一、LNMP搭建
1.官方源安装nginx
1)配置官方源
[root@web01 ~]# vim /etc/yum.repos.d/nginx.repo
[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true
#安装nginx
[root@web01 ~]# yum install -y nginx
2.设置统一用户
[root@web01 ~]# groupadd www -g 666
[root@web01 ~]# useradd www -u 666 -g 666
3.修改nginx配置文件
[root@web01 ~]# vim /etc/nginx/nginx.conf
user www;
4.启动服务并验证
[root@web01 ~]# systemctl start nginx
#设置开机自启
[root@web01 ~]# systemctl enable nginx
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.
#验证
[root@web01 ~]# ps -ef | grep nginx
5.安装php (7版本)
1)配置第三方源
[root@web01 ~]# vim /etc/yum.repos.d/php.repo
[php-webtatic]
name = PHP Repository
baseurl = http://us-east.repo.webtatic.com/yum/el7/x86_64/
gpgcheck = 0
2)卸载旧版本
[root@web01 ~]# yum remove php-mysql-5.4 php php-fpm php-common
3)安装php
1>安装方式一
#Centos7 安装源
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
[root@web01 ~]# yum -y install php71w php71w-cli php71w-common php71w-devel php71w-embedded php71w-gd php71w-mcrypt php71w-mbstring php71w-pdo php71w-xml php71w-fpm php71w-mysqlnd php71w-opcache php71w-pecl-memcached php71w-pecl-redis php71w-pecl-mongodb
2>安装方式二
#创建存放服务包的目录
[root@web01 ~]# mkdir /package
[root@web01 ~]# cd /package/
#上传包
[root@web01 /package]# rz php.tar.gz
#解压包
[root@web01 /package]# tar xf php.tar.gz
#安装本地所有rpm包
[root@web01 /package]# yum localinstall -y *.rpm
4)配置PHP
#修改用户为统一
[root@web01 ~]# vim /etc/php-fpm.d/www.conf
user = www
group = www
5.)启动服务并验证
#启动服务
[root@web01 /package]# systemctl start php-fpm
#开启自启
[root@web01 /package]# systemctl enable php-fpm
#验证服务是否启动
[root@web01 /package]# ps -ef | grep php
#查看端口
[root@web01 /package]# netstat -lntp | grep php
tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 7748/php-fpm: master
6.搭建交作业页面
1)配置nginx
[root@web01 /package]# vim /etc/nginx/conf.d/zuoye.conf
server {
listen 80;
server_name www.zuoye.com;
location / {
root /code/zuoye;
index index.html;
}
}
#创建站点目录
[root@web01 /package]# mkdir /code/zuoye -p
#上传代码
[root@web01 /package]# cd /code/zuoye/
[root@web01 /code/zuoye]# rz kaoshi.zip
[root@web01 /code/zuoye]# unzip kaoshi.zip
#修改代码内的存放文件路径
[root@web01 /code/zuoye]# vim upload_file.php
$wen="/code/zuoye/upload";
#授权
[root@web01 /code/zuoye]# chown -R www.www /code/
2)访问测试
#重启nginx服务
[root@web01 /code/zuoye]# systemctl restart nginx
#配置本地C:\Windows\System32\drivers\etc\hosts文件
10.0.0.7 www.zuoye.com
#浏览器访问www.zuoye.com
3)报错
报错405,原因是nginx作为web服务器没有办法处理post请求,我们要用php的代码,需要关联nginx和php
7.关联nginx和php
1)关联语法
#设置FastCGI服务的地址。该地址可以指定为域名或IP地址以及端口:
Syntax: fastcgi_pass address;
Default: —
Context: location, if in location
#设置参数应传递给FastCGI服务器的。该value可以包含文件,变量
Syntax: fastcgi_param parameter value [if_not_empty];
Default: —
Context: http, server, location
2)完整配置
[root@web01 /code/zuoye]# vim /etc/nginx/conf.d/default.conf
server {
listen 80;
server_name www.zuoye.com;
location / {
root /code/zuoye;
index index.html;
}
location ~* \.php$ {
#设置FastCGI服务地址
fastcgi_pass 127.0.0.1:9000;
#当访问/code/zuoye/index.php的时候,需要读取网站目录下面的.php文件,如果没有配置这一配置项时,nginx不会去网站目录下访问.php文件,所以返回空白
fastcgi_param SCRIPT_FILENAME /code/zuoye/$fastcgi_script_name;
include fastcgi_params;
}
}
3)访问页面测试(修改上传文件大小限制)
#浏览器访问www.zuoye.com
1.上传文件成功
2.413报错:文件过大,解决方式
#修改nginx上传文件大小
[root@web01 /code/zuoye]# vim /etc/nginx/nginx.conf
http {
... ...
client_max_body_size 100M;
... ...
}
[root@web01 /code/zuoye]# systemctl restart nginx
#修改php上传文件大小
[root@web01 /code/zuoye]# vim /etc/php.ini
post_max_size = 100M
upload_max_filesize = 100M
[root@web01 /code/zuoye]# systemctl restart php-fpm
8.搭建mariadb(mysql)
1)安装
#安装
[root@web01 /code/zuoye]# yum install -y mariadb-server
#安装不了需删除之前配置的php.repo
[root@web01 ~]# rm -rf /etc/yum.repos.d/php.repo
#开启并添加自启
[root@web01 /code/zuoye]# systemctl start mariadb
[root@web01 /code/zuoye]# systemctl enable mariadb
#验证
[root@web01 /code/zuoye]# netstat -lntp | grep mysql
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 9887/mysqld
2)连接
[root@web01 /code/zuoye]# mysql

+--------------------+
| Database |
+--------------------+

+--------------------+
4 rows in set (0.00 sec)
3)设置数据库密码
#设置密码
[root@web01 /code/zuoye]# mysqladmin -u root password "123"
#使用密码连接
[root@web01 /code/zuoye]# mysql -u root -p
Enter password:
9.关联php和MySQL
1)编写php测试连接数据库代码
[root@web01 /code/zuoye]# vim php_mysql.php
<?php
$servername = "localhost";
$username = "root";
$password = "123";
// 创建连接
$conn = mysqli_connect($servername, $username, $password);
// 检测连接
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
echo "小哥哥,php可以连接MySQL...";
?>

二、LNMP架构搭建wordpress
1.上传代码
#上传包
[root@web01 /code]# rz wordpress-5.0.3-zh_CN.tar.gz
#解压
[root@web01 /code]# tar xf wordpress-5.0.3-zh_CN.tar.gz
#授权
[root@web01 /code]# chown -R www.www /code
2.配置conf文件
#查看网站首页文件格式
[root@web01 /code]# ll wordpress

index index.php;
}
location ~* \.php$ {
root /code/wordpress;
fastcgi_pass 127.0.0.1:9000;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
#重启服务
[root@web01 /etc/nginx/conf.d]# systemctl restart nginx
3.访问网页
#配置本地C:\Windows\System32\drivers\etc\hosts文件
10.0.0.7 www.blog.com
#访问
www.blog.com
4.创建数据库
[root@web01 /etc/nginx/conf.d]# mysql -uroot -p123
