Kukonza Scripts Property

Katundu wa Scripts amakuthandizani kuti musinthe mawonekedwe anu a CSR1000v. Ngati mukufuna kuyendetsa Python kapena Bash script pa Day0 pansi pa alendo, perekani anthu URL ndi mikangano ya python kapena bash script mu Scripts katundu. Zolemba ziyenera kukhala ndi kachidutswa ka code komwe kumaphatikizapo zilembo za shebang (!) pamzere woyamba wa script. Mzerewu umauza Cisco IOS-XE kuti ndi womasulira wotani (Python kapena Bash) yemwe muyenera kugwiritsa ntchito kusanthula kachidindo. Za example, mzere woyamba wa Python script ukhoza kukhala ndi #!/usr/bin/env python, pomwe mzere woyamba wa Bash script utha kukhala ndi #!/bin/bash. Mzerewu umalola kuti Python kapena Bash script igwire ntchito ngati code yotheka ku Linux. Mukamaliza kulemba, script imayenda mu chidebe cha alendo cha Cisco CSR 1000v. Kuti mupeze chidebe cha alendo, gwiritsani ntchito lamulo la EXEC la alendo. Kuti mumve zambiri pazalamulo la guesthell, onani Programmability Configuration Guide. Kuti mukonze malo a Scripts, gwiritsani ntchito mawonekedwe awa:
Gawo: scripts
anthu_url
Mu script iyi, mzere woyamba wa malowo uyenera kuwerenga Gawo: Zolemba. Mu mzere wachiwiri wa katunduyo, lowetsani URL za script ndi zotsutsana za script. Zolembazo zitha kukhala Python kapena Bash script. Zolemba zimayendetsedwa mu guesthell mu boot yoyamba pamene mukweza deta yanu file, mukapanga chitsanzo cha CSR1000v. Ku view zambiri exampzolemba, onani "scripts" pa: https://github.com/csr1000v/customdata-examples. Komanso, onetsani ex zotsatiraziampzochepa:

Zindikirani Ngati script mu katundu wa Scripts ikufuna phukusi la Python lomwe silinaphatikizidwe mu kutulutsidwa kwa CentOS Linux (kutulutsidwa kwa CentOS Linux komwe kukugwiritsidwa ntchito ndi alendo ndi CentOS Linux kumasulidwa 7.1.1503), muyenera kuphatikizapo zambiri za phukusi la Python. mu Python package katundu. Kuti mumve zambiri, onani: Kukonzekera Katundu wa Python, Musanafikire zomwe mwazolowera ndikuyendetsa Bash kapena Python script, Cisco ikukulimbikitsani kuti muyese
URL zomwe mukufuna kugwiritsa ntchito, pogwiritsa ntchito Scripts katundu. Mutha kuyesa ftp://10.11.0.4/dir1/dir2/script.py -a arg1 -s arg2 poyendetsa curl chida cha pulogalamu kutsitsa script file. M'nyumba ya alendo, lowetsani curl lamula monga momwe tawonetsera mu exampndi: curl -m 30 -yesanso 5 -lolowera: password ftp://10.11.0.4/dir1/dir2/script_needs_credentials.py. Ngati curl lamulo likuyenda bwino, kopi ya Python script imatsitsidwa, yomwe imatsimikizira ngati URL ndi zolondola.

Kukonza Script Credentials Property

Ngati mwatchula seva ya FTP muzolemba za Script, ndipo seva ikufuna dzina lolowera ndi mawu achinsinsi, tchulani zidziwitso pogwiritsa ntchito chizindikiro cha Script.

Zindikirani Ngati mutha kulowa pa seva ya FTP mosadziwika, simuyenera kugwiritsa ntchito chizindikiro cha Script. Konzani katundu wa Scripts ndi a URL ndi magawo omwe akufanana ndi omwe ali mu script credentials katundu. Kuti mukonze zotsimikizira za Script, gwiritsani ntchito mtundu wotsatirawu: Gawo: Script credentials public_url
Example
Gawo: Zikalata zotsimikizira
ftp://10.11.0.4/dir1/dir2/script1.py userfoo foospass Mzere wachiwiri mu script credentials katundu umatchula zamtengo wapatali wa dzina lolowera (userfoo) ndi mbiri yachinsinsi (foospass) ya python script1.py. Phatikizani dzina la seva ya FTP yomwe ilinso mu Scripts katundu. Example mzere mu katundu wa Scripts ndi: ftp://10.11.0.4/dir1/dir2/script1.py -a arg1 -s arg2. Onani chitsanzoample 2 mu Kukonza Katundu wa Zolemba,

Kukonza katundu wa Python package

Ngati phukusi la Python likufunika ndi script mu katundu wa Scripts ndipo siliri gawo la CentOS Linux yotulutsidwa 7.1.1503, muyenera kuphatikizapo zambiri za phukusi mu katundu wa Python phukusi. Mwa kuphatikiza katundu wa phukusi la Python mu bootstrap file, mumaonetsetsa kuti Cisco CSR 1000v imatsitsidwa ndikuyika phukusi lofunikira la Python musanayambe chizolowezi. file zomwe mudazitchula mu Scripts katundu.
Konzani Python Package Property
Kuti mukonze katundu wa phukusi la Python, gwiritsani ntchito mawonekedwe awa:
Gawo: Phukusi la Python
