CentOS7——搭建LNMP环境(WordPress案例)
CentOS7——搭建LNMP环境(WordPress案例)
LNMP组成介绍
LNMP(Linux-Nginx-MySQL-PHP)网站架构是目前国际流行的Web框架,该框架包括:Linux操作系统,Nginx网络服务器,MySQL数据库,PHP编程语言,所有组成产品均是免费开源软件,这四种软件组合到一起,成为一个免费、高效的网站服务系统。
LNMP工作原理
浏览器发送http request请求到服务器(Nginx),服务器响应并处理web请求。如果是静态文本直接返回,否则将脚本(PHP)通过接口传输协议(网关协议)PHP-FCGI(fast-cgi)传输给PHP-FPM(进程管理程序),然后PHP-FPM调用PHP解析器的其中一个进程PHP-CGI来解析php脚本信息。【PHP-FPM在启动时启动了多个PHP-CGI子进程,并发执行。】然后将解析后的脚本返回到PHP-FPM,PHP-FPM再通过fast-cgi的形式将脚本信息传送给Nginx。服务器再通过Http response的形式传送给浏览器。浏览器再进行解析与渲染然后进行呈现。
WordPress介绍
WordPress 介绍 WordPress是一种使用PHP语言开发的博客平台,用户可以在支持PHP和MySQL 数据库的服务器上架设自己的网站。 也可以把WordPress 当作一个内容管理系统(CMS)来使用。 WordPress 是一个免费的开源项目,在GNU通用公共许可证下授权发布。
构建LNMP+WordPress案例
环境配置
关闭防火墙
systemctl stop firewalld systemctl disable firewalld
临时关闭SELINUX
setenforce 0
永久关闭SELINUX(重启生效)
echo SELINUX=disabled>/etc/selinux/config echo SELINUXTYPE=targeted>>/etc/selinux/config
安装Nginx
增加 Nginx 官方源
cat << EOF > /etc/yum.repos.d/nginx.repo [nginx-stable] name=nginx stable repo baseurl=http://nginx.org/packages/centos/\$releasever/\$basearch/ gpgcheck=1 enabled=1 gpgkey=https://nginx.org/keys/nginx_signing.key module_hotfixes=true [nginx-mainline] name=nginx mainline repo baseurl=http://nginx.org/packages/mainline/centos/\$releasever/\$basearch/ gpgcheck=1 enabled=0 gpgkey=https://nginx.org/keys/nginx_signing.key module_hotfixes=true EOF
EPEL 源中的 nginx.service 由于 KILL 参数问题,启动后无法停止,不建议使用。
安装Nginx
yum install -y nginx
备份Nginx配置文件

LNMP 环境测试
增加数据库
mysql -uroot -p000000 -e ‘create database wordpress;grant all privileges on wordpress.* to "localhost" identified by "wordpress_password";flush privileges;‘
增加Nginx Host设置
cat << EOF > /etc/nginx/conf.d/wordpress.conf server{ listen 8080; server_name wordpress.com; root /data/web/wordpress.com; error_log /var/log/nginx/wordpress.com_error.log; access_log /var/log/nginx/wordpress.com_access.log main; location / { try_files \$uri /index.php$is_args\$query_string; } location ~ \.php$ { root /data/web/wordpress.com; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME \$document_root\$fastcgi_script_name; include fastcgi_params; } } EOF # 重载Nginx配置 nginx -t && nginx -s reload
准备 Wordpress
mkdir -p /data/web/wordpress.com # 使用 -O 参数指定保存文件名,会强制覆盖已经存在的文件 yum -y install wget wget https://wordpress.org/latest.tar.gz -O wordpress.tar.gz tar xf wordpress.tar.gz mv wordpress/* /data/web/wordpress.com rm -rf wordpress chown -R apache:nginx /data/web/wordpress.com chmod -R 755 /data/web/wordpress.com
最后,访问http://服务器地址:8080 进入博客安装界面
如果无法访问网站地址:
1.请确保服务器的防火墙和SELINUX为关闭状态,详细操作请看基础环境配置的关闭防火墙与SELINUX操作。
2.测试主机与服务器的通信状态是否正常
1.选择语言模式为中文
2.填写数据库信息
3.填写网站信息
4.访问http://服务器地址:8080 就可以看到博客已经运行起来了
- wordpress数据库相关信息:
- 数据库服务器:localhost
- 数据库端口:3306
- 数据库名称:wordpress
- 数据库用户名:wordpress
- 数据库密码:wordpress_password
