這几天進graylog時提示6版已經出來了
看官網說的是可以直接更新
還是先裝一台來試看看好了
這次用的是almalinux 9
6版已經不再支援 elasticsearch 了
依照官網安裝流程裝到opensearch就有問題了
安裝後無法啟動
看了一下 opensearch.yml
裡面有一段
######## Start OpenSearch Security Demo Configuration ########

######## End OpenSearch Security Demo Configuration ########
感覺是這段的問題
備分後重新開一個新的 opensearch.yml
裡面的內容只要以下這些就好
cluster.name: graylog
node.name: ${HOSTNAME}
path.data: /var/lib/opensearch
path.logs: /var/log/opensearch
discovery.type: single-node
network.host: 0.0.0.0
action.auto_create_index: false
plugins.security.disabled: true
indices.query.bool.max_clause_count: 32768
改完後啟動就沒問題了
跟之前不同 graylog這個版本安裝好後
打開 http://127.0.0.1:9000 無法進到web介面
看了一下 /var/log/graylog-server/server.log
It seems you are starting Graylog for the first time. To set up a fresh install, a setup interface has
been started. You must log in to it to perform the initial configuration and continue.
Initial configuration is accessible at 0.0.0.0:9000, with username 'admin' and password 'iIcCiFzjWY'.
Try clicking on http://admin:iIcCiFzjWY@0.0.0.0:9000
需要先 Initial configuration 才能使用
進入後依照畫面的步驟設定後 就能進入graylog的介面了
Memory/Heap usage 預設是1G 要再調整
/etc/sysconfig/graylog-server
GRAYLOG_SERVER_JAVA_OPTS="-Xms1g -Xmx1g -server -XX:+UseG1GC -XX:-OmitStackTraceInFastThrow"
依ram大小調整
