使用wget命令时发生错误
用的是centos6.5, 当我使用命今
sudo wget https://cmake.org/files/v3.6/cmake-3.6.1.tar.gz
下载个cmake的包时, 发生了这样的错误
--2016-09-01 06:53:39-- https://cmake.org/files/v3.6/cmake-3.6.1.tar.gzResolving cmake.org... 66.194.253.19Connecting to cmake.org|66.194.253.19|:443... connected.ERROR: certificate common name “*.kitware.com” doesn’t match requested host name “cmake.org”.To connect to cmake.org insecurely, use ‘--no-check-certificate’.
没有检验证书, 应该是这样的意思吧. 可能是我这服务器的证书问题吧..
现在查看一下wget的帮助(wget option URL):
GNU Wget 1.12, a non-interactive network retriever.Usage: wget [OPTION]... [URL]...Mandatory arguments to long options are mandatory for short options too.Startup: -V, --version display the version of Wget and exit. -h, --help print this help. -b, --background go to background after startup. -e, --execute=COMMAND execute a ‘.wgetrc’-style command.Logging and input file: -o, --output-file=FILE log messages to FILE. -a, --append-output=FILE append messages to FILE. -d, --debug print lots of debugging information. -q, --quiet quiet (no output). -v, --verbose be verbose (this is the default). -nv, --no-verbose turn off verboseness, without being quiet. -i, --input-file=FILE download URLs found in local or external FILE. -F, --force-html treat input file as HTML. -B, --base=URL resolves HTML input-file links (-i -F) relative to URL.Download: -t, --tries=NUMBER set number of retries to NUMBER (0 unlimits). --retry-connrefused retry even if connection is refused. -O, --output-document=FILE write documents to FILE. -nc, --no-clobber skip downloads that would download to existing files. -c, --continue resume getting a partially-downloaded file. --progress=TYPE select progress gauge type. -N, --timestamping don’t re-retrieve files unless newer than local. -S, --server-response print server response. --spider don’t download anything. -T, --timeout=SECONDS set all timeout values to SECONDS. --dns-timeout=SECS set the DNS lookup timeout to SECS. --connect-timeout=SECS set the connect timeout to SECS. --read-timeout=SECS set the read timeout to SECS. -w, --wait=SECONDS wait SECONDS between retrievals. --waitretry=SECONDS wait 1..SECONDS between retries of a retrieval. --random-wait wait from 0...2*WAIT secs between retrievals. --no-proxy explicitly turn off proxy. -Q, --quota=NUMBER set retrieval quota to NUMBER. --bind-address=ADDRESS bind to ADDRESS (hostname or IP) on local host. --limit-rate=RATE limit download rate to RATE. --no-dns-cache disable caching DNS lookups. --restrict-file-names=OS restrict chars in file names to ones OS allows. --ignore-case ignore case when matching files/directories. -4, --inet4-only connect only to IPv4 addresses. -6, --inet6-only connect only to IPv6 addresses. --prefer-family=FAMILY connect first to addresses of specified family, one of IPv6, IPv4, or none. --user=USER set both ftp and http user to USER. --password=PASS set both ftp and http password to PASS. --ask-password prompt for passwords. --no-iri turn off IRI support. --local-encoding=ENC use ENC as the local encoding for IRIs. --remote-encoding=ENC use ENC as the default remote encoding.Directories: -nd, --no-directories don’t create directories. -x, --force-directories force creation of directories. -nH, --no-host-directories don’t create host directories. --protocol-directories use protocol name in directories. -P, --directory-prefix=PREFIX save files to PREFIX/... --cut-dirs=NUMBER ignore NUMBER remote directory components.HTTP options: --http-user=USER set http user to USER. --http-password=PASS set http password to PASS. --no-cache disallow server-cached data. --default-page=NAME Change the default page name (normally this is ‘index.html’.). -E, --adjust-extension save HTML/CSS documents with proper extensions. --ignore-length ignore ‘Content-Length’ header field. --header=STRING insert STRING among the headers. --max-redirect maximum redirections allowed per page. --proxy-user=USER set USER as proxy username. --proxy-password=PASS set PASS as proxy password. --referer=URL include ‘Referer: URL’ header in HTTP request. --save-headers save the HTTP headers to file. -U, --user-agent=AGENT identify as AGENT instead of Wget/VERSION. --no-http-keep-alive disable HTTP keep-alive (persistent connections). --no-cookies don’t use cookies. --load-cookies=FILE load cookies from FILE before session. --save-cookies=FILE save cookies to FILE after session. --keep-session-cookies load and save session (non-permanent) cookies. --post-data=http://www.mamicode.com/STRING use the POST method; send STRING as the data.>
然后我就可以用
sudo wget --no-check-certificate https://cmake.org/files/v3.6/cmake-3.6.1.tar.gz
然后就ok了...很简单的一个操作
