1.lnmp实现多个虚拟主机，分别部署wordpress和phpmyadmin应用，并设置phpmyadmin仅能通过https协议访问；
2.配置即使客户端通过http协议访问phpmyadmin站点，最终也可以让用户使用https重新请求访问；
3.将图片保存至一台单独的服务器，上传的图片也放置于该图片服务器上；
一、环境：lnmp=Linux+Nginx+MariaDB+PHP
在Linux中配置所需必要的环境：
1.在CentOS系和RHEL系列的发行版操作系统中，本地光盘并没有提供Nginx应用程序，所以我们一般有两种方法安装：
1）.编译安装Nginx；（此项目使用安装方式）
2）.rpm安装Nginx；
???1）.编译安装： ???????编译源代码(测试环境安装，例如安装淘宝的TNginx)： ???????????1.安装好编译环境：yum -y groupinstall Development tools Server Platform Development ???????????2.可能需要提供额外的开发包： ???????????????openssl-devel（支持ssl，从而实现网站的https访问）, pcre-devel（基于正则表达式去匹配）, libevent-devel（基于事件完成数据的IO调度） ???????????3. nginx-1.12.1]# ./configure --prefix=/usr/local/nginx112 --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error_log --http-log-path=/var/log/nginx/access_log --pid-path=/var/run/nginx.pid --lock-path=/var/lock/subsys/nginx.lock --user=nginx --group=nginx --with-threads --with-file-aio --with-http_ssl_module --with-http_v2_module --with-http_dav_module --with-http_stub_status_module --with-pcre --with-stream ????????????4. ~]# make -j # && make install ???????注意：在启动nginx服务进程之前，需要创建出nginx用户和nginx组；?????????????这里是在联网环境下编译安装Nginx： ?????????????配置安装环境： ?????????????[root@chenliang ~]# yum -y groupinstall Development tools Server Platform Development ????????????????????????[root@chenliang ~]# yum -y install openssl-devel pcre-devel libevent-devel ????????????????????在指定站点下载Nginx程序的源代码包： ?????????????[root@chenliang ~]# wget -c http://nginx.org/download/nginx-1.12.0.tar.gz ?????????????解压下载的源代码包： ?????????????[root@chenliang ~]# tar xvf nginx-1.12.0.tar.gz ??????????????进入解压后的目录： ?????????????[root@chenliang ~]# cd nginx-1.12.0/ ?????????????编译： ?????????????[root@chenliang nginx-1.12.0]# ./configure --prefix=/usr/local/nginx112 --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error_log --http-log-path=/var/log/nginx/access_log --pid-path=/var/run/nginx.pid --lock-path=/var/lock/subsys/nginx.lock --user=nginx --group=nginx --with-threads --with-file-aio --with-http_ssl_module --with-http_v2_module --with-http_dav_module --with-http_stub_status_module --with-pcre --with-stream ?????????????安装： ?????????????[root@chenliang nginx-1.12.0]# make -j 4 && make install ?????????????创建Nginx用户和组： ?????????????[root@chenliang ~]# id nginx ?????????????uid=990(nginx) gid=985(nginx) 组=985(nginx) ?????????????启动Nginx服务： ?????????????语法检查： ?????????????[root@chenliang nginx-1.12.0]# nginx -t ?????????????启动： ?????????????[root@chenliang nginx-1.12.0]# nginx ?????????????查看服务启动状态： ?????????[root@chenliang ~]# ss -tnlp ?????????LISTEN ????0 ?????128 ???????????????????*:80 ????????????????????????????????*:* ??????????????????users:(("nginx",pid=3184,fd=6),("nginx",pid=3183,fd=6),("nginx",pid=3182,fd=6),("nginx",pid=3181,fd=6)) ?????????????至此，编译安装Nginx程序完成。
???2）rpm安装： ???设置对应的yum安装源，实现rpm包安装Nginx（标准化安装，大规模服务器或集群上安装，方便日后进行自动化管理）： ???????????nginx官方预制的安装包： ???????????????http://nginx.org/packages/centos/$releasever/$basearch ???????????Fedora-EPEL源中提供的安装包： ???????????????http://mirrors.sohu.com/fedora-epel/7/x86_64/Packages/n/ ???????????????????在yum源中设置添加Nginx的下载地址（需要在联网状态下进行）： ???????????????????[root@chenliang ~]# vim /etc/yum.repos.d/CentOS-Base.repo ???????????????????> ??????????[nginx] ???????????????????> ??????????name=nginx repo ???????????????????> ??????????baseurl=http://nginx.org/packages/centos/7/$basearch/ ???????????????????> ??????????gpgcheck=0 ???????????????????> ??????????enabled=1 ???????????????????[root@chenliang ~]#yum clean all ???????????????????[root@chenliang ~]#yum makecache ???????????????????安装Nginx： ???????????????????[root@chenliang ~]#yum install nginx -y ???????????????????启动Nginx服务： ???????????????????[root@chenliang ~]#nginx ???????????????????查看启动Nginx的状态（可以看到现在服务器的80端口是nginx在监听）： ???????????????????[root@chenliang ~]# ss -tnlp ???????????????????LISTEN ????0 ?????128 ?????????*:80 ??????????????????????*:* ??????????????????users:(("nginx",pid=4481,fd=6),("nginx",pid=4477,fd=6)) ???2.安装数据库环境，PHP应用程序环境： ???????????[root@chenliang ~]# yum install -y php-fpm php-mysql mariadb-server ???????????并启动相应的服务： ???????????[root@chenliang ~]# systemctl start mariadb.service ????????//启动数据库 ???????????[root@chenliang nginx-1.12.2]# systemctl start php-fpm.service ???3.防火墙和SELinux配置： ???????????????[root@chenliang ~]# getenforce ????????????????Permissive ???????????????[root@chenliang ~]# iptables -vnL ???????????????Chain INPUT (policy ACCEPT 2493 packets, 238K bytes) ????????????????pkts bytes target ????prot opt in ????out ????source ??????????????destination ????????????????????????Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) ????????????????pkts bytes target ????prot opt in ????out ????source ??????????????destination ????????????????????????Chain OUTPUT (policy ACCEPT 1837 packets, 279K bytes) ????????????????pkts bytes target ????prot opt in ????out ????source ??????????????destination ???4.在 /etc/nginx/nginx.conf 中配置Nginx基于域名的虚拟主机： ???第一台虚拟主机用来部署搭建WordPress： ???server { ???????????????????listen ??????80; ???????????????????server_name ?www.clhost1.com; ???????????????????location / { ???????????????????????????root ??/myweb/host1; ???????????????????????????index ?index.php index.html index.htm; ???????????????????} ???????????????????location ~* \.php$ { ???????????????????????root ??????????/myweb/host1; ???????????????????????fastcgi_pass ??127.0.0.1:9000; ???????????????????????fastcgi_index ?index.php; ???????????????????????fastcgi_param ?SCRIPT_FILENAME ?/myweb/host1/$fastcgi_script_name; ???????????????????????include ???????/etc/nginx/fastcgi_params; ???????????????} ???????} ???第二台虚拟主机用来搭建phpmyadmin： ???server { ???????????????????listen ??????80; ???????????????????server_name ?www.clhost2.com; ???????????????????location / { ???????????????????????????root ??/myweb/host2; ???????????????????????????index ?index.php index.html index.htm; ???????????????????} ???????????????????location ~ \.php$ { ???????????????????????????root ??????????/myweb/host2; ???????????????????????????fastcgi_pass ??127.0.0.1:9000; ???????????????????????????fastcgi_index ?index.php; ???????????????????????????fastcgi_param ?SCRIPT_FILENAME ?/myweb/host2/$fastcgi_script_name; ???????????????????????????include ???????/etc/nginx/fastcgi_params; ???????????????????} ???????????} ???????????5.创建站点首页访问路径： ???????????[root@chenliang ~]# mkdir /myweb/host{1,2} -pv ???????????mkdir: 已创建目录 "/myweb" ???????????mkdir: 已创建目录 "/myweb/host1" ???????????mkdir: 已创建目录 "/myweb/host2" ???????????创建首页文件： ???????????[root@chenliang ~]# echo "nginx‘s page1" >> /myweb/host1/index.html ???????????[root@chenliang ~]# echo "nginx‘s page2" >> /myweb/host2/index.html ???????????而后检查语法错误后启动Nginx服务： ???????????[root@chenliang ~]# nginx -t ???????????nginx: the configuration file /etc/nginx/nginx.conf syntax is ok ???????????nginx: configuration file /etc/nginx/nginx.conf test is successful ???????????[root@chenliang ~]# nginx -s reload启动各项服务后查看：[root@chenliang ~]# ss -tnlState ?????Recv-Q Send-Q ????Local Address:Port ???????????????????Peer Address:Port ?????????????LISTEN ????0 ?????128 ???????????127.0.0.1:9000 ??????????????????????????????*:* ?????????????????LISTEN ????0 ?????50 ????????????????????*:3306 ??????????????????????????????*:* ?????????????????LISTEN ????0 ?????128 ???????????????????*:80 ????????????????????????????????*:* 6.配置php-fpm：
1）配置php-fpm服务：
更改进程所有者：
[root@chenliang ~]# vim /etc/php-fpm.d/www.conf
listen = 127.0.0.1:9000 ??
user = nginx
group = nginx
2）创建访问路径：
[root@chenliang ~]# mkdir /myweb/host{1,2} -pv
mkdir: 已创建目录 "/myweb"
mkdir: 已创建目录 "/myweb/host1"
mkdir: 已创建目录 "/myweb/host2"
创建首页文件：
[root@chenliang ~]# vim /myweb/host1/index.php
nginx ??????host1‘s page.</br>
<?php
phpinfo();
$conn = mysql_connect(‘172.16.72.1‘,‘wpuser‘,‘wppass‘);
if ($conn)
echo "YES";
else
echo "NO";
?>
[root@chenliang ~]# vim /myweb/host2/index.php
nginx host2‘s page.</br>
<?php
$conn = mysql_connect(‘172.16.72.1‘,‘phpuser‘,‘phppass‘);
if ($conn)
echo "YES";
else
echo "NO";
phpinfo();
?>
7.配置数据库：
创建所需的两个数据库，授权用户并测试数据库的连接正常与否：
创建WordPress数据库：
MariaDB [(none)]> create database wpdb;
Query OK, 1 row affected (0.03 sec)
授权：
MariaDB [(none)]> grant all on wpdb. to ‘wpuser‘@‘172.16.%.%‘ identified by ‘wppass‘;
Query OK, 0 rows affected (0.10 sec)
创建PHPadmain数据库：
MariaDB [(none)]> create database phpmyadmain;
Query OK, 1 row affected (0.00 sec)
授权：
MariaDB [(none)]> grant all on phpmyadmain. to ‘phpuser‘@‘172.16.%.%‘ identified by ‘phppass‘;
Query OK, 0 rows affected (0.00 sec)
测试用来搭建WordPress数据库host1主机：
测试用来搭建PHPadmain数据库host2主机：
二、搭建虚拟主机，分别部署wordpress和phpmyadmin应用
部署wordpress：
将wordpress应用程序上传到访问目录下：
[root@chenliang host1]# ls
index.html ?index.php ?wordpress-4.2-zh_CN.tar.gz
解压：
[root@chenliang host1]# tar xf wordpress-4.2-zh_CN.tar.gz
[root@chenliang host1]# ls
index.html ?index.php ?wordpress ?wordpress-4.2-zh_CN.tar.gz
更名，为了方便键入网址：
[root@chenliang host1]# mv wordpress wp
[root@chenliang host1]# ls
index.html ?index.php ?wordpress-4.2-zh_CN.tar.gz ?wp
进入目录，修改配置文件：
[root@chenliang host1]# cd wp
[root@chenliang wp]# vim wp-config-sample.php
部署phpmyadmin：
[root@chenliang host1]# cd /myweb/host2
[root@chenliang host2]# ls
index.html ?index.php ?phpMyAdmin-3.5.4-all-languages.tar.gz
[root@chenliang host2]# tar xf phpMyAdmin-3.5.4-all-languages.tar.gz
[root@chenliang host2]# ls
index.html ?index.php ?phpMyAdmin-3.5.4-all-languages ?phpMyAdmin-3.5.4-all-languages.tar.gz
[root@chenliang host2]# mv phpMyAdmin-3.5.4-all-languages phpmyadmain
[root@chenliang host2]# ls
index.html ?index.php ?phpmyadmain ?phpMyAdmin-3.5.4-all-languages.tar.gz
[root@chenliang host2]# cd phpmyadmain/
phpmyadmin访问有时候会出现了session没有缓存的情况，要在/etc/php.ini中修改缓存路径，然后修改/var/lib/php/session的权限为nginx操作：
session.save_path = "/var/lib/php/session"
[root@chenliang phpmyadmain]# ll -d /var/lib/php/session/
drwxr-xr-x. 2 nginx nginx 6 6月 ??1 11:10 /var/lib/php/session/
lnmp下实现部署wordpress和phpmyadmin，并实现https和URL重定向
