -p --par     max number of parallel threads (OPTIONAL)
  -o --outdir  output directory for stdout files (OPTIONAL)
  -e --errdir  output directory for stderr files (OPTIONAL)
  -t --timeout timeout (secs) (-1 = no timeout) per host (OPTIONAL)
  -v --verbose turn on warning and diagnostic messages (OPTIONAL)
  -O --options SSH options (OPTIONAL)

Example: pnuke -h hosts.txt -l irb2 java
