weblogic安装 12.2.1.4.0集群

article 2025/3/1 12:03:18

两台服务器都需要安装JDK和WebLogic
在两台服务器上都执行以下步骤：

# 安装JDK
# 1. 创建Java安装目录
mkdir -p /usr/java
cd /usr/java

# 2. 解压JDK
tar -zxvf /path/to/jdk-8u341-linux-x64.tar.gz

# 3. 配置环境变量
cat >> /etc/profile << 'EOF'
export JAVA_HOME=/usr/java/jdk1.8.0_341
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
EOF

# 4. 使环境变量生效
source /etc/profile

# 5. 验证JDK安装
java -version

服务器1配置（AdminServer + Managed Server1）

# 1. 创建域配置脚本
cat > /home/weblogic/create_domain.py << EOF
readTemplate('/home/weblogic/oracle/middleware/wlserver/common/templates/wls/wls.jar')

# 配置AdminServer
cd('Servers/AdminServer')
set('ListenAddress','192.168.1.101')
set('ListenPort', 7001)

# 创建Machine1
cd('/')
create('Machine1', 'Machine')
cd('Machine/Machine1')
create('Machine1', 'NodeManager')
cd('NodeManager/Machine1')
set('ListenAddress', '192.168.1.101')
set('ListenPort', 5556)

# 创建Machine2
cd('/')
create('Machine2', 'Machine')
cd('Machine/Machine2')
create('Machine2', 'NodeManager')
cd('NodeManager/Machine2')
set('ListenAddress', '192.168.1.102')
set('ListenPort', 5556)

# 创建Server1
cd('/')
create('Server1', 'Server')
cd('Server/Server1')
set('ListenAddress', '192.168.1.101')
set('ListenPort', 7003)
set('Machine', 'Machine1')

# 创建Server2
cd('/')
create('Server2', 'Server')
cd('Server/Server2')
set('ListenAddress', '192.168.1.102')
set('ListenPort', 7003)
set('Machine', 'Machine2')

# 设置管理员密码
cd('/')
cd('Security/base_domain/User/weblogic')
cmo.setPassword('weblogic2022')

# 创建域
setOption('OverwriteDomain', 'true')
writeDomain('/home/weblogic/oracle/middleware/user_projects/domains/base_domain')
closeTemplate()
exit()
EOF

# 2. 执行域创建
cd /home/weblogic/oracle/middleware/oracle_common/common/bin
./wlst.sh /home/weblogic/create_domain.py

配置Node Manager（两台服务器都需要）

# 1. 创建Node Manager配置
cd /home/weblogic/oracle/middleware/user_projects/domains/base_domain/nodemanager
cat > nodemanager.properties << EOF
ListenAddress=
ListenPort=5556
SecureListener=false
WebLogicHome=/home/weblogic/oracle/middleware/wlserver
DomainsFile=/home/weblogic/oracle/middleware/wlserver/common/nodemanager/nodemanager.domains
LogLimit=0
LogLevel=INFO
LogToStderr=true
LogCount=1
DomainsDirRemoteSharingEnabled=true
StartScriptEnabled=true
NativeVersionEnabled=true
EOF

服务器2配置

# 1. 复制域配置
# 在服务器1上打包域配置
cd /home/weblogic/oracle/middleware/user_projects/domains
tar czf base_domain.tar.gz base_domain

# 将base_domain.tar.gz传输到服务器2并解压
scp base_domain.tar.gz weblogic@192.168.1.102:/home/weblogic/oracle/middleware/user_projects/domains/
cd /home/weblogic/oracle/middleware/user_projects/domains
tar xzf base_domain.tar.gz

启动顺序
在服务器1上：

# 1. 启动Node Manager
cd /home/weblogic/oracle/middleware/user_projects/domains/base_domain/bin
./startNodeManager.sh

# 2. 启动AdminServer
./startWebLogic.sh

# 3. 启动Managed Server1
./startManagedWebLogic.sh Server1

在服务器2上：

# 1. 启动Node Manager
cd /home/weblogic/oracle/middleware/user_projects/domains/base_domain/bin
./startNodeManager.sh

# 2. 启动Managed Server2
./startManagedWebLogic.sh Server2 http://192.168.1.101:7001

验证配置
访问WebLogic控制台：

http://192.168.1.101:7001/console
用户名：weblogic
密码：weblogic2022

以上完成两台weblogic主备配置

检查：

Node Manager状态
Managed Servers状态
集群通信
4.在WebLogic集群环境中，config.xml是关键配置文件。虽然通过create_domain.py脚本创建域时会自动生成基本配置，但我们可以检查和修改config.xml以确保配置正确：
config.xml位置：/home/weblogic/oracle/middleware/user_projects/domains/base_domain/config/config.xml

需要检查的关键配置：

<?xml version='1.0' encoding='UTF-8'?>
<domain xmlns="http://xmlns.oracle.com/weblogic/domain" xmlns:sec="http://xmlns.oracle.com/weblogic/security" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:wls="http://xmlns.oracle.com/weblogic/security/wls" xsi:schemaLocation="http://xmlns.oracle.com/weblogic/security/wls http://xmlns.oracle.com/weblogic/security/wls/1.0/wls.xsd http://xmlns.oracle.com/weblogic/domain http://xmlns.oracle.com/weblogic/1.0/domain.xsd http://xmlns.oracle.com/weblogic/security http://xmlns.oracle.com/weblogic/1.0/security.xsd">

    <cluster-messaging-mode>unicast</cluster-messaging-mode>
  </cluster>

补：
已在一台服务器安装weblogic，现增加一台服务器进行搭配成weblogic集群，进行重新安装配置：
（已安装配置的机器：https://blog.csdn.net/qq_37257431/article/details/144940933?spm=1001.2014.3001.5502）

在服务器1上修改配置

# 1. 进入config目录
cd /home/weblogic/oracle/middleware/user_projects/domains/base_domain/config

# 2. 备份原配置文件
cp config.xml config.xml.bak

# 3. 修改config.xml
vim config.xml

需要在config.xml中添加或修改以下内容：

<domain>
    <!-- AdminServer配置 -->
    <server>
        <name>AdminServer</name>
        <listen-address>192.168.1.101</listen-address>
        <listen-port>7001</listen-port>
    </server>

    <!-- Machine1配置 -->
    <machine>
        <name>Machine1</name>
        <node-manager>
            <name>Machine1</name>
            <listen-address>192.168.1.101</listen-address>
            <listen-port>5556</listen-port>
        </node-manager>
    </machine>

    <!-- Machine2配置 -->
    <machine>
        <name>Machine2</name>
        <node-manager>
            <name>Machine2</name>
            <listen-address>192.168.1.102</listen-address>
            <listen-port>5556</listen-port>
        </node-manager>
    </machine>

    <!-- Server1配置 -->
    <server>
        <name>Server1</name>
        <listen-address>192.168.1.101</listen-address>
        <listen-port>7003</listen-port>
        <machine>Machine1</machine>
    </server>

    <!-- Server2配置 -->
    <server>
        <name>Server2</name>
        <listen-address>192.168.1.102</listen-address>
        <listen-port>7003</listen-port>
        <machine>Machine2</machine>
    </server>
</domain>
