1. Preparation before installation
1. Download nacos-server-2.2.3 binary package
wget https://github.com/alibaba/nacos/releases/download/2.2.3/nacos-server-2.2.3.tar.gz
2. Install JDK environment (1.8 and above)
1) Use the following command to install jdk on the ubuntu system (jdk>jre>jvm, be careful to select jdk, because javac is required for startup)
apt-get install openjdk-18-jdk-headless
2) Use java -version to check the version of installed java
3) View the installed jdk directory
readlink -f /usr/bin/java | sed "s:bin/java::"
4) Configure user environment variables
echo 'JAVA_HOME=/usr/lib/jvm/java-18-openjdk-amd64' >> ~/.bashrc
source ~/.bashrc
2. Start installing Nacos
1. Download the binary file to the directory
cd /wechat
wget https://github.com/alibaba/nacos/releases/download/2.2.3/nacos-server-2.2.3.tar.gz
2. Unzip the binary package
tar -xvf nacos-server-2.2.3.tar.gz
3. Modify the decompressed nacos directory to the versioned directory nacos-2.2.3 and start nacos.
mv/wechat/nacos /wechat/nacos-2.2.3 ./bin/startup.sh -m standalone
4. Use the database to configure the Nacos environment
1) Execute mysql-schema.sql in the configuration directory conf in the application database
2) Modify the Nacos configuration file and add database configuration to application.properties under conf
spring.datasource.plateform=mysql db.num=1 db.url.0=jdbc:mysql://数据库IP:3306/app_broker?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
db.user.0=appCreator db.password.0=数据库密码 db.pool.config.connectionTimeout=30000 db.pool.config.validationTimeout=10000 db.pool.config.maximumPoolSize=20 db.pool.config.minimumIdle=2
3) Restart the Nacos service
cd /wechat/nacos-2.2.3/bin ./shutdown.sh ./startup.sh -m standalone
If the following content appears, the startup is successful. You can use ps -ef|grep nacos to check whether the process exists.
4) Access the Nacos management terminal through a browser. User authentication is not enabled by default and can be operated without logging in.

3. Turn on the user verification function when Nacos starts
1. Modify the application.properties file under conf, add and modify the following parameter configurations
nacos.core.auth.system.type=nacos #The default value of turning on user authentication switch is false. This time it needs to be changed to true nacos.core.auth.enabled=true nacos.core.auth.caching.enabled=true nacos.core. auth.enable.userAgentAuthWhite=false #Set the user authentication identity nacos.core.auth.server.identity.key=example nacos.core.auth.server.identity.value=example nacos.core.auth.plugin.nacos.token. cache.enable=false nacos.core.auth.plugin.nacos.token.expire.seconds=18000 #Set encryption key nacos.core.auth.plugin.nacos.token.secret.key=VGhpc0lzTXlDdXN0b21TZWNyZXRLZXkwMTIzNDU2Nzg=
2. Restart and use the nacos user to log in to the following link (the default password is nacos)
