系统配置
本章讲述的是$site_path/etc/xxx.config的配置内容。该目录下配置了系统运行的各种参数，系统重启将会生效。
配置文件采用HJSON格式，这也是git配置文件采用的格式，因此你可以很方便的在shell中使用git config命令来设置值，如：git config -f "./gerrit.config" database.type "mysql"，当然平时使用文本编辑器来修改配置值即可。文件格式大体如：
[gerrit]
basePath = git
canonicalWebUrl = http://localhost:8080/gerrit/
[database]
type = mysql
hostname = localhost
database = reviewdb
username = gerrit

系统配置
系统配置项记录在$site_path/etc/gerrit.config文件中，该文件也可用于配置插件参数。
以下示例文件配置了域名、数据库、下载命令、ldap登录、邮件、打印java日志、打印web请求日志、gitiles（需安装gitiles.jar插件）、代码合并方式改为rebase、链接识别（changeid、bugzilla、redmine、邮件）：
[gerrit]
basePath = git
canonicalWebUrl = http://www.example.com/gerrit/
installCommitMsgHookCommand = curl -Lo .git/hooks/commit-msg www.example.com/gerrit/tools/hooks/commit-msg && chmod +x .git/hooks/commit-msg

保密配置
$site_path'/etc/secure.config配置文件将覆盖$site_path'/etc/gerrit.config的配置，该文件应该是只读的，用于配置密码等敏感信息。示例：
[auth]
registerEmailPrivateKey = 2zHNrXE2bsoylzUqDxZp0H1cqUmjgWb6
[database]
username = webuser
password = s3kr3t
[ldap]
password = l3tm3srch
[httpd]
sslKeyPassword = g3rr1t
[sendemail]
smtpPass = sp@m
[remote "bar"]
password = s3kr3t
