我的第一个脚本-centos5.4-nginx-php-mysql-自动安装

由于最近买了一个burst的vps, 于是开始看些linux下的东西, 挺有意思, 开始在网上进行一些centos的设置, 并且记录在我的wiki上, 最近开始接触到脚本, 发现很强大, 省得学习时重装系统后繁琐的重复设置, 于是自己尝试写了一点, 主要为了偷懒, 而且写得十分粗燥, 不过总算在centos5.4和fedora12中测试通过.
如果安装成功, 能在最后看到各种服务的启动[OK]或是successfully, 由于不是编译安装, 所以基本不是最新版, 但应该是稳定版, 而且由于是默认安装, 以后升级也方便, 出了问题也容易google排查, 因为都是默认安装路径, 不会出现找不到文件的情况. 当然也可以选择LNMP之类的一键包, 只要有人维护, 这类包升级也方便.
OK, 安装很简单, 尽量在新装的系统中应用, 如果原先装过mysql, 则可能造成root密码为原先的密码.
1. 首先下载脚本centos.sh

2. 更改权限 chmod +x centos.sh
3. 运行./centos.sh
4. 输入mysql root的密码
5. 等待完成, 最后一排绿色[OK]和一个spawn-fcgi的successfully的字样就完成了
在fedora12和centos5.4中成功, 如果是debian或是ubuntu的话, 可能改成apt-get就行了, 暂时没有测试
