用LAMP+Wordpress搭建博客
----高手一出手就是规范！！！
前言
因为之前用LNMP+wordpress搭建博客已经进行了很多次了，感觉原理已经掌握的还算可以了，就萌生了用LAMP+wordpress搭建一个博客。这个想法是在2018-5-4号出现的。5.5-5.6号正好是个星期六，星期天，于是我集两天时间，将这个想法完成。
这篇博文应该是写的还算详细，主要原因是我想给学弟看以下运维中最基本的一个服务是什么样子的，激发一下他们的学习兴趣。
太多的运维初级人员，眼高手低，总是看不起最基础的命令部分，还有一些人坐不住冷板凳，心比天高，总觉得看一下就会，没必要反复敲，重复敲。我觉得抱着这种心态的人员可以趁早的选择放弃运维，我觉得这种心态必将一事无成！
这篇博客讲的是最基础的一些内容，仅仅是用LAMP+Wordpress搭建出了一个博客而已，没有进行服务优化，比如数据库的分离，NFS的挂载，数据的备份，邮件的发送等等等。
未来还有多远，时间还有多少，前景又是怎样，不免心生焦炉，付出会成正比，一步一步走来，扬起漫天的尘埃！！！

#这一步一般用来生成 Makefile，为下一步的编译做准备，你可以通过在 configure 后加上参数来对安装进行控制，比如代码:./configure –prefix=/usr 意思是将该软件安装在 /usr 下面，执行文件就会安装在 /usr/bin （而不是默认的 /usr/local/bin),资源文件就会安装在 /usr/share（而不是默认的/usr/local/share）。同时一些软件的配置文件你可以通过指定 –sys-config= 参数进行设定。有一些软件还可以加上 –with、–enable、–without、–disable 等等参数对编译加以控制，你可以通过允许 ./configure –help 察看详细的说明帮助。

# 安装新版本的httpd软件会报以上错误，由于下载的软件版本过高，需要支持的apr系列软件版本也高，这里最好是编译安装apr软件，yum安装的时候版本一般是apr1.3.9，而此apache版本需要至少apr1.4.0及以上。下载以下三种软件包，然后编译安装，最后编译安装httpd就可以了

总结
本次搭建博客是非常愉快的，通过本次搭建学到了很多，最主要的收获是对部署Apache服务有了一个全新的认识，在部署时出现了APR错误，这个错误在以往中是没有见过的，通过这个错误，我对编译安装又有了一个全新的认识，嘿嘿嘿，肯定想不到吧，怎么Apache服务与编译安装扯上了关系吧。在部署一个服务时会牵扯到许多知识，所以很容易就会遇到自己觉得自己会了的知识，实际上还存在欠缺，这是可贵的。本次博客搭建并不算完美，存在一些瑕疵，虽不影响博客搭建，但是一个合格运维人员所不愿出现的，就是缺少优化，前言中说的有关优化在下一篇博客将会解决。
