### Nacos 部署

#### 一. Docker 方式部署

##### 1. 安装 Docker 环境

    bash <(curl -sSL https://dwz.cn/XOJj0Njx) -i docker
    bash <(curl -sSL https://dwz.cn/XOJj0Njx) -i compose

##### 2. Docekr 单机模式部署(embedded)

    cd nacos-standalone
    docker-compose up -d

##### 3. Docekr 集群部署(embedded)

    cd nacos-cluster-embedded
    docker-compose up -d

##### 4. Docekr 集群部署(mysql)

    cd nacos-cluster-mysql
    docker-compose up -d

#### 二. 虚拟机方式部署

##### 1. 安装 JDK 环境

    # 创建 jdk 安装目录
    mkdir -p /usr/java

    # 下载解压 jdk 安装包
    curl --progress-bar https://oss.hc-yun.com/mango_soft/jdk-8u211-linux-x64.tar.gz | tar xz -C /usr/java

    # 配置 jdk 环境变量
    cat > /etc/profile.d/jdk.sh <<'EOF'
    export JAVA_HOME=/usr/java/jdk1.8.0_211
    export JRE_HOME=${JAVA_HOME}/jre
    export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib:$CLASSPATH
    export PATH=$JAVA_HOME/bin:$PATH
    EOF

##### 2. 单机模式部署(embedded)

    # 下载解压 nacos 安装包
    curl --progress-bar https://ghproxy.com/https://github.com/alibaba/nacos/releases/download/2.2.0/nacos-server-2.2.0.tar.gz | tar xz -C /home

    # 创建 nacos 服务
    source /etc/profile.d/jdk.sh
    cat > /usr/lib/systemd/system/nacos.service <<EOF
    [Unit]
    Description=nacos
    After=network.target

    [Service]
    Type=forking

    ExecStop=/home/nacos/bin/shutdown.sh
    MemoryLimit=2048M
    Restart=always
    RestartSec=10

    [Install]
    WantedBy=multi-user.target
    EOF

    # 启动 nacos 服务 && 配置 nacos 服务开机自启动
    systemctl daemon-reload
    systemctl enable --now nacos.service

### 监控 nacos

[Nacos 监控手册](https://nacos.io/zh-cn/docs/v2/guide/admin/monitor-guide.html)

#### 1. Nacos 暴露 metrics 数据

    sed -i '/management.endpoints.web.exposure.include/s/^#//' /home/nacos/conf/application.properties

#### 2. 修改 prometheus 配置, 采集 Nacos metrics 数据

    # example 1
    metrics_path: '/nacos/actuator/prometheus'
    static_configs:
      - targets:
        - 192.168.10.71:8848
        - 192.168.10.72:8848
        - 192.168.10.73:8848

    # example 2
    metrics_path: '/nacos/actuator/prometheus'
    static_configs:
      - targets: ['192.168.10.71:8848','192.168.10.72:8848','192.168.10.73:8848']

#### 3. Nacos grafana监控模版
