此次搭建graylog日志平台，使用到的组件有mongo、elasticsearch、kafka、zookeeper、graylog、filebeat，下面总结一下搭建过程：
一、部署mongo集群(单机版也可以)
1、时间同步
安装ntpdate,添加定时任务同步时间
最好所有机器都配置时间同步
yum install ntpdate -y cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime # crontab -e 5 * * * * ntpdate -u ntp.ntsc.ac.cn
2、yum安装mongo
配置仓库源并安装vim /etc/yum.repos.d/mongodb-org.repo [mongodb-org-4.2] name=MongoDB Repository baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/4.2/x86_64/ gpgcheck=1 enabled=1 gpgkey=https://www.mongodb.org/static/pgp/server-4.2.asc yum -y install mongodb-org
启动mongo并设置开机自启
systemctl daemon-reload systemctl enable mongod.service systemctl start mongod.service3、集群模式专有配置（单机版可以忽略此步） 修改配置文件设置副本集
# vim /etc/mongod.conf
# mongod.conf
# for documentation of all options, see:
# http://docs.mongodb.org/manual/reference/configuration-options/
# where to write logging data.

初始化副本集
> use admin;
switched to db admin
> rs.initiate( {
... _id : "graylog-rs",
... members: [
... { _id: 0, host: "192.168.1.10:27017"},
... { _id: 1, host: "192.168.1.11:27017"},
... { _id: 2, host: "192.168.1.12:27017"}
... ]
... })
确认副本集状态
rs.status()
"members" : [
{
"_id" : 0,
"name" : "192.168.1.10:27017",
"health" : 1,
"state" : 1,
"stateStr" : "PRIMARY",
"uptime" : 623,
"optime" : {
"ts" : Timestamp(1621748878, 1),
"t" : NumberLong(1)
},
"optimeDate" : ISODate("2021-05-23T13:47:58Z"),
"syncingTo" : "",
"syncSourceHost" : "",
"electionTime" : Timestamp(1621748728, 1),
"electionDate" : ISODate("2021-05-23T13:45:28Z"),
"configVersion" : 1,
"self" : true,
"lastHeartbeatMessage" : ""
},
{
"_id" : 1,
"name" : "192.168.1.11:27017",
"health" : 1,
"state" : 2,
"stateStr" : "SECONDARY",
"uptime" : 162,
"optime" : {
"ts" : Timestamp(1621748728, 1),
"t" : NumberLong(1)
},
"optimeDurable" : {
"ts" : Timestamp(1621748728, 1),
"t" : NumberLong(1)
},
"optimeDate" : ISODate("2021-05-23T13:45:28Z"),
"optimeDurableDate" : ISODate("2021-05-23T13:45:28Z"),
"lastHeartbeat" : ISODate("2021-05-23T13:45:28.690Z"),
"lastHeartbeatRecv" : ISODate("2021-05-23T13:45:28.288Z"),
"pingMs" : NumberLong(0),
"lastHeartbeatMessage" : "",
"syncingTo" : "192.168.1.10:27017",
"syncSourceHost" : "192.168.1.10:27017",
"syncSourceId" : 0,
"infoMessage" : "",
"configVersion" : 1
},
{
"_id" : 2,
"name" : "192.168.1.12:27017",
"health" : 1,
"state" : 2,
"stateStr" : "SECONDARY",
"uptime" : 162,
"optime" : {
"ts" : Timestamp(1621748728, 1),
"t" : NumberLong(1)
},
"optimeDurable" : {
"ts" : Timestamp(1621748728, 1),
"t" : NumberLong(1)
},
"optimeDate" : ISODate("2021-05-23T13:45:28Z"),
"optimeDurableDate" : ISODate("2021-05-23T13:45:28Z"),
"lastHeartbeat" : ISODate("2021-05-23T13:45:28.690Z"),
"lastHeartbeatRecv" : ISODate("2021-05-23T13:45:28.286Z"),
"pingMs" : NumberLong(0),
"lastHeartbeatMessage" : "",
"syncingTo" : "192.168.1.10:27017",
"syncSourceHost" : "192.168.1.10:27017",
"syncSourceId" : 0,
"infoMessage" : "",
"configVersion" : 1
}
]
生成 keyFile 文件，拷贝到其它节点，在第一台PRIMARY节点执行
openssl rand -base64 756 > /var/lib/mongo/access.key chown -R mongod.mongod /var/lib/mongo/access.key chmod 600 /var/lib/mongo/access.key scp -r /var/lib/mongo/access.key 192.168.1.11:/var/lib/mongo/ scp -r /var/lib/mongo/access.key 192.168.1.12:/var/lib/mongo/拷贝完成后，需要修改配置文件
集群搭建到此结束。
4、创建用户
创建管理员用户 随便找一台机器执行即可use admin
db.createUser({user: "admin", pwd: "Admin_123456", roles: ["root"]})
db.auth("admin","Admin_123456")
创建用于graplog连接的用户
use graylog
db.createUser({
user: "graylog",
pwd: "Graylog_123456",
"roles" : [{
"role" : "dbOwner",
"db" : "graylog"
}, {
"role" : "readWrite",
"db" : "graylog"
}]
})
开启安全认证配置，三台机器都需要如此设置，然后重启服务
# vim /etc/mongod.conf #添加如下配置 security: keyFile: /var/lib/mongo/access.key #单机mongo不用加这行 authorization: enabledsystemctl restart mongod 5、验证 1、登陆是否能认证成功 2、副本集状态是否正常 到此mongo集群副本集部署好了。
