Nacos集群版安装部署

Nacos集群部署文档

  1. 创建文件夹
mkdir -p /application

  1. 下载 Nacos
# 下载 nacos
wget https://github.com/alibaba/nacos/releases/download/1.4.2/nacos-server-1.4.2.tar.gz
# 解压缩
tar -zxvf nacos-server-1.4.2.tar.gz
# 移动到 /application 目录
mv nacos-server-1.4.2 /application/
```

  1. 配置 Nacos

    修改 /application/nacos-server-1.4.2/conf/application.properties

    # 上下文路径
    server.servlet.contextPath=/nacos
    # 端口号
    server.port=8848
    # 本机IP地址
    nacos.inetutils.ip-address=10.2.9.150
    # 数据源
    spring.datasource.platform=mysql
    jdbc.DriverClassName=com.mysql.cj.jdbc.Driver
    # 数据源数量
    db.num=1
    # 数据源连接配置
    db.url.0=jdbc:mysql://10.2.9.151:3306/nacos_config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
    db.user=nacos
    db.password=nacos
    
    nacos.naming.empty-service.auto-clean=true
    nacos.naming.empty-service.clean.initial-delay-ms=50000
    nacos.naming.empty-service.clean.period-time-ms=30000
    
    management.metrics.export.elastic.enabled=false
    management.metrics.export.influx.enabled=false
    
    
    # Tomcat accesslog配置
    server.tomcat.accesslog.enabled=true
    
    # 日志格式
    server.tomcat.accesslog.pattern=%h %l %u %t "%r" %s %b %D %{User-Agent}i
    
    # 日志路径
    server.tomcat.basedir=/data/nacos/
    
    ### The ignore urls of auth, is deprecated in 1.2.0:
    nacos.security.ignore.urls=/,/error,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-fe/public/**,/v1/auth/**,/v1/console/health/**,/actuator/**,/v1/console/server/**
    
    # The auth system to use, currently only 'nacos' is supported:
    nacos.core.auth.system.type=nacos
    
    # If turn on auth system:
    nacos.core.auth.enabled=false
    
    ### The token expiration in seconds:
    nacos.core.auth.default.token.expire.seconds=18000
    
    ### The default token:
    nacos.core.auth.default.token.secret.key=SecretKey012345678901234567890123456789012345678901234567890123456789
    
    ### 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=true
    
    #*************** Istio Related Configurations ***************#
    ### If turn on the MCP server:
    nacos.istio.mcp.server.enabled=false
    

    修改 /application/nacos-server-1.4.2/conf/cluster.conf

10.2.9.150:8848
10.2.9.151:8848
10.2.9.152:8848
```

  1. Nacos 启动 /application/nacos-server-1.4.2/bin/startup.sh

  1. Nacos 日志清理, 保留最近十五天的日志

    编写shell脚本,自动清理日志

    
    #!/bin/bash
    
    # 初始化
    LOGS_PATH=/application/nacos-server-1.4.2/bin/logs
    
    for file in $LOGS_PATH/*
    do
        if test -f $file
        then
            echo $file
            #find $file -mtime +15 -name '*[0-9]*-[0-9]*-[0-9]*' | xargs rm -f
        else
            find $file -mtime +15 -name '*[0-9]*-[0-9]*-[0-9]*' | xargs rm -f
        fi
    done
    
    exit 0
    

添加脚本到 crontab 中, 每晚 00:00 自动执行, 清理 15 天之前的日志记录, 脚本 shell # 执行 crontab -e # 输入 1 0 * * * /data/nacos/log_rotate.sh
