12、总结
1、环境概述:
前几篇博客已把httpd、mysql及php以模块的方式与http进行了整合,这些服务都在一台Linux主机上部署,这种简单的架构在网站初期还能胜任,但随着网站访问量的增大,业务逻辑越来越复杂,这种架构已不能满足现实的需求,现急需优化架构。我们需要一个可扩展的网站架构,所以这次来一个大手术,httpd、mysql、以及以FastCGI方式工作的php服务各自部署在单独的服务器,三个服务各施其职,独占自己的硬件资源,这种架构随着业务量增加后扩展方便,而这种架构还实现了网站的动静分离。
所有软件包这里获取:LAMP环境所涉及软件包获取地址
2、动静分离拓扑图:
3、各服务器功能规划:
主机名 | IP地址 | 安装服务 | 说明 |
http |
192.168.0.200 |
httpd、NFS服务端 | 通过nfs把php服务器的网站程序挂载到本地,避免上传网站程序时在http和php服务器都要上传 |
php |
192.168.0.201 |
php、NFS客户端、phpmyadmin、论坛程序 | php以php-fpm方式工作,通过nfs服务把网站程序共享 |
mysql | 192.168.0.202 | mysql、配置成CA服务器 | 数据目录存放在LVM卷上,兼任CA证书服务,为实现安全的访问phpmyadmin |
4、各服务器基础环境配置:

[root@http ~] # ssh-keygen -t rsa #连续回车 [root@http ~] # ls /root/.ssh/ id_rsa id_rsa.pub [root@http ~] # ssh-copy-id root@php #在有提示处输入“yes”,l并输入php主机的密码 [root@http ~] # ls /root/.ssh/ #生成了know_hosts文件 id_rsa id_rsa.pub known_hosts [root@http ~] # ssh-copy-id root@mysql 测试http无密码访问php及mysql主机: [root@http ~] # ssh root@php Last login: Sat Jan 31 16:41:46 2015 from http [root@http ~] # ssh root@mysql Last login: Sat Jan 31 16:38:12 2015 from http |
说明:在“[root@http ~]# ssh-copy-id root@php”时,若不是指定php主机的主机名,而是指定ip地址,就像这样“[root@http ~]# ssh-copy-id root@192.168.0.201”那http登陆php时只能用指定ip的地址进行无密码登陆,如果是这样“[root@http ~]# ssh root@php”是不能无密码登陆的,通过观察“/root/.ssh/know_hosts”文件就可知道其中的道理。
4.4.2、配置php无密码访问http和mysql主机:
1
2
3
|
[root@php ~] # ssh-keygen -t rsa [root@php ~] # ssh-copy-id root@http [root@php ~] # ssh-copy-id root@mysql |
4.4.3、配置mysql无密码访问http和php主机:
1
2
3
|
[root@mysql ~] # ssh-keygen -t rsa [root@mysql ~] # ssh-copy-id root@http [root@mysql ~] # ssh-copy-id root@php |

[root@http software] # tar xf apr-util-1.5.2.tar.bz2 [root@http software] # cd apr-util-1.5.2 [root@http apr-util-1.5.2] # ./configure --prefix=/usr/local/apr-util-1.5 --with-apr=/usr/local/apr-1.5 [root@http apr-util-1.5.2] # make && make install |

|
[root@http httpd-2.4.12] # vim /etc/profile.d/http24.sh export PATH= /usr/local/apache24/bin :$PATH [root@http httpd-2.4.12] # source /etc/profile.d/http24.sh |
导出头文件:
1
|
[root@http httpd-2.4.12] # ln -sv /usr/local/apache24/include /usr/include/http24 |
导出man文档:

[root@http httpd-2.4.12] # vim /etc/man.config MANPATH /usr/man MANPATH /usr/share/man MANPATH /usr/local/man MANPATH /usr/local/share/man MANPATH /usr/X11R6/man MANPATH /usr/local/apache24/man #新增 |
配置http开机自动启动(可参照前边的博客为http提供sysv风格的脚本):
1
|
[root@http httpd-2.4.12] # echo "/usr/local/apache24/bin/apachectl -k start" >> /etc/rc.loacl |

[root@http httpd-2.4.12] # vim /etc/httpd24/extra/httpd-vhosts.conf #注释掉最后的VirtualHost容器,并新增以下两个虚拟主机 <VirtualHost *:80> DocumentRoot "/web/vhosts/bbs.linux.com" ServerName bbs.linux.com ErrorLog "logs/bbs.linux.com-error_log" CustomLog "logs/bbs.linux.com-access_log" common <Directory "/web/vhosts/bbs.linux.com" > Options none AllowOverride none Require all granted < /Directory > < /VirtualHost > <VirtualHost *:80> DocumentRoot "/web/vhosts/phpmyadmin.com" ServerName phpmyadmin.com ErrorLog "logs/phpmyadmin.com-error_log" CustomLog "logs/phpmyadmin.com-access_log" common <Directory "/web/vhosts/phpmyadmin.com" > Options none AllowOverride none Require all granted < /Directory > < /VirtualHost > |

在windows主机上用IE浏览器直接访问“http://bbs.linux.com”就可打开wordpress的安装界面,
经测试,workpress运行正常。

CA建立完成,接下来要为phpmyadmin.com这个虚拟主机提交证书申请,并为其配置成https。
9.3、回到http服务器为phpmyadmin.com虚拟主机生成私钥,生成证书签署请求,并把证书请求发给CA,:

9.6、下载CA服务器需要对外公开的证书文件(cacert.pem),导入系统后进行测试。在windows系统下需要把cacert.pem证书文件重新命令为以“crt”为后缀的文件,即改名后为“cacert.crt”,导入证书后就可以访问“https://phpmyadmin.com”进行测试。
上图是之前建的测试文件,现在用https来访问也是正常的。

现在只能用wpammin用户测试,因为root用户默认拒绝远程登陆:

用root用户来登陆phpmyadmin测试:

12、总结:
这次环境搭建比较顺利,当出现错误时都能通过程序所给出的错误提示和日志文件快速的定位到故障处在,但还是有一些地址值得注意或优化:
1、在类linux环境下对编译安装的软件包约定俗成是安装在“/usr/local/”下,这里的usr是“uinx software resource”这个目录在系统安装好后本身就会有许多文件存在,如果把我们自定义编译安装的软件都放在这个目录中,对软件的管理上还是有一些不便,这个目录有点像windows下的“Program Files”这个目录。所以建议在安装系统之初,在进行分区时可单独划出一个分区专门成为编译软件的安装目录;
2、httpd的虚拟主机的日志文件应该集中在一个地方进行集中存储管理,这次环境搭建是分散的放在各个虚拟主机主目录下,这样也不便于日志的管理;
3、因http主机上的“/web/vhosts”目录是从php主机通过nfs发布后挂载过来的,所以简化了两次上传网站程序的动作,但也在管理上带了一定的影响,当要重新启动http、php主机时要注意开关机的顺序,开机时先开php主机,再开http主机,关机时先关http主机,后关php主机。
4、这样一个LAMP环境中涉及到了“http.conf、http-ssl.conf、http-vhost.conf、my.cnf、php.ini、my-fpm.conf”等配置文件,这些配置中各个参数的具体意义得好好总结;
5、最后就是mysql这个软件,已被oracle收购,在下载mysql5.6版本包时粗略看了一下许可协议,好像不像原生的mysql了,如果是公司线上产品,用其他数据库来替代吧,mariadb是一个不错的选择(没看过它的许可)。
