对于任何人谁碰到这个帖子后失蹄,这里就是我想出了用。请注意,“测试”和“skip_install”是我从脚本调用中分析的标志。
print "Checking for prerequisites (Apache, PHP + PHP development, autoconf, make, gcc)"
prereqs = list("httpd", "php", "php-devel", "autoconf", "make", "gcc")
missing_packages = set()
for package in prereqs:
print "Checking for {0}... ".format([package]),
# Search the RPM database to check if the package is installed
res = yb.rpmdb.searchNevra(name=package)
if res:
for pkg in res:
print pkg, "installed!"
else:
missing_packages.add(package)
print package, "not installed!"
# Install the package if missing
if not skip_install:
if testing:
print "TEST- mock install ", package
else:
try:
yb.install(name=package)
except yum.Errors.InstallError, err:
print >> sys.stderr, "Failed during install of {0} package!".format(package)
print >> sys.stderr, str(err)
sys.exit(1)
# Done processing all package requirements, resolve dependencies and finalize transaction
if len(missing_packages) > 0:
if skip_install:
# Package not installed and set to not install, so fail
print >> sys.stderr, "Please install the {0} packages and try again.".format(
",".join(str(name) for name in missing_packages))
sys.exit(1)
else:
if testing:
print "TEST- mock resolve deps and process transaction"
else:
yb.resolveDeps()
yb.processTransaction()
您是否试过了您链接的网页中的'YumSearch'片段? –
是的,但它的结果似乎没有给我任何安装状态的指示 - 只是rpmdb是否知道软件包(基于指定字段的部分文本匹配)。也许我做错了。 –
