自动化运维工具-pssh工具安装配置及简单使用讲解

1、先决条件：安装pssh工具要求python版本大于2.4即可。安装pssh工具的主机针对远程主机需要配置免秘钥认证：ssh-keygen -t rsassh-copy-id [remotehost] 2、下载pssh工具安装介质：https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/parallel-ssh/pssh-2.3.1.tar.gz 3、安装pssh： tar -zxvf pssh-2.3.1.tar.gzcd pssh-2.3.1python setup.py install 安装完成后默认生成5个linux命令： Parallel ssh (pssh)Parallel scp (pscp)Parallel rsync (prsync)Parallel nuke (pnuke)Parallel slurp (pslurp) 4、pssh使用案例讲解： 1）pssh使用案例： pssh --help可以查看命令帮助文档。 $ pssh --helpUsage: pssh [OPTIONS] command [...] Options:   --version             show program's version number and exit   --help                show this help message and exit   -h HOST_FILE, --hosts=HOST_FILE                         hosts file (each line "[user@]host[:port]")   -H HOST_STRING, --host=HOST_STRING                         additional host entries ("[user@]host[:port]")   -l USER, --user=USER  username (OPTIONAL)   -p PAR, --par=PAR     max number of parallel threads (OPTIONAL)   -o OUTDIR, --outdir=OUTDIR                         output directory for stdout files (OPTIONAL)   -e ERRDIR, --errdir=ERRDIR                         output directory for stderr files (OPTIONAL)   -t TIMEOUT, --timeout=TIMEOUT                         timeout (secs) (0 = no timeout) per host (OPTIONAL)   -O OPTION, --option=OPTION                         SSH option (OPTIONAL)   -v, --verbose         turn on warning and diagnostic messages (OPTIONAL)   -A, --askpass         Ask for a password (OPTIONAL)   -x ARGS, --extra-args=ARGS                         Extra command-line arguments, with processing for                         spaces, quotes, and backslashes   -X ARG, --extra-arg=ARG                         Extra command-line argument   -i, --inline          inline aggregated output and error for each server   --inline-stdout       inline standard output for each server   -I, --send-input      read from standard input and send as input to ssh   -P, --print           print output as we get it      1）pssh简单案例： $ pssh -H hadoop@db02 -P datedb02: Thu Oct  5 23:56:25 CST 2017[1] 23:56:25 [SUCCESS] hadoop@db02 $ pssh -H hadoop@db02 -i date[1] 23:56:30 [SUCCESS] hadoop@db02Thu Oct  5 23:56:30 CST 2017   2）批量查看远程服务器负载： more remotehosts   db01db02db03db04 $ pssh -i -O "StrictHostKeyChecking=no" -h remotehosts "uptime"[1] 00:29:42 [SUCCESS] db02  00:29:42 up 1 day, 12:33,  3 users,  load average: 0.03, 0.02, 0.10[2] 00:29:42 [SUCCESS] db01  00:29:42 up 1 day, 12:33,  4 users,  load average: 0.02, 0.02, 0.05[3] 00:29:42 [SUCCESS] db03  16:27:00 up 1 day, 12:32,  1 user,  load average: 0.00, 0.01, 0.05[4] 00:29:42 [SUCCESS] db04  16:27:00 up 1 day, 12:32,  0 users,  load average: 0.01, 0.02, 0.05  pssh通过tar命令解压远程主机文件： pssh -i -h remotehosts "sudo "tar -zxvf /root/pssh-2.3.1.tar.gz -C /root/""pssh -i -h remotehosts "sudo "ls -l /root/""pssh -i -h remotehosts "rm -rf pssh-2.3.1" pssh批量启停远程服务器服务： pssh -i -h remotehosts "sudo "service ntpd restart""pssh -i -h remotehosts "sudo "service ntpd status"" 2）pscp使用案例： pscp -h remotehosts /mnt/pssh-2.3.1.tar.gz /tmp/pscp -h remotehosts -r /mnt/pssh-2.3.1 /tmp/ 3）pslurp使用案例： pslurp -h remotehosts -L /home/hadoop/ /tmp/pssh-2.3.1.tar.gz pssh.tarpslurp -h remotehosts -r -L /home/hadoop/ /tmp/pssh-2.3.1 pssh$lltotal 4drwxrwxr-x 3 hadoop hadoop 34 Oct  5 23:21 db01drwxrwxr-x 3 hadoop hadoop 34 Oct  5 23:21 db02drwxrwxr-x 3 hadoop hadoop 34 Oct  5 23:21 db03drwxrwxr-x 3 hadoop hadoop 34 Oct  5 23:21 db04 4）prsync使用案例： prsync -h remotehosts -l hadoop -a -r /mnt/software/php-5.6.22 /tmp/prsync -h remotehosts -l hadoop -az -r /mnt/software//tmp/ 5）pnuke使用案例： pnuke -h remotehosts "ntpd"
