1. gerrit的安裝
前提：已安裝好java環境，mysql環境，nginx環境
1) 建立gerrit資料庫，并自定義編碼為utf8
# mysql -u root
mysql>create database gerritdb CHARACTER SET utf8 COLLATE utf8_general_ci;
mysql>grant all on gerritdb.* to 'gerrit'@'localhost' identified by 'gerritpass';
**Note**: gerritpass是密碼
2）建立使用者gerrit
# useradd gerrit
# passwd gerrit
3) 下載下傳gerrit war包，到目錄/home/gerrit/
下載下傳link :
https://www.gerritcodereview.com/2.16.html
下載下傳版2.16.6
4) 切換到使用者gerrit, 安裝gerrit
java -jar gerrit-2.16.6.war init -d ~/gerrit_site
除了選用mysql資料庫，Verified，http認證代理，下載下傳mysql-connector-java-5.1.10.jar，bcpkix-jdk15on-151.jar 其他的都是預設！

Initialized /home/gerrit/gerrit_site
2. gerrit的配置
1）切換到root, 修改/home/gerrit/gerrit_site/etc/gerrit.config配置檔案
将gerrit端口改為8082，因為預設端口8080被tomcat占用。
canonicalWebUrl = http://${centosip}:8082/
[httpd]
listenUrl = http://*:8082/
2) 啟動gerrit
# /home/gerrit/gerrit_site/bin/gerrit.sh start
Starting Gerrit Code Review: OK
檢視gerrit占用端口:
netstat -ltpn | grep -i gerrit
3) 設定gerrit開機啟動
未完待續
3. Nginx反向代理配置
https://blog.csdn.net/Coder80/article/details/48176559
a. 在root使用者下面，輸入下面的指令：
# cd /etc/nginx/conf.d
建立一個 gerrit.conf 檔案，用來處理gerrit的反向代理, 配置如下内容：
server {
listen 88;
server_name localhost;
location / {
auth_basic “Gerrit Code Review”;
auth_basic_user_file /home/gerrit/review2/etc/passwords;
proxy_pass http://127.0.0.1:8082;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $host;
}
}
b. 重新開機nginx, gerrit服務, 檢視端口占用：
4. 建立認證權限（也就是登陸gerrit的時候輸入的使用者）
注意：第一次加-c參數是為了建立密碼檔案，預設第一個使用者是系統管理者
htpasswd -c /home/gerrit/gerrit_site/etc/passwords gerrit
htpasswd /home/gerrit/gerrit_site/etc/passwords jenkins
檢視下認證賬号檔案資訊
cat /home/gerrit/gerrit_site/etc/passwords
重新開機nginx服務
nginx -s reload
可通過http://ip:88 和http://ip:8082打開gerrit頁面, 用gerrit登入（管理者）：
note: 必須先用88端口打開gerrit， 否則會報Configuration error的錯
5. 配置gitweb
在前面章節已經安裝了gitweb， 下面對gitweb進行配置：
git config --file /home/gerrit/review2/etc/gerrit.config gitweb.cgi /var/www/git/gitweb.cgi
git config --file /home/gerrit/review2/etc/gerrit.config --unset gitweb.url
重新開機gerrit，然後登陸gerrit後，gitweb超連結效果就有了
6. Issues
issue 1: xxx is not in the sudoers file.This incident will be reported
solution:
1.切換到root使用者下
2./etc/sudoers檔案預設是隻讀的，對root來說也是，是以需先添加sudoers檔案的寫權限,指令是:
chmod u+w /etc/sudoers
3.編輯sudoers檔案
vi /etc/sudoers
找到這行 root ALL=(ALL) ALL,在他下面添加xxx ALL=(ALL) ALL (這裡的xxx是你的使用者名)
ps:這裡說下你可以sudoers添加下面四行中任意一條
youuser ALL=(ALL) ALL
%youuser ALL=(ALL) ALL
youuser ALL=(ALL) NOPASSWD: ALL
%youuser ALL=(ALL) NOPASSWD: ALL
第一行:允許使用者youuser執行sudo指令(需要輸入密碼).
第二行:允許使用者組youuser裡面的使用者執行sudo指令(需要輸入密碼).
第三行:允許使用者youuser執行sudo指令,并且在執行的時候不輸入密碼.
第四行:允許使用者組youuser裡面的使用者執行sudo指令,并且在執行的時候不輸入密碼.
Issue 2: Starting Gerrit Code Review: FAILED
https://www.cnblogs.com/kevingrace/p/5624122.html
檢視log ， /home/gerrit/review2/logs/error_log
issue 3: fatal: caused by java.sql.SQLException: Access denied for user ‘gerrit’@‘localhost’ (using password: YES)
Solution:
a. Please make user you can login to mysql with command: mysql -u gerrit -p
If it shows Access denied for user ‘gerrit’@‘localhost’ (using password: YES)
b. Please update the password for gerrituser:
mysqladmin -ugerrit -p o l d p a s s w o r d p a s s w o r d ′ oldpassword password ' oldpasswordpassword′newpassword’
such as :
mysqladmin -ugerrit -pgerrit123 password gerrit123!
Then, it should be ok to login to mysql with the newpassword
Issue 4: htpasswd: command not found
Solution:
yum install -y httpd
Issue 5: Configuration Error: Check the HTTP server’s authentication settings.
Solution:
https://blog.csdn.net/Coder80/article/details/48176559
gerrit和nginx占用了相同的端口号80
修改nginx監聽端口:
Gerrit: 8082
Nginx:80
Nginx監聽gerrit：88 （反向代理）
issue 6: 啟動nginx失敗 bind() to 0.0.0.0:8088 failed (13: Permission denied)
Solution:
nginx -c /etc/nginx/nginx.conf
issue 7: The branch ‘master’ does not exist on the given remote ‘gerrit’. If
these changes are intended to start a new branch, re-run with the ‘-R’
option enabled.
Solution:
the failed caused by the creating project in gerrit with non-empty project
issue 8: mysqladmin: connect to server at ‘localhost’ failed
Solution:
https://blog.csdn.net/zl17/article/details/8589454
use mysql;
update user set password=PASSWORD(“gerrit123!”)where user=“gerrit”;
更改密碼為 newpassord
flush privileges; 更新權限
quit 退出
issue 9: the command failed for failed: grant all on gerritdb.* to ‘gerrit’@‘slave1’ identified by ‘gerritpass’;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘identified by ‘gerritpass’’ at line 1

issue10: install gerrit failed， ＂Unable to load authentication plugin ‘caching_sha2_password’.＂
fatal: DbInjector failed
fatal: Unable to determine SqlDialect
fatal: caused by java.sql.SQLException: Unable to load authentication plugin ‘caching_sha2_password’.
Solution:
https://zhuanlan.zhihu.com/p/48263574
一、建立了一個新使用者，并指定加密規則為mysql_native_password：
CREATE USER ‘your username’@’%’ IDENTIFIED WITH mysql_native_password BY 'your password;
或者修改使用者加密方式
ALTER USER ‘root’@‘localhost’ IDENTIFIED WITH mysql_native_password BY ‘root’;
二、将預設密碼規則設定為mysql_native_password，重新整理權限并重置root密碼。
default_authentication_plugin=mysql_native_password
issue 11: install gerrit failed, “Unknown system variable ‘tx_isolation’”
Solution:
Update jdbc version to 8.x.x as mysql is updated to 8.x.x
that is : mysql-connector-java-8.0.xx.jar
issue 12: install gerrit failed: Loading class com.mysql.jdbc.Driver'. This is deprecated. The new driver class is
com.mysql.jdbc.Driver'. This is deprecated. The new driver class is
Solution:
Download the latest version of gerrit, such as gerrit-3.0.1.war, which use mysql-connector-8.0.x.jar
