1、启动Apache，端口被占用
: AH00072: make sock: could not bind to address
(0S 10048)通常每个套接字地址(协议/网络地址/端口)只允许使用一次。: AH00072: make sock: could not bind to address 0.0.0.:443
a
AH00451: no listening sockets available, shutting dow
AH00015: Unable to open logs
解决方法：
修改Apache端口的方法：
修改文件（一般在此目录下：Apache安装目录\conf\extra）httpd-ssl.conf 、httpd.ahssl.conf，将443端口替换为你想设置的端口
再次启动httpd.exe，这次没报错，查看了重新设置的监听端口正常：
netstat -ano|findstr 端口号
2、安装gerrit过程中缺少
mysql-connector-java-5.1.21.jar、bcpkix-jdk15on-152.jar、bcprov-jdk15on-152.jar文件，下载失败
Gerrit Code Review is not shipped with MySQL Connector/J 5.1.21 ** This library is required for your configuration. ** Download and install it now [Y/n]? y Downloading http://repo2.maven.org/maven2/mysql/mysql-connector-java/5.1.21/mysql-connector-java-5.1.21.jar ...

解决方法：
从以前老gerrit上面包拷贝过来
3、缺少 "ssh-keygen"

...
解决方法：
如果有安装git，git目录下面有这个，把对应的路径添加到环境变量。如果没有，需要安装一个。
4、报错如下：
fatal: DbInjector failed
fatal: Unable to determine SqlDialect
fatal: caused by com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure
fatal: fatal: The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
fatal: caused by java.net.ConnectException: Connection refused: connect
解决方法：
应该是找不到gerrit需要的数据库或者 设置的数据库用户没有权限登录到 mysql。如果你需要使用mysql，则需要安装gerrit之前安装mysql。
5、报错如下：
fatal: DbInjector failed
fatal: Unable to determine SqlDialect fatal: caused by java.sql.SQLException: Access denied for user 'gerrit'@'localhost' (using password: YES)
解决方法：
确保安装gerrit过程中输入的数据库存在，且设置的数据库用户有权限访问数据库，如果没有权限需要添加权限：
GRANT ALL PRIVILEGES ON 数据库名.* TO '数据库用户'@'localhost' IDENTIFIED BY '用户对应的密码';
FLUSH PRIVILEGES;
6、启动gerrit报错如下：
[2024-10-31 18:03:33,281] [main] ERROR com.google.gerrit.pgm.Daemon : Unable to start daemon
com.google.inject.CreationException: Unable to create injector, see the following errors:

解决方法：
报错如上，把老的gerrit上面的ssh_host_key文件拷贝过来放到etc目录下面
7、报错如下：
[2024-10-31 18:08:44,932] [main] ERROR com.google.gerrit.pgm.Daemon : Unable to start daemon

解决方法：
网上查了，很多说按照指示reindex一下：java -jar .\bin\gerrit.war reindex
有些有作用，但是我是迁移老gerrit数据的，这种操作没有用。需要把老gerrit上面的
cache和index目录拷贝过来，再重启gerrit，就可以了。
8、启动gerrit报错如下：

老gerrit上面的是jdk1.8，而新gerrit的jdk是11，把jdk版本换成1.8就可以了。也可以使用绿色版，但是启动的时候需要带全路径。
9、Apache注册成功，但是在服务那里启动失败
解决方法：
缺少环境依赖项，例如：
没有安装:vc_redist_x64 导致的，打开链接：Apache VS17 binaries and modules download
下载vc_redist_x64并安装。
重新添加Apache为本地服务，启动服务，可以正常运行了
10、点击页面的gitweb报错如下：

看下C:\Program Files\Git\mingw64\share\gitweb\gitweb.bat 里面是否有中文的双引号，需要改成英文的双引号。
