03-04_配置并启动Managed Server(受管服务器)

时间：2023-11-11 12:38:44

本文重点：

  1. 配置Managed Servers（受管服务器）
  2. 启动Managed Servers
  3. 原理
  4. 运行多个Managed Servers实例

 
 

 
 

 
 

一、配置Managed Servers

  1. 配置Managed Server可以通过以下方式：
    1. Domains配置助手（本文略）
    2. Web控制台
    3. WLST配置脚本（后续脚本管理时会创建）

     
     

  2. 通过web控制台配置Managed Servers
    1. 登录web控制台：

      03-04_配置并启动Managed Server(受管服务器)

    2. 创建服务器：

      03-04_配置并启动Managed Server(受管服务器)

       
       

      由于默认Admin Server占用了7001，所以需要使用其他端口

      03-04_配置并启动Managed Server(受管服务器)

    3. 创建成功

      03-04_配置并启动Managed Server(受管服务器)

  3. 通过WLST脚本配置Managed Server

    暂略，后续更新超链接。

 
 

二、启动Managed Server

  1. 启动Server-0（Managed Server）

    该例子是和AdminServer在同一台服务器上启动，所以省事，如果在其他服务器启动，是需要将weblogic安装介质（/opt/weblogic）和weblogic Domains文件给复制过去的。（/opt/wldomains/base_domains）

[root@wls1 ~]# /opt/wldomains/base_domains/bin/startManagedWebLogic.sh Server-0 http://127.0.0.1:7001

  1. 启动成功
  2. 03-04_配置并启动Managed Server(受管服务器)
  3. 创建一个Server-0修改了哪些东西？

[root@wls1 ~]# cat /opt/wldomains/base_domains/config/config.xml

<server>

<name>AdminServer</name>

<listen-address></listen-address>

</server>

<server>

<name>Server-0</name>

<listen-port>10001</listen-port>

<web-server>

<web-server-log>

<number-of-files-limited>false</number-of-files-limited>

</web-server-log>

</web-server>

<listen-address></listen-address>

</server>
  1. 启动一个Server-0生成了哪些东西？

[root@wls1 ~]# ls -lha /opt/wldomains/base_domains/servers/Server-0/

total 0

drwxr----- 6 root root 54 Jan 18 23:03 .

drwxr-x--- 7 root root 91 Jan 18 23:03 ..

drwxr----- 3 root root 25 Jan 18 23:03 cache

drwxr----- 4 root root 31 Jan 18 23:03 data

drwxr----- 3 root root 69 Jan 18 23:03 logs

drwxr----- 4 root root 70 Jan 18 23:04 tmp
  1. 连接Admin Server的时候避免输入密码：

[root@wls1 ~]# mkdir -pv /opt/wldomains/base_domains/servers/Server-0/security

mkdir: created directory '/opt/wldomains/base_domains/servers/Server-0/security'

[root@wls1 ~]# cat /opt/wldomains/base_domains/servers/Server-0/security/boot.properties

username=weblogic

password=!QAZ2wsx

 
 

第一次连接后会对该文件帐号密码进行加密，如下所示：

[root@wls1 cache]# cat /opt/wldomains/base_domains/servers/Server-0/security/boot.properties

  • 关闭Managed Server
    • 方式 1：直接Curt + C终止或kill干掉进程
    • 方式 2：Web控制台关闭

      03-04_配置并启动Managed Server(受管服务器)

 
 

三、原理

  1. Managed Server启动数据流

    03-04_配置并启动Managed Server(受管服务器)

     
     

    03-04_配置并启动Managed Server(受管服务器)

     
     

    步骤1：先在Admin Server（192.168.1.1）新建ServerA和ServerB，并将ServerA和ServerB加入到集群中，同时会将更改写进config/config.xml配置文件中，会将日志写进log文件中。

    步骤2：服务器A（192.168.1.2）或服务器B（192.168.1.3）启动Server的时候，先进行认证（Admin Server的帐号密码），然后自动下载Admin Server的配置，加载到内存中后按照配置启动运行。

     
     

    注意1：上图中ServerA、ServerB和Proxy可以在任意服务器上启动并运行，但只能同一时间运行在同一服务器上。具体请看另一篇《03-01_WebLogic一些概念名词》的Server章节。

    注意2：所有的更改都是在Admin Server上更改的。

  • 手工启动Managed Server，必须要有：
    • 必须指定Server名字，这个server名字必须在Admin Server配置OK，例如上述示例中的Server-0。
    • 必须指定Admin Server（管理服务器）的URL，例如上述示例中的http://127.0.0.1:7001。

      03-04_配置并启动Managed Server(受管服务器)

  • 启动标识文件（密码文件）
    • 作用：不用重复输入密码，开发模式下Admin Server会自动创建自己的密码文件，而生产模式则不会，受管服务器都要手工创建密码文件。
    • 文件路径：$DOMAINS/servers/SERVER_NAME/security，例如上述示例的/opt/wldomains/base_domains/servers/Server-0/security/boot.properties
    • 示例：

      03-04_配置并启动Managed Server(受管服务器)

    • 注意1：如果帐号密码有问题，相当于该文件无效，依然会提示输入。
    • 注意2：该文件复制到其他的Server无效，ServerA只能适用ServerA，ServerB只能适用ServerB
  1. Managed Server（受管服务器根路径）

$DOMAINS/servers/SERVER_NAME/

比如上述示例：/opt/wldomains/base_domains/servers/Server-0/
  1. 更改boot.properties默认路径

可以在java参数添加一行：-Dweblogic.system.BootldentityFile=filename
  1. 不使用boot.properties，要么手工输入帐号密码，要么参数输入帐号密码，参数如下

-Dweblogic.management.username=username

-Dweblogic.management.password=password

 
 

四、运行多个Managed Server实例

  1. 先通过web控制台新建一个服务器Server-1，端口设置为10002
  2. 使用/opt/wldomains/base_domains/bin/startManagedWebLogic.sh Server-1 http://127.0.0.1:7001
  3. 输入帐号密码，就启动成功了。
  4. 运行2个与运行多个什么区别。
