nacos--安装与配置

nacos--安装

一、安装

a、直接安装

从官网 下载适合版本

这里以2.0.3为例

liunx2.0.3百度网盘地址 提取码：xnvi

windows2.0.3百度网盘地址 提取码：k3uk

b、上传到服务器后解压

tar -xvf nacos-server-2.0.3.tar.gz

c、启动

cd  /nacos/bin
sh startup.sh -m standalone

二、docker安装

a、先直接启动

docker run --env MODE=standalone --name nacos -d -p 8848:8848 nacos/nacos-server

b、将镜像内/home/nacos/的配置文件导入到宿主机上

docker container cp 35e03a8c4e00:/home/nacos/ /home/

c、停止并移除当前镜像

docker stop 35e03a8c4e00 && docker rm 35e03a8c4e00

d、重新启动

2.2.3为例

docker run -d -p 8848:8848 -p 9848:9848 -p 9849:9849 --name nacos_2.2.3 \
-e MODE=standalone -e PREFER_HOST_MODE=hostname \
-e JVM_XMS=512m -e JVM_XMX=2048m \
-v /home/mount/nacos2.2.3/conf:/home/nacos/conf \
-v /home/mount/nacos2.2.3/data:/home/nacos/data \
-v /home/mount/nacos2.2.3/logs:/home/nacos/logs \
--privileged=true --restart=always nacos/nacos-server

三、docker-compose启动

a、准备挂载的目录

mkdir -p /home/nacos/logs /home/nacos/conf /home/nacos/tomcat/basedir

b、需要在挂载的conf下准备application.properties

# spring
server.servlet.contextPath=/nacos
server.contextPath=/nacos
server.port=8848
spring.datasource.platform=mysql
nacos.cmdb.dumpTaskInterval=3600
nacos.cmdb.eventTaskInterval=10
nacos.cmdb.labelTaskInterval=300
nacos.cmdb.loadDataAtStart=false
db.num=1
db.url.0=jdbc:mysql://192.168.3.87:13307/nacos2?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useSSL=false
db.user=root
db.password=Ts@20230131
### The auth system to use, currently only 'nacos' is supported:
nacos.core.auth.system.type=${NACOS_AUTH_SYSTEM_TYPE:nacos}

### The token expiration in seconds:
nacos.core.auth.default.token.expire.seconds=${NACOS_AUTH_TOKEN_EXPIRE_SECONDS:18000}

### The default token:
nacos.core.auth.default.token.secret.key=ZlcyVsvBBOF3Guu3UvsJqQRIuwe3aYra4quIhXgJ3nRdLtgL3JqnBKrA6PFfE3ejiVSn3
nacos.core.auth.plugin.nacos.token.secret.key=VGhpc0lzTXlDdXN0b65TZWNyABCLZXkwMTIzPXU2Nzg=


### Turn on/off caching of auth information. By turning on this switch, the update of auth information would have a 15 seconds delay.
nacos.core.auth.caching.enabled=${NACOS_AUTH_CACHE_ENABLE:false}
nacos.core.auth.enable.userAgentAuthWhite=${NACOS_AUTH_USER_AGENT_AUTH_WHITE_ENABLE:false}
nacos.core.auth.server.identity.key=${NACOS_AUTH_IDENTITY_KEY:serverIdentity}
nacos.core.auth.server.identity.value=${NACOS_AUTH_IDENTITY_VALUE:security}
server.tomcat.accesslog.enabled=${TOMCAT_ACCESSLOG_ENABLED:false}
server.tomcat.accesslog.pattern=%h %l %u %t "%r" %s %b %D
# default current work dir
server.tomcat.basedir=/home/nacos/tomcat/basedir
## spring security config
### turn off security
nacos.security.ignore.urls=${NACOS_SECURITY_IGNORE_URLS:/,/error,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-fe/public/**,/v1/auth/**,/v1/console/health/**,/actuator/**,/v1/console/server/**}
# metrics for elastic search
management.metrics.export.elastic.enabled=false
management.metrics.export.influx.enabled=false

nacos.naming.distro.taskDispatchThreadCount=10
nacos.naming.distro.taskDispatchPeriod=200
nacos.naming.distro.batchSyncKeyCount=1000
nacos.naming.distro.initDataRatio=0.9
nacos.naming.distro.syncRetryDelay=5000
nacos.naming.data.warmup=true

c、需要在挂载的conf下准备nacos-logback.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false" scan="true" scanPeriod="1 seconds">
    <contextName>logback</contextName>
    <property name="log.path" value="/home/nacos/logs/logback.log" />
    <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
        <!-- <filter class="com.example.logback.filter.MyFilter" /> -->
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
              <level>ERROR</level>
        </filter>
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} %contextName [%thread] %-5level %logger{36} - %msg%n
            </pattern>
        </encoder>
    </appender>
 
    <appender name="file"
        class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${log.path}</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${log.path}.%d{yyyy-MM-dd}.zip</fileNamePattern>
        </rollingPolicy>
 
        <encoder>
            <pattern>%date %level [%thread] %logger{36} [%file : %line] %msg%n
            </pattern>
        </encoder>
    </appender>
 
    <root level="debug">
        <appender-ref ref="console" />
        <appender-ref ref="file" />
    </root>

    <logger name="com.example.logback" level="warn" />
</configuration>

d、启动

version: '3'
services:
  nacos:
    image: nacos/nacos-server:v2.2.1
    container_name: nacos
    restart: always
    volumes:
      - /home/nacos/logs:/home/nacos/logs
      - /home/nacos/conf:/home/nacos/conf
      - /home/nacos/tomcat/basedir:/home/nacos/tomcat/basedir
    ports:
      - 8848:8848
      - 9848:9848
    environment:
      - PREFER_HOST_MODE=ip
      - MODE=standalone
      - SPRING_DATASOURCE_PLATFORM=mysql

四、官网推荐的docker-compose部署(prometheus/grafana等监控组件)

1、拉取仓库

git clone --depth 1 https://github.com/nacos-group/nacos-docker.git

2、运行docker-compose

cd nacos-docker
docker-compose -f example/standalone-derby.yaml up -d 

3、访问

http://ip:port/nacos

默认账号密码：nacos/nacos

五、集群

集群模式必须使用数据库

1、配置集群配置文件

在nacos的解压目录nacos/的conf目录下，有配置文件cluster.conf，请每行配置成ip:port。（请配置3个或3个以上节点）

2、首先进入conf目录下，默认只有一个cluster.conf.example文件，我们需要自行复制一份，修改名称为cluster.conf

cd /usr/local/nacos/config
cp cluster.conf.example cluster.conf

3、打开cluster.conf文件，添加集群的其他节点

#ip:port
192.168.1.120:8848
192.168.1.121:8848
192.168.1.122:8848

4、重启服务

将上面的步骤依次在其他机器上执行，或者直接将配置文件拷贝到其他机器上重启即可
