我对电子产品向来没什么抵抗力. 今天败了htc p4550和sony prs 505. 等货到手这段时间是最心焦的. p4550还好, 是天津过来的. 505得从美国过来. 估计得个10天半月

我等 我等

安装步骤基本和Ubuntu下差不多, 只不过需要多装一个pam_userdb, 我是yum装的 yum install db4-utils

ubuntu下参考之前的文章: http://blog.bigcomic.com/post/241.html

有一点不同的是ubuntu下的pam日志在 /var/log/auth.log.  而centos5.2是在 /var/log/secure

NRPE

NRPE is an addon that allows you to execute plugins on remote Linux/Unix hosts. This is useful if you need to monitor local resources/attributes like disk usage, CPU load, memory usage, etc. on a remote host. Similiar functionality can be accomplished by using the check_by_ssh plugin, although it can impose a higher CPU load on the monitoring machine - especially if you are monitoring hundreds or thousands of hosts.

NSCA

NSCA is an addon that allows you to send passive check results from remote Linux/Unix hosts to the Nagios daemon running on the monitoring server. This is very useful in distributed and redundant/failover monitoring setups.

NSClient++

Monitoring private services or attributes of a Windows machine requires that you install an agent on it. This agent acts as a proxy between the Nagios plugin that does the monitoring and the actual service or attribute of the Windows machine. Without installing an agent on the Windows box, Nagios would be unable to monitor private services or attributes of the Windows box.

NDOUtils

NDOUtils is an addon that allows you to store all status information from Nagios in a MySQL database. Multiple instances of Nagios can all store their information in a central database for centralized reporting. This will likely serve as the basis for a new PHP-based web interface for Nagios in the future.

返回结果数量限制:
Entry.objects.all()[:5]   LIMIT 5
Entry.objects.all()[5:10]  OFFSET 5 LIMIT 5
Entry.objects.all()[:10:2]  step 2
Entry.objects.order_by('headline')[0] LIMIT 1

数据操作:
.delete()    删除
.save()     更新
.count()    结果数量

容错处理:

from django.core.exceptions import ObjectDoesNotExist
try:
 e = Entry.objects.get(id=3)
except ObjectDoesNotExist:
 print "Either the entry doesn't exist."

try:
    obj = Person.objects.get(first_name='John', last_name='Lennon')
except Person.DoesNotExist:
    obj = Person(first_name='John', last_name='Lennon', birthday=date(1940, 10, 9))

可以使用绿毛龟（svn客户端）来查看项目情况，使用svn://ip:port/test来查看项目源码

配置
#cd /home/svndata/test/conf
#vi authz
 [groups]对组进行配置
 # harry_and_sally = harry,sally

 # [/foo/bar]按目录进行用户读写配置
 # harry = rw
 # * =

 [repository:/test]对svn库的路径进行配置
 # @harry_and_sally = rw
 # * = r
 radio=rw
 pencat=rw
 koala=rw
 soul=rw
#vi passwd
 [users]
 # harry = harryssecret
 # sally = sallyssecret
 radio=123456
 都是明文的
#vi svnserv.conf
password-db = passwd将这行的注释去掉，就会要求用户验证

svn换端口
#./svnserve --help 可以看到命令，里面有个参数--listen-port
不过我没有使用过

因为ssl关系出现认证失败的解决办法
1、停掉ssl
2、# authz-db = authz这行的#保留

#去掉#[general]前面的#号
[general]
#匿名访问的权限，可以是read,write,none,默认为read
anon-access = none
#认证用户的权限，可以是read,write,none,默认为write
auth-access = write
#密码数据库的路径，去掉前面的#
password-db = passwd
