部署PHP

# 1.卸载Linux自带的旧版本php
[root@web01 ~]# yum remove php-mysql-5.4 php php-fpm php-common

# 2.添加php第三方源
[root@nginx ~]# 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

# 3.安装php
[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

# 4.创建用户
[root@web01 ~]# groupadd www -g 666
[root@web01 ~]# useradd www -u 666 -g 666 -s /sbin/nologin -M

# 5.修改nginx运行用户
[root@web01 ~]# vim /etc/nginx/nginx.conf
user www;

php-fpm作用：用来管理php程序运行
## php相关配置文件
/etc/php-fpm.conf      # php管理进程配置文件
/etc/php.ini      # php程序配置文件
/etc/php-fpm.d/www.conf  # php管理进程的子配置文件

# 6.修改php的启动用户
[root@web01 ~]# vim /etc/php-fpm.d/www.conf
[www]
user = www 
group = www

# 7.启动php并加入开机自启
[root@web01 ~]# systemctl start php-fpm
[root@web01 ~]# systemctl enable php-fpm

# 8.检查php进程和端口
[root@web01 ~]# ps -ef|grep php
root        856      1  0 15:17 ?        00:00:00 php-fpm: master process (/etc/php-fpm.conf)
www         893    856  0 15:17 ?        00:00:00 php-fpm: pool www
www         894    856  0 15:17 ?        00:00:00 php-fpm: pool www
www         895    856  0 15:17 ?        00:00:00 php-fpm: pool www
www         896    856  0 15:17 ?        00:00:00 php-fpm: pool www
www         897    856  0 15:17 ?        00:00:00 php-fpm: pool www
root       1167   1139  0 15:23 pts/0    00:00:00 grep --color=auto php

[root@web01 ~]# netstat -lntup|grep php
tcp        0      0 127.0.0.1:9000          0.0.0.0:*               LISTEN      856/php-fpm: master

配置nginx连接php

[root@web01 movie]# vim /etc/nginx/conf.d/movie.conf

server{
 listen 80;
 server_name movie.yjt.com;

 location /{
  root /movie;
  index index.php index.html;
 }

 location ~ \.php$ {
  root /movie;
  ## nginx调用本机的9000端口（php-fpm程序）
  fastcgi_pass 127.0.0.1:9000;
  ## 用php程序，解析哪个目录下的哪个.php的文件
  fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
  ## 包含php变量的文件
  include /etc/nginx/fastcgi_params;
  
 }
}

#授权
[root@web01 movie]# chown www.www /movie/
[root@web01 movie]# ll -ld
drwxr-xr-x 2 www www 102 Jun  7 15:26 .

## 去Windows改域名

部署wordpress

# 1.编辑nginx配置文件
[root@web01 conf.d]# vim /etc/nginx/conf.d/blog.yjt.com.conf
server{
 listen 80;
 server_name blog.yjt.com;
 root /blog/wordpress;

 location /{
  index index.php index.html;
 }

 location ~ \.php$ {
  fastcgi_pass 127.0.0.1:9000;
  fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
  include /etc/nginx/fastcgi_params;
  
 }
}

# 2 重新加载nginx
[root@web01 conf.d]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

[root@web01 conf.d]# systemctl reload nginx

# 3.测试nginx连接php（编写php info代码）
[root@web01 conf.d]# vim /blog/info.php
<?php
    phpinfo();
?>

# 4.创建站点目录并授权
[root@web01 ~]# mkdir /blog/wordpress
[root@web01 wordpress]# chown -R www.www /blog/wordpress/

# 5.windows域名解析
打开路径：C:\Windows\System32\drivers\etc 编辑hosts文件
10.0.0.7 blog.yjt.com

# 6.打开浏览器访问：http://blog.zls.com/info.php

# 7.下载wordpress代码
wordpress官网：https://wordpress.org/
[root@web01 blog]# wget https://cn.wordpress.org/latest-zh_CN.tar.gz

# 8.解压代码
[root@web01 blog]# tar xf latest.tar.gz 

# 9.修改nginx配置文件
[root@web01 blog]# vim /etc/nginx/conf.d/blog.yjt.com.conf 
server{
 listen 80;
 server_name blog.yjt.com;
 root /blog/wordpress;

 location /{
  index index.php index.html;
 }

 location ~ \.php$ {
  fastcgi_pass 127.0.0.1:9000;
  fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
  include /etc/nginx/fastcgi_params;
  
 }
}

# 10.重新加载nginx
[root@web01 blog]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

[root@web01 blog]# systemctl reload nginx

# 11.打开浏览器，访问：http://blog.yjt.com/

修改nginx上传

[root@web01 nginx]# vim /etc/php.ini

0M表示无限制大小

[root@web01 nginx]# systemctl reload php-fpm.service 

[root@web01 ~]# vim /etc/nginx/nginx.conf

[root@web01 nginx]# systemctl reload ngin

优化php

## 启动php服务时，创建php.sock安全套接字文件，该文件的属主和属组
listen = /opt/php.sock
listen.owner = www
listen.group = www

### 完整php配置文件
[www]
user = www 
group = www
;listen = 0.0.0.0:9000   ### (在php配置文件中；是注释的意思)
listen = /opt/php.sock
listen.owner = www
listen.group = www
listen.allowed_clients = 127.0.0.1
pm = dynamic
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 35
slowlog = /var/log/php-fpm/www-slow.log
php_admin_value[error_log] = /var/log/php-fpm/www-error.log
php_admin_flag[log_errors] = on
php_value[session.save_handler] = files
php_value[session.save_path] = /var/lib/php/session
php_value[soap.wsdl_cache_dir] = /var/lib/php/wsdlcache

    fastcgi_pass unix:/opt/php.sock;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
  }
}

# 2.重新加载nginx
