centos7安装graylog
1.准备环境，安装mongodb
yum install epel-release -y yum install pwgen -y
yum -y install java
vim /etc/profile
# JAVA配置
JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH
source /etc/profile
java -version
which java
vim /etc/yum.repos.d/mongodb-org-3.6.repo
[mongodb-org-4.0] name=MongoDB Repository baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/4.0/x86_64/ gpgcheck=1 enabled=1 gpgkey=https://www.mongodb.org/static/pgp/server-4.0.asc
2.安装elasticsearch
yum install -y mongodb-org systemctl enable mongod systemctl start mongod rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
vim /etc/yum.repos.d/elasticsearch.repo
[elasticsearch-6.x] name=Elasticsearch repository for 6.x packages baseurl=https://artifacts.elastic.co/packages/6.x/yum gpgcheck=1 gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch enabled=1 autorefresh=1 type=rpm-md
yum install elasticsearch # 修改配置，设置JAVA_HOME vim /etc/sysconfig/elasticsearch ----------------------------------------------------------------
# 填上自己的java_home路径,可以用which java获得路径
JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk
# 启动elasticsearch
systemctl enable elasticsearch
systemctl start elasticsearch
3.安装Groylog
rpm -Uvh https://packages.graylog2.org/repo/packages/graylog-3.0-repository_latest.rpm
yum install graylog-server -y
修改配置， password_secret和root_password_sha2是必须的，不设置则无法启动，设置方法如下：
pwgen -N 1 -s 96 # passworde_secret可以通过命令：pwgen -N 1 -s 96 来随机生成 echo -n admin | sha256sum # admin用户密码生成命令：echo -n admin | sha256sum # 生成后，请记住你的 YourPassword vim /etc/graylog/server/server.conf
修改/etc/graylog/server/server.conf配置如下
password_secret = 6Z06fZHU2DwuOf9X8fhnvphCd3OM7oqwLECRRcejvjpieSvVtwu08yHYHIKDi56bAxRvtCOZ3xKKiBqyt00XYCgVa0oETB0L root_password_sha2 = e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855 # admin用户邮箱(可以不写) root_email = "root@example.com" # 时区（要写） root_timezone = Asia/Shanghai # elasticsearch 相关配置 elasticsearch_hosts = http://127.0.0.1:9200 elasticsearch_shards =1 elasticsearch_replicas = 0 # mongodb 连接配置，这里直接本机起的mongodb，没有设置验证 mongodb_uri = mongodb://localhost/graylog # 电子邮件smtp,设置为自己的邮箱smtp服务（这段可以不写） transport_email_enabled = true transport_email_hostname = smtp.exmail.qq.com transport_email_port = 465 transport_email_use_auth = true transport_email_use_tls = false transport_email_use_ssl = true transport_email_auth_username = root@example.com transport_email_auth_password = 123456 transport_email_subject_prefix = [graylog] transport_email_from_email = root@example.com transport_email_web_interface_url = http://graylog.example.com # 网络访问相关，重要，graylog3比2.x版本简洁了很多网络配置，只需配置http_bind_address即可。 http_bind_address = 0.0.0.0:9000 # 配置外网地址，我这里用了域名+nginx做反向代理，所以外网地址如下。没有的话就直接就用外网ip+port，如：http://外网ip:9000/ http_publish_uri = http://graylog.example.com/ # http_external_uri = http://graylog.example.com/ 单节点的话，此配置不需要配置，默认使用http_publish_uri
---------------------------------------------------------------------------------
# 启动需要手动设置Java路径 vim /etc/sysconfig/graylog-server --------------------------------------------------------------------------------- JAVA=/usr/local/jdk1.8.0_191/bin/java --------------------------------------------------------------------------------- # 启动服务 $ systemctl enable graylog-server $ systemctl start graylog-server

附言：本文相对于参考文件来说，整理了一下格式，只做了前半部分自己需要的地方。参考文件中有关于如何安装jdk环境的，测试了一下，直接下载没有影响到后面，当然可能是因为我只做前半部分。
