zabbix3.4web界面添加第贰台被监督服务器管理

1. 列表、元组操作

zabbix工具监察和控制服务器是以组的花样来治本,创制单个被监督服务器之前须求先创建3个主机组,然后将被监察和控制机添加到这几个组中即可

列表是大家最以往最常用的数据类型之一,通过列表能够对数据完结最便宜的存款和储蓄、修改等操作

1 创建主机群组:

概念列表

names = [‘Alex’,”Tenglan”,’Eric’]

管理 1

经过下标访问列表中的成分,下标从0开首计数

>>> names[0]
'Alex'
>>> names[2]
'Eric'
>>> names[-1]
'Eric'
>>> names[-2] #还可以倒着取
'Tenglan'

 

管理 2

切开:取多少个因素  

>>> names = ["Alex","Tenglan","Eric","Rain","Tom","Amy"]

>>> names[1:4]  #取下标1至下标4之间的数字,包括1,不包括4

['Tenglan', 'Eric', 'Rain']

>>> names[1:-1] #取下标1至-1的值,不包括-1

['Tenglan', 'Eric', 'Rain', 'Tom']

>>> names[0:3] 

['Alex', 'Tenglan', 'Eric']

>>> names[:3] #如果是从头开始取,0可以忽略,跟上句效果一样

['Alex', 'Tenglan', 'Eric']

>>> names[3:] #如果想取最后一个,必须不能写-1,只能这么写

['Rain', 'Tom', 'Amy'] 

>>> names[3:-1] #这样-1就不会被包含了

['Rain', 'Tom']

>>> names[0::2] #后面的2是代表,每隔一个元素,就取一个

['Alex', 'Eric', 'Tom'] 

>>> names[::2] #和上句效果一样

['Alex', 'Eric', 'Tom']

 

追加

>>> names

['Alex', 'Tenglan', 'Eric', 'Rain', 'Tom', 'Amy']

>>> names.append("我是新来的")

>>> names

['Alex', 'Tenglan', 'Eric', 'Rain', 'Tom', 'Amy', '我是新来的']

管理 3

插入

>>> names

['Alex', 'Tenglan', 'Eric', 'Rain', 'Tom', 'Amy', '我是新来的']

>>> names.insert(2,"强行从Eric前面插入")

>>> names

['Alex', 'Tenglan', '强行从Eric前面插入', 'Eric', 'Rain', 'Tom', 'Amy', '我是新来的']

 

>>> names.insert(5,"从eric后面插入试试新姿势")

>>> names

['Alex', 'Tenglan', '强行从Eric前面插入', 'Eric', 'Rain', '从eric后面插入试试新姿势', 'Tom', 'Amy', '我是新来的']

管理 4

修改

>>> names

['Alex', 'Tenglan', '强行从Eric前面插入', 'Eric', 'Rain', '从eric后面插入试试新姿势', 'Tom', 'Amy', '我是新来的']

>>> names[2] = "该换人了"

>>> names

['Alex', 'Tenglan', '该换人了', 'Eric', 'Rain', '从eric后面插入试试新姿势', 'Tom', 'Amy', '我是新来的']

管理 5

删除

>>> del names[2] 

>>> names

['Alex', 'Tenglan', 'Eric', 'Rain', '从eric后面插入试试新姿势', 'Tom', 'Amy', '我是新来的']

>>> del names[4]

>>> names

['Alex', 'Tenglan', 'Eric', 'Rain', 'Tom', 'Amy', '我是新来的']

>>> 

>>> names.remove("Eric") #删除指定元素

>>> names

['Alex', 'Tenglan', 'Rain', 'Tom', 'Amy', '我是新来的']

>>> names.pop() #删除列表最后一个值 

'我是新来的'

>>> names

['Alex', 'Tenglan', 'Rain', 'Tom', 'Amy']

2 向长机群组中添加主机

扩展

>>> names

['Alex', 'Tenglan', 'Rain', 'Tom', 'Amy']

>>> b = [1,2,3]

>>> names.extend(b)

>>> names

['Alex', 'Tenglan', 'Rain', 'Tom', 'Amy', 1, 2, 3]

管理 6

拷贝

>>> names

['Alex', 'Tenglan', 'Rain', 'Tom', 'Amy', 1, 2, 3]

 

>>> name_copy = names.copy()

>>> name_copy

['Alex', 'Tenglan', 'Rain', 'Tom', 'Amy', 1, 2, 3]

 

管理 7

统计

>>> names

['Alex', 'Tenglan', 'Amy', 'Tom', 'Amy', 1, 2, 3]

>>> names.count("Amy")

2

管理 8

排序&翻转

>>> names

['Alex', 'Tenglan', 'Amy', 'Tom', 'Amy', 1, 2, 3]

>>> names.sort() #排序

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

TypeError: unorderable types: int() < str()   #3.0里不同数据类型不能放在一起排序了,擦

>>> names[-3] = '1'

>>> names[-2] = '2'

>>> names[-1] = '3'

>>> names

['Alex', 'Amy', 'Amy', 'Tenglan', 'Tom', '1', '2', '3']

>>> names.sort()

>>> names

['1', '2', '3', 'Alex', 'Amy', 'Amy', 'Tenglan', 'Tom']

 

>>> names.reverse() #反转

>>> names

['Tom', 'Tenglan', 'Amy', 'Amy', 'Alex', '3', '2', '1']

 

 

获取下标

>>> names

['Tom', 'Tenglan', 'Amy', 'Amy', 'Alex', '3', '2', '1']

>>> names.index("Amy")

2 #只返回找到的第一个下标

3
向长机中添加模板,选择要监督哪些服务等

元组

元组其实跟列表大约,也是存一组数,只不是它如若创设,便不能够再修改,所以又叫只读列表

语法

names = ("alex","jack","eric")

管理 9

2. 字符串操作   

特点:不可修改 

 

name.capitalize()  首字母大写

name.casefold()   大写全体变小写

name.center(50,”-“)  输出 ‘———————Alex
Li———————-‘

name.count(‘lex’) 总结 lex出现次数

name.encode()  将字符串编码成bytes格式

name.endswith(“Li”)  判断字符串是不是以 Li结尾

 “Alex\tLi”.expandtabs(10) 输出’Alex      Li’, 将\t转换到多少长度的空格

 name.find(‘A’)  查找A,找到重回其索引, 找不到重临-1

 

format :

    >>> msg = "my name is {}, and age is {}"

    >>> msg.format("alex",22)

    'my name is alex, and age is 22'

    >>> msg = "my name is {1}, and age is {0}"

    >>> msg.format("alex",22)

    'my name is 22, and age is alex'

    >>> msg = "my name is {name}, and age is {age}"

    >>> msg.format(age=22,name="ale")

    'my name is ale, and age is 22'

format_map

    >>> msg.format_map({'name':'alex','age':22})

    'my name is alex, and age is 22'

 

 

msg.index(‘a’)  返回a所在字符串的目录

‘9aA’.isalnum()   True

 

‘9’.isdigit() 是或不是整数

name.isnumeric 

name.isprintable

name.isspace

name.istitle

name.isupper

 “|”.join([‘alex’,’jack’,’rain’])

‘alex|jack|rain’

 

 

maketrans

    >>> intab = "aeiou"  #This is the string having actual characters. 

    >>> outtab = "12345" #This is the string having corresponding mapping character

    >>> trantab = str.maketrans(intab, outtab)

    >>> 

    >>> str = "this is string example....wow!!!"

    >>> str.translate(trantab)

    'th3s 3s str3ng 2x1mpl2....w4w!!!'

 

 msg.partition('is')   输出 ('my name ', 'is', ' {name}, and age is {age}') 

 

 >>> "alex li, chinese name is lijie".replace("li","LI",1)

     'alex LI, chinese name is lijie'

 

 msg.swapcase 大小写互换

 

 

 >>> msg.zfill(40)

'00000my name is {name}, and age is {age}'

 

 

 

>>> n4.ljust(40,"-")

'Hello 2orld-----------------------------'

>>> n4.rjust(40,"-")

'-----------------------------Hello 2orld'

 

 

>>> b="ddefdsdff_哈哈" 

>>> b.isidentifier() #检测一段字符串可否被当作标志符,即是否符合变量命名规则

True

3. 字典操作

字典一种key – value
的数据类型,使用就如大家上学用的字典,通过笔划、字母来核查应页的详尽内容。

语法:

info = {

    'stu1101': "TengLan Wu",

    'stu1102': "LongZe Luola",

    'stu1103': "XiaoZe Maliya",

}

管理 11

字典的特色:

  • dict是无序的
  • key必须是绝无仅有的,so 天生去重
    • 增加

 

>>> info["stu1104"] = "苍井空"

>>> info

{'stu1102': 'LongZe Luola', 'stu1104': '苍井空', 'stu1103': 'XiaoZe Maliya', 'stu1101': 'TengLan Wu'}

管理 12

修改

 

>>> info['stu1101'] = "武藤兰"

>>> info

{'stu1102': 'LongZe Luola', 'stu1103': 'XiaoZe Maliya', 'stu1101': '武藤兰'}

管理 13

删除

>>> info

{'stu1102': 'LongZe Luola', 'stu1103': 'XiaoZe Maliya', 'stu1101': '武藤兰'}

>>> info.pop("stu1101") #标准删除姿势

'武藤兰'

>>> info

{'stu1102': 'LongZe Luola', 'stu1103': 'XiaoZe Maliya'}

>>> del info['stu1103'] #换个姿势删除

>>> info

{'stu1102': 'LongZe Luola'}

>>> 

>>> 

>>> 

>>> info = {'stu1102': 'LongZe Luola', 'stu1103': 'XiaoZe Maliya'}

>>> info

{'stu1102': 'LongZe Luola', 'stu1103': 'XiaoZe Maliya'} #随机删除

>>> info.popitem()

('stu1102', 'LongZe Luola')

>>> info

{'stu1103': 'XiaoZe Maliya'}

 

查找

>>> info = {'stu1102': 'LongZe Luola', 'stu1103': 'XiaoZe Maliya'}

>>> 

>>> "stu1102" in info #标准用法

True

>>> info.get("stu1102")  #获取

'LongZe Luola'

>>> info["stu1102"] #同上,但是看下面

'LongZe Luola'

>>> info["stu1105"]  #如果一个key不存在,就报错,get不会,不存在只返回None

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

KeyError: 'stu1105'

4.集合操作

聚拢是一个无序的,不另行的多少整合,它的严重性效率如下:

  • 去重,把二个列表变成集合,就自动去重了
  • 事关测试,测试两组数据此前的长短不一、差集、并集等涉及

管理 17

常用操作

 

s = set([3,5,9,10])      #创建一个数值集合  

  

t = set("Hello")         #创建一个唯一字符的集合  

 

a = t | s          # t 和 s的并集  

  

b = t & s          # t 和 s的交集  

  

c = t – s          # 求差集(项在t中,但不在s中)  

  

d = t ^ s          # 对称差集(项在t或s中,但不会同时出现在二者中)  

  

 

基本操作: 

  

t.add('x')            # 添加一项  

  

s.update([10,37,42])  # 在s中添加多项  

  

   

  

使用remove()可以删除一项:  

  

t.remove('H')  

  

  

len(s)  

set 的长度  

  

x in s  

测试 x 是否是 s 的成员  

  

x not in s  

测试 x 是否不是 s 的成员  

  

s.issubset(t)  

s <= t  

测试是否 s 中的每一个元素都在 t 中  

  

s.issuperset(t)  

s >= t  

测试是否 t 中的每一个元素都在 s 中  

  

s.union(t)  

s | t  

返回一个新的 set 包含 s 和 t 中的每一个元素  

  

s.intersection(t)  

s & t  

返回一个新的 set 包含 s 和 t 中的公共元素  

  

s.difference(t)  

s - t  

返回一个新的 set 包含 s 中有但是 t 中没有的元素  

  

s.symmetric_difference(t)  

s ^ t  

返回一个新的 set 包含 s 和 t 中不重复的元素  

  

s.copy()  

返回 set “s”的一个浅复制  

5.文本操作

对文本操作流程

  1. 开辟文件,获得文件句柄并赋值给四个变量
  2. 经过句柄对文本进行操作
  3. 关闭文件

基本操作  

f = open(‘lyrics’) #打开文件

first_line = f.readline()

print(‘first line:’,first_line) #读一行

print(‘作者是分隔线’.center(50,’-‘))

data = f.read()# 读取剩下的保有情节,文件大时不要用

print(data) #打字与印刷文件

 

f.close() #闭馆文件

开拓文件的方式有:

  • r,只读情势(默许)。
  • w,只写情势。【不可读;不设有则创设;存在则删除内容;】
  • a,追加格局。【可读;   不存在则开创;存在则只扩张内容;】

“+” 表示能够而且读写有个别文件

  • r+,可读写文件。【可读;可写;可增添】
  • w+,写读
  • a+,同a

“U”表示在读取时,可以将 \r \n \r\n自动转换来 \n (与 r 或 r+
情势同使用)

  • rU
  • r+U

“b”表示处理二进制文件(如:FTP发送上传ISO镜像文件,linux可忽略,windows处理二进制文件时需标注)

  • rb
  • wb
  • ab

其他语法

 

    def close(self): # real signature unknown; restored from
__doc__

        “””

        Close the file.

       

        A closed file cannot be used for further I/O operations. 
close() may be

        called more than once without error.

        “””

        pass

 

    def fileno(self, *args, **kwargs): # real signature unknown

        “”” Return the underlying file descriptor (an integer). “””

        pass

 

    def isatty(self, *args, **kwargs): # real signature unknown

        “”” True if the file is connected to a TTY device. “””

        pass

 

    def read(self, size=-1): # known case of _io.FileIO.read

        “””

        注意,不自然能全读回来

        Read at most size bytes, returned as bytes.

       

        Only makes one system call, so less data may be returned than
requested.

        In non-blocking mode, returns None if no data is available.

        Return an empty bytes object at EOF.

        “””

        return “”

 

    def readable(self, *args, **kwargs): # real signature unknown

        “”” True if file was opened in a read mode. “””

        pass

 

    def readall(self, *args, **kwargs): # real signature unknown

        “””

        Read all data from the file, returned as bytes.

       

        In non-blocking mode, returns as much as is immediately
available,

        or None if no data is available.  Return an empty bytes object
at EOF.

        “””

        pass

 

    def readinto(self): # real signature unknown; restored from
__doc__

        “”” Same as RawIOBase.readinto(). “””

        pass #毫不用,没人知道它是干嘛用的

 

    def seek(self, *args, **kwargs): # real signature unknown

        “””

        Move to new file position and return the file position.

       

        Argument offset is a byte count.  Optional argument whence
defaults to

        SEEK_SET or 0 (offset from start of file, offset should be
>= 0); other values

        are SEEK_CUR or 1 (move relative to current position, positive
or negative),

        and SEEK_END or 2 (move relative to end of file, usually
negative, although

        many platforms allow seeking beyond the end of a file).

       

        Note that not all file objects are seekable.

        “””

        pass

 

    def seekable(self, *args, **kwargs): # real signature unknown

        “”” True if file supports random-access. “””

        pass

 

    def tell(self, *args, **kwargs): # real signature unknown

        “””

        Current file position.

       

        Can raise OSError for non seekable files.

        “””

        pass

 

    def truncate(self, *args, **kwargs): # real signature unknown

        “””

        Truncate the file to at most size bytes and return the truncated
size.

       

        Size defaults to the current file position, as returned by
tell().

        The current file position is changed to the value of size.

        “””

        pass

 

    def writable(self, *args, **kwargs): # real signature unknown

        “”” True if file was opened in a write mode. “””

        pass

 

    def write(self, *args, **kwargs): # real signature unknown

        “””

        Write bytes b to file, return number written.

       

        Only makes one system call, so not all of the data may be
written.

        The number of bytes actually written is returned.  In
non-blocking mode,

        returns None if the write would block.

        “””

        pass

with语句

为了防止打开文件后忘记关闭,能够透过管住上下文,即:

with open(‘log’,’r’) as f:

     

    …

这般方法,当with代码块执行完成时,内部会活动关闭并释放文件能源。

在Python 2.7 后,with又帮忙同时对几个文件的上下文实行保管,即:

with open(‘log1’) as obj1, open(‘log2’) as obj2:

    pass

6. 字符编码与转码

 

需知:

1.在python2默许编码是ASCII, python3里暗许是unicode

2.unicode 分为
utf-32(占四个字节),utf-16(占多少个字节),utf-8(占1-五个字节), so
utf-16正是后天最常用的unicode版本,
可是在文件里存的照旧utf-8,因为utf8省上空

3.在py3中encode,在转码的还要还会把string
变成bytes类型,decode在解码的同时还会把bytes变回string

 管理 18

 

上海图书馆仅适用于py2
