通过python脚本来修改apache的配置文件：
该脚本可以解析apache配置文件，找到VirtualHost部分，替换DocumentRoot。
#!/usr/bin/python
from cStringIO import StringIO
import re
vhost_start = re.compile(r'<VirtualHost\s+(.*?)>')
vhost_end = re.compile(r'</VirtualHost>')
docroot_re = re.compile(r'(DocumentRoot\s+)(\S+)')
def replace_docroot(conf_string, vhost, new_docroot):
'''yield new lines of an httpd.conf file where docroot lines matching
the specified vhost are replaced with the new_docroot
'''
conf_file = StringIO(conf_string)
in_vhost = False
curr_vhost = None
for line in conf_file:
vhost_start_match = vhost_start.search(line)
if vhost_start_match:
curr_vhost = vhost_start_match.groups()[0]
in_vhost = True
if in_vhost and (curr_vhost == vhost):
docroot_match = docroot_re.search(line)
if docroot_match:
sub_line = docroot_re.sub(r'\1%s' % new_docroot, line)
line = sub_line
vhost_end_match = vhost_end.search(line)
if vhost_end_match:
in_vhost = False
yield line
if __name__ == '__main__':
import sys
conf_file = sys.argv[1]
vhost = sys.argv[2]
docroot = sys.argv[3]
conf_string = open(conf_file).read()
for line in replace_docroot(conf_string, vhost, docroot):
print line,
