• graylog安装


    官网:http://docs.graylog.org/en/2.4/pages/installation/os/centos.html

    Prerequisites

    Taking a minimal server setup as base will need this additional packages:

    $ sudo yum install java-1.8.0-openjdk-headless.x86_64
    

    If you want to use pwgen later on you need to Setup EPEL on your system with sudo yum install epel-release and install the package with sudo yum install pwgen.

    MongoDB

    Installing MongoDB on CentOS should follow the tutorial for RHEL and CentOS from the MongoDB documentation. First add the repository file /etc/yum.repos.d/mongodb-org-3.6.repo with the following contents:

    [mongodb-org-3.6]
    name=MongoDB Repository
    baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.6/x86_64/
    gpgcheck=1
    enabled=1
    gpgkey=https://www.mongodb.org/static/pgp/server-3.6.asc
    

    After that, install the latest release of MongoDB with sudo yum install -y mongodb-org.

    Additionally, run these last steps to start MongoDB during the operating system’s boot and start it right away:

    $ sudo chkconfig --add mongod
    $ sudo systemctl daemon-reload
    $ sudo systemctl enable mongod.service
    $ sudo systemctl start mongod.service

    查看是否启动成功:

      查找/var/log/mongodb/mongod.log 的末尾是否为:    [initandlisten] waiting for connections on port <port>

    Elasticsearch

    Graylog 2.4.x should be used with Elasticsearch 5.x, please follow the installation instructions from the Elasticsearch installation guide.

    First install the Elastic GPG key with rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearchthen add the repository file /etc/yum.repos.d/elasticsearch.repo with the following contents:

    [elasticsearch-5.x]
    name=Elasticsearch repository for 5.x packages
    baseurl=https://artifacts.elastic.co/packages/5.x/yum
    gpgcheck=1
    gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
    enabled=1
    autorefresh=1
    type=rpm-md
    

    followed by the installation of the latest release with sudo yum install elasticsearch.

    Make sure to modify the Elasticsearch configuration file (/etc/elasticsearch/elasticsearch.yml) and set the cluster name to graylog additionally you need to uncomment (remove the # as first character) the line:

    cluster.name: graylog
    

    After you have modified the configuration, you can start Elasticsearch:

    $ sudo chkconfig --add elasticsearch
    $ sudo systemctl daemon-reload
    $ sudo systemctl enable elasticsearch.service
    $ sudo systemctl restart elasticsearch.service
    

    Graylog

    Now install the Graylog repository configuration and Graylog itself with the following commands:

    $ sudo rpm -Uvh https://packages.graylog2.org/repo/packages/graylog-2.4-repository_latest.rpm
    $ sudo yum install graylog-server
    

    Follow the instructions in your /etc/graylog/server/server.conf and add password_secret and root_password_sha2. These settings are mandatory and without them, Graylog will not start!

    password_secret的长度不得小于16个字符,可以使用 命令: pwgen -N 1 -s 96      生成其值

    You need to use the following command to create your root_password_sha2:

    echo -n yourpassword | sha256sum
    

    To be able to connect to Graylog you should set rest_listen_uri and web_listen_uri to the public host name or a public IP address of the machine you can connect to. More information about these settings can be found in Configuring the web interface.

    Note

    If you’re operating a single-node setup and would like to use HTTPS for the Graylog web interface and the Graylog REST API, it’s possible to use NGINX or Apache as a reverse proxy.

    The last step is to enable Graylog during the operating system’s startup:

    $ sudo chkconfig --add graylog-server
    $ sudo systemctl daemon-reload
    $ sudo systemctl enable graylog-server.service
    $ sudo systemctl start graylog-server.service
    
    

    SELinux information

    Hint

    We assume that you have policycoreutils-python installed to manage SELinux.

    If you’re using SELinux on your system, you need to take care of the following settings:

    • Allow the web server to access the network: sudo setsebool -P httpd_can_network_connect 1

    • If the policy above does not comply with your security policy, you can also allow access to each port individually:
      • Graylog REST API and web interface: sudo semanage port -a -t http_port_t -p tcp 9000
      • Elasticsearch (only if the HTTP API is being used): sudo semanage port -a -t http_port_t -p tcp 9200
    • Allow using MongoDB’s default port (27017/tcp): sudo semanage port -a -t mongod_port_t -p tcp 27017

    If you run a single server environment with NGINX or Apache proxy, enabling the Graylog REST API is enough. All other rules are only required in a multi-node setup. Having SELinux disabled during installation and enabling it later, requires you to manually check the policies for MongoDB, Elasticsearch and Graylog.
