本文實踐Gerrit從2.15.7升級至3.2.3。java

Gerrit在2.16.x版本之後，數據庫結構發生了變化，再也不使用Postgres，而是使用了NoteDB；因此 Gerrit從2.15.x升級到3.x以上，須要由2.15.x過分到2.16.x，而後再升級到3.x版本。git

其中Changes數據須要經過手動方式從ReviewDB遷移，Account和Group數據由Gerrit在執行init時自動遷移。web

升級準備sql

rm -rf /data/cicd/gerrit/review_site/logs/*docker

* 清空插件目錄

rm -rf /data/cicd/gerrit/review_site/plugins/*數據庫

**升級至Gerrit 2.16.15**
Gerrit 2.15.7升級到2.16.15，執行命令前，須要完成升級準備階段的工做。

**中止Gerrit 2.15.7**

docker stop cicd-gerrit215-servicetcp

**檢測Gerrit版本**

java -jar review_site/bin/gerrit.war versionide

**手動執行升級**

When you run ‘migrate-to-note-db‘ command, you must have to set ‘–-threads’ as small as possible. If you don’t set it, a migration process creates too many threads to make connections to a database and you will see error message ‘ you can’t make a connection to database’

java -jar review_site/bin/gerrit.war migrate-to-note-db --threads 3 -d review_site/ 2>&1 | tee /tmp/notedb.txtpost

**修改配置文件**
執行上一步migrate-to-note-db命令後，將在/data/cicd/gerrit/review_site/etc/目錄下生成notedb.config文件。修改notedb.config文件：

vi review_site/etc/notedb.config

[noteDb "changes"]
autoMigrate = false
trial = false
write = true
read = true
sequence = true
primaryStorage = note db
disableReviewDb = true

**獲取須要升級的Gerrit**
用2.16.15版本的gerrit.war替換review_site/bin目錄下的gerrit.war。注意gerrit.war的執行權限、屬主和屬組與本來的一致。

**檢測Gerrit版本**

java -jar review_site/bin/gerrit.war version

**初始化須要升級的Gerrit**

java -jar review_site/bin/gerrit.war init --batch --install-all-plugins -d review_site/

非容器方式運行：

前臺運行

review_site/bin/gerrit.sh start

後臺運行

java -jar review_site/bin/gerrit.war daemon -d review_site/

**升級至Gerrit 3.2.3**
Gerrit 2.16.15升級到3.2.3，執行命令前，須要完成升級準備階段的工做。

**中止Gerrit 2.16.15**

docker stop cicd-gerrit216-service

**檢測Gerrit版本**

java -jar review_site/bin/gerrit.war version

**手動執行升級**

java -jar review_site/bin/gerrit.war migrate-to-note-db --threads 3 -d review_site/ 2>&1 | tee /tmp/notedb.txt

**修改配置文件**
2.16.x升級至3.x以上時，請參考Gerrit部署實踐：冷備方案/自動備份中的gerrit.config和secure.config，修改這2個配置文件。同時修改：

vi review_site/etc/notedb.config

[noteDb "changes"]
autoMigrate = false
trial = false
write = true
read = true
sequence = true
primaryStorage = note db
disableReviewDb = true

**獲取須要升級的Gerrit**
用3.2.3版本的gerrit.war替換review_site/bin目錄下的gerrit.war。注意gerrit.war的執行權限、屬主和屬組與本來的一致。

**檢測Gerrit版本**

**運行Gerrit實例**

docker run \
--name cicd-gerrit-service \
--restart always \
--network host \
-e DOCKER_HOST=tcp://<HOST-IP>:2375 \
-v "/var/run/docker.sock:/var/run/docker.sock:rw" \
-v "/data/cicd/gerrit/review_site:/var/gerrit/review_site" \
-d openfrontier/gerrit:3.2.3-1

單行命令

docker run --name cicd-gerrit-service --restart always --network host -e DOCKER_HOST=tcp://192.168.122.32:2375 -v "/var/run/docker.sock:/var/run/docker.sock:rw" -v "/data/cicd/gerrit/review_site:/var/gerrit/review_site" -d openfrontier/gerrit:3.2.3-1

**異常處理**
**異常現象：change X has no note_db_state**
異常現象：Gerrit 2.5.7 -> Gerrit 2.16.15: change X has no note_db_state; rebuild it first.

解決方法：

宿主機上執行

[root@server gerrit]# cd /data/cicd/gerrit

手動執行遷移

When you run ‘migrate-to-note-db‘ command, you must have to set ‘–threads’ as small as possible.

If you don’t set it, a migration process creates too many threads to make connections to a

database and you will see error message ‘ you can’t make a connection to database’

[root@server gerrit]# java -jar review_site/bin/gerrit.war migrate-to-note-db --treads 3 -d review_site/ 2>&1 | tee /tmp/notedb.txt

從日誌中獲取遷移出錯的數據

[root@server gerrit]# cat /tmp/notedb.txt | grep 'has no note_db_state' | awk '{print $3}'

刪除數據庫中異常數據，可以使用Shell腳本批量刪除或者直接從數據庫中刪除

SELECT FROM changes WHERE change_id = 15937
SELECT FROM change_messages WHERE change_id = 15937

修改/etc/notedb.config

[root@server gerrit]# vi etc/notedb.config
[noteDb "changes"]
autoMigrate = false
trial = false
write = true
read = true
sequence = true
primaryStorage = NOTE_DB
disableReviewDb = true
primaryStorage = review db
disableReviewDb = false
