### 创建用户 ###

useradd -s /sbin/nologin cerebro

### 解压安装文件 ###

mkdir /opt/cerebro;\
    tar xf /tmp/cerebro-0.8.1.tgz -C /opt/cerebro;\
    ln -s /opt/cerebro/cerebro-0.8.1 /opt/cerebro/current;\
    chown -R cerebro. /opt/cerebro

### 更改配置 ###

*  auth.settings  
    访问Cerebro的用户名及密码
 *  hosts  
    要监控的Elasticsearch集群，host:节点访问地址，name:标识，一般用ES的cluster\_name

mkdir /home/cerebro/data;\
    chown -R cerebro. /home/cerebro;\
    tee /opt/cerebro/current/conf/application.conf << 'EOF'
    secret="ki:s:[[@=Ag?QI`W2jMwkY:eqvrJ]JqoJyi2axj3ZvOv^/KavOT4ViJSv?6YY4[N"
    basePath="/"
    pidfile.path="/opt/cerebro/current/cerebro.pid"
    data.path="/home/cerebro/data/cerebro.db"
    es={
        gzip=true
    }
    auth={
        type: basic
        settings: {
            username="admin"
            password="Admin_2018"
        }
    }
    hosts=[
      {
        host="http://192.168.1.141:9200"
        name="es_log"
      }
    ]
    EOF

### 创建服务 ###

tee /etc/systemd/system/cerebro.service << 'EOF'
    [Unit]
    Description=Cerebro
    After=network.target
    
    [Service]
    Type=folking
    PIDFile=/opt/cerebro/current/cerebro.pid
    User=cerebro
    Group=cerebro
    LimitNOFILE=65535
    ExecStart=/opt/cerebro/current/bin/cerebro -Dconfig.file=/opt/cerebro/current/conf/application.conf
    Restart=on-failure
    WorkingDirectory=/opt/cerebro/current
    
    [Install]
    WantedBy=multi-user.target
    EOF

### 启动 ###

systemctl daemon-reload;\
    systemctl enable cerebro;\
    systemctl start cerebro;\
    systemctl status cerebro

### 开启防火墙 ###

firewall-cmd --add-port=9000/tcp --permanent ;\
    firewall-cmd --reload

### 访问 ###

默认端口为9000，若需要修改端口

*  port  
    暴露的端口
 *  address  
    默认为0.0.0.0，设置为0.0.0.0表示对该主机所有网卡开放

tee -a /etc/systemd/system/cerebro.service << 'EOF'
    http = {
        port = "9000"
        address = "192.168.1.144"
    }
    EOF
