14_部署LNMP环境、构建LNMP平台、地址重写
proxy 10.10.11.10
client 10.10.11.11
web1 10.10.11.12
web2 10.10.11.13
1.部署LNMP环境
1.1 部署nginx(前面已部署过)
1.2 部署mariadb
proxy]# yum -y install mariadb mariadb-server mariadb-devel
proxy]# systemctl start mariadb
proxy]# systemctl enable mariadb
proxy]# mysql
1.3 部署php
]# yum -y install php php-mysql php-fpm
]# systemctl start php-fpm
]# systemctl status php-fpm
]# systemctl enable php-fpm
2.构建LNMP平台
2.1 查看php-fpm配置文件(实验中不需要修改该文件)
proxy]# vim /etc/php-fpm.d/www.conf
[www]
listen = 127.0.0.1:9000 //PHP端口号
pm.max_children = 32 //最大进程数量
pm.start_servers = 15 //最小进程数量
pm.min_spare_servers = 5 //最少需要几个空闲着的进程
pm.max_spare_servers = 32 //最多允许几个进程处于空闲状态
2.2 修改Nginx配置文件支持php页面,并启动服务
proxy]# vim /etc/nginx/conf.d/default.conf
location / {
root /usr/share/nginx/html;
index index.php index.html index.htm;
}
...
location ~ \.php$ {
root /usr/share/nginx/html; #绝对路径
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
]# nginx -s reload
2.3 创建PHP测试页面,连接并查询MariaDB数据库
proxy]# vim /usr/share/nginx/html/test.php
<?php
phpinfo();
?>
client测试:
client]# firefox http://10.10.11.10/test.php
3.地址重写 (proxy)
3.1 修改配置文件(访问a.html重定向到b.html)
]# vim /etc/nginx/conf.d/default.conf
...
server_name www.a.com;
rewrite /a.html /b.html;
...
]# nginx -s reload
]# echo "aaa" > /usr/share/nginx/html/a.html
]# echo "bbb" > /usr/share/nginx/html/b.html
client测试:
]# firefox 10.10.11.10/a.html
]# firefox 10.10.11.10/b.html
3.2 访问a.html重定向到b.html(跳转地址栏)
]# vim /etc/nginx/conf.d/default.conf
...
server_name www.a.com;
rewrite /a.html /b.html redirect;
...
]# nginx -s reload
client测试:
]# firefox 10.10.11.10/a.html
3.3 修改配置文件(访问10.10.11.10的请求重定向至www.baidu.com)
]# vim /etc/nginx/conf.d/default.conf
...
server_name www.a.com;
rewrite ^/ http://www.baidu.com/;
...
]# nginx -s reload
client测试:
]# firefox 10.10.11.10
3.4 修改配置文件(访问192.168.4.5/下面子页面,重定向至www.baidu.com/下相同的页面)
]# vim /etc/nginx/conf.d/default.conf
...
server_name www.a.com;
rewrite ^/(.*)$ http://www.baidu.com/$1;
...
]# nginx -s reload
lient测试:
]# firefox 10.10.11.10/a.html
3.5 修改配置文件(实现curl和火狐访问相同链接返回的页面不同)
]# echo "I am Normal page" > /usr/share/nginx/html/test.html
]# mkdir -p /usr/share/nginx/html/firefox/
]# echo "firefox page" > /usr/share/nginx/html/firefox/test.html
]# vim /etc/nginx/conf.d/default.conf
...
location / {
root html;
index index.php index.html index.htm;
}
if ($http_user_agent ~* firefox) {
rewrite ^(.*)$ /firefox/$1;
}
...
]# nginx -s reload
client 测试:
]# firefox http://10.10.11.10/test.html
]# curl http://10.10.11.10/test.html
**********************
地址重写格式【总结】
rewrite 旧地址 新地址 [选项];
last 不再读其他rewrite
break 不再读其他语句,结束请求
redirect 临时重定向
permament 永久重定向
