nacos單機部署

 

參考地址：https://nacos.io/zh-cn/index.html

注冊中心類似於通訊錄，可以查找到服務和服務地址的映射關系
一、安裝jdk1.8

yum install java-1.8.0-openjdk.x86_64 -y
#yum方式安裝沒有配置JAVA_HOME環境變量
cat>>/etc/profile<<EOF
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.232.b09-0.el7_7.x86_64/jre
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar
EOF
source /etc/profile

二、安裝參考官方文檔
nacos下載穩定版：
https://github.com/alibaba/nacos/releases

#解壓
unzip nacos-server-1.1.0.zip -d/usr/local/ && cd /usr/local/nacos/bin
#啟動單機模式
sh startup.sh -m standalone

[root@nacos bin]# sh startup.sh -m standalone
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.232.b09-0.el7_7.x86_64/jre/bin/java -Xms512m -Xmx512m -Xmn256m -Dnacos.standalone=true -Djava.ext.dirs=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.232.b09-0.el7_7.x86_64/jre/jre/lib/ext:/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.232.b09-0.el7_7.x86_64/jre/lib/ext:/usr/local/nacos/plugins/cmdb:/usr/local/nacos/plugins/mysql -Xloggc:/usr/local/nacos/logs/nacos_gc.log -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintGCTimeStamps -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=10 -XX:GCLogFileSize=100M -Dnacos.home=/usr/local/nacos -Dloader.path=/usr/local/nacos/plugins/health -jar /usr/local/nacos/target/nacos-server.jar --spring.config.location=classpath:/,classpath:/config/,file:./,file:./config/,file:/usr/local/nacos/conf/ --logging.config=/usr/local/nacos/conf/nacos-logback.xml --server.max-http-header-size=524288
nacos is starting with standalone
nacos is starting，you can check the /usr/local/nacos/logs/start.out

服務注冊&發現和配置管理

1、服務注冊 curl -X POST 'http://127.0.0.1:8848/nacos/v1/ns/instance?serviceName=nacos.naming.serviceName&ip=20.18.7.10&port=8080' 返回ok 2、服務發現 curl -X GET 'http://127.0.0.1:8848/nacos/v1/ns/instance/list?serviceName=nacos.naming.serviceName' 返回{"metadata":{},"dom":"nacos.naming.serviceName","cacheMillis":3000,"useSpecifiedURL":false,"hosts":[],"name":"DEFAULT_GROUP@@nacos.naming.serviceName","checksum":"a07d4655e7caf8a6aa987662a6179ad2","lastRefTime":1575104879006,"env":"","clusters":""} 3、發布配置 curl -X POST "http://127.0.0.1:8848/nacos/v1/cs/configs?dataId=nacos.cfg.dataId&group=test&content=HelloWorld" 返回true 4、獲取配置 curl -X GET "http://127.0.0.1:8848/nacos/v1/cs/configs?dataId=nacos.cfg.dataId&group=test" 返回HelloWorld 

關閉服務器
sh /usr/local/nacos/bin/shutdown.sh
