Gerrit升级实践：从2.15.x升级至3.2.x

内容导读

互联网集市收集整理的这篇技术教程文章主要介绍了Gerrit升级实践：从2.15.x升级至3.2.x，小编现在分享给大家，供广大互联网技能从业者学习和参考。文章包含22803字，纯文字阅读大概需要33分钟。

内容图文

本文实践Gerrit从2.15.7升级至3.2.3。

Gerrit在2.16.x版本以后，数据库结构发生了变化，不再使用Postgres，而是使用了NoteDB；所以 Gerrit从2.15.x升级到3.x以上，需要由2.15.x过度到2.16.x，然后再升级到3.x版本。

其中Changes数据需要通过手动方式从ReviewDB迁移，Account和Group数据由Gerrit在执行init时自动迁移。

升级准备

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


* 清空插件目录

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


**升级至Gerrit 2.16.15**
Gerrit 2.15.7升级到2.16.15，执行命令前，需要完成升级准备阶段的工作。

**停止Gerrit 2.15.7**

docker stop cicd-gerrit215-service


**检测Gerrit版本**

java -jar review_site/bin/gerrit.war version


**手动执行升级**

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.txt

**修改配置文件**
执行上一步migrate-to-note-db命令后，将在/data/cicd/gerrit/review_site/etc/目录下生成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


**获取需要升级的Gerrit**
用2.16.15版本的gerrit.war替换review_site/bin目录下的gerrit.war。注意gerrit.war的执行权限、属主和属组与原本的一致。

**检测Gerrit版本**

java -jar review_site/bin/gerrit.war version


**初始化需要升级的Gerrit**

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

非容器方式运行：

前台运行

review_site/bin/gerrit.sh start

后台运行

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


**升级至Gerrit 3.2.3**
Gerrit 2.16.15升级到3.2.3，执行命令前，需要完成升级准备阶段的工作。

**停止Gerrit 2.16.15**

docker stop cicd-gerrit216-service


**检测Gerrit版本**

java -jar review_site/bin/gerrit.war version


**手动执行升级**

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升级至3.x以上时，请参考Gerrit部署实践：冷备方案/自动备份中的gerrit.config和secure.config，修改这2个配置文件。同时修改：

vi review_site/etc/notedb.config

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


**获取需要升级的Gerrit**
用3.2.3版本的gerrit.war替换review_site/bin目录下的gerrit.war。注意gerrit.war的执行权限、属主和属组与原本的一致。

**检测Gerrit版本**

java -jar review_site/bin/gerrit.war version


**初始化需要升级的Gerrit**

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

**运行Gerrit实例**

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

单行命令

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


**异常处理**
**异常现象：change X has no note_db_state**
异常现象：Gerrit 2.5.7 -> Gerrit 2.16.15: change X has no note_db_state; rebuild it first.

解决方法：

宿主机上执行

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

手动执行迁移

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

从日志中获取迁移出错的数据

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

删除数据库中异常数据，可使用Shell脚本批量删除或者直接从数据库中删除

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

再次执行手工迁移

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

执行初始化

[root@server gerrit]# java -jar review_site/bin/gerrit.war init --batch --install-all-pl
