批量执行工具PSSH详解

-L:指定从远程主机拷贝文件放置的目录，拷贝/root/expect.sh文件，并将其重命名为test1.
如果拷贝目录需要使用-r参数：

[root@localhost ~]# pslurp -h /etc/pssh_hosts -L /tmp/ /root/expect.sh test1 
[1] 10:44:55 [FAILURE] web1.jiajie.com 22 Received error code of 1
[2] 10:44:56 [FAILURE] web3.jiajie.com 22 Received error code of 1
[3] 10:44:56 [SUCCESS] web2.jiajie.com 22
[root@localhost ~]# ll /tmp/web2.jiajie.com/
总用量 4
-rw-r--r-- 1 root root 139 10月 17 10:44 test1
[root@localhost ~]# pslurp -r -h /etc/pssh_hosts -L /tmp/ /root/shell.sh      test2

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

prsync的主要作用是通过rsync协议将文件或目录从本地主
机同步到远程多个主机上。

[root@localhost ~]# prsync -h /etc/pssh_hosts -a -r /root/shell.sh /tmp
[1] 11:33:26 [SUCCESS] web3.jiajie.com 22
[2] 11:33:26 [SUCCESS] web1.jiajie.com 22
[3] 11:33:27 [SUCCESS] web2.jiajie.com 22

-r:递归复制。

-a:保持文件的属性不变

-z:压缩文件，一般不推荐。

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

pnuke的主要作用是在远程多主机上并行杀掉某一进程，
相当于killall命令。可以直接使用pssh 来传递killall命令，这里就不做介绍了。
