OpenGrok on CentOS

部署安装OpenGrok {O这里是在ubuntu系统上搞的，正式环境使用的CentOS。

CentOS 上可能遇到的问题

• 依赖环境的参数不同

Building with configure (*nix including GNU/Linux)

# on Centos： diff with Fedora on python3-docutils vs. python3-docutils-doc
sudo yum install -y \
    gcc make \
    pkgconfig autoconf automake \
    python3-docutils-doc \
    libseccomp-devel \
    jansson-devel \
    libyaml-devel \
    libxml2-devel  

• centOS上默认的git版本检查git --version为git version 1.8.3.1，使用opengrok创建indexer的时候回报错——官方issue #131：seeing lots of warning messages for unknown date format with older Git

17:23:31 WARNING: GitRepository not working (missing binaries?): xxx
17:23:31 WARNING: Failed to determineCurrentVersion for xxx: java.io.IOException: fatal: unknown date format iso8601-strict

300+GB的文件……白瞎了。应该先走通最小场景再折腾，ε=(´ο｀*)))唉
