博客系统

三种配置:php+nginx+mysql

搭建步骤

hostnamectl set-hostname lnmp

先检查CD有没有挂载
[root@localhost ~]# mount /dev/cdrom /media             #挂载
mount: /dev/sr0 is write-protected, mounting read-only
[root@localhost ~]# vi /etc/yum.repos.d/local.repo
进入之后:
[rhel]
name=rhel
baseurl=file:///media
enabled=1
gpgcheck=0
保存退出
[root@localhost ~]# yum clean all          #清理环境
[root@localhost ~]# yum repolist           #检索yum包
[root@localhost ~]# yum -y install unzip   #下载解压工具
[root@localhost ~]# ls                     #查看压缩包
anaconda-ks.cfg  lnmp.zip  wordpress-4.7.3-zh_CN.zip
[root@localhost ~]# unzip lnmp.zip         #解压
[root@localhost ~]# unzip wordpress-4.7.3-zh_CN.zip
再次进入:
[root@localhost ~]# vi /etc/yum.repos.d/local.repo
进入之后:
[rhel]
name=rhel
baseurl=file:///media
enabled=1
gpgcheck=0
[lnmp]
name=lnmp
baseurl=file:///root/lnmp/lnmp
enabled=1
gpgcheck=0
保存退出
[root@localhost ~]# yum clean all          #清理环境
[root@localhost ~]# yum repolist           #检索yum包,此时已有lnmp包
下载服务:
[root@localhost ~]# yum -y install nginx mariadb-server php  php-mysql php-fpm


[root@localhost ~]# vi /etc/nginx/conf.d/default.conf
进入之后:需要修改的可自行与下对比
location / {
              root   /usr/share/nginx/html;
              index  index.php  index.html index.htm;    #这行加个index.php
          }

#30-36行注释去掉，修改以下两处参数
查看行数方法:按ESC,输入":",输入set nu ,回车即可
群体去掉#方法:光标移至30行#处,按Ctrl+v,下键选中至36行,按d即可删除
 location ~ \.php$ {
              root           /usr/share/nginx/html;   #改html为/usr/share/nginx/html
             fastcgi_pass   127.0.0.1:9000;
             fastcgi_index  index.php;
             fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;   #改/scripts为$document_root
             include        fastcgi_params;
          }
保存退出
[root@localhost ~]# systemctl start nginx   #启动nginx


[root@localhost ~]# systemctl start mariadb
[root@localhost ~]# mysql_secure_installation
然后回车(第二次进入需要输入密码)
y
设置密码
重复输入密码

[root@localhost ~]# mysql  -uroot -p000000（密码为你设置的）

[root@localhost ~]# cd wordpress/
[root@localhost wordpress]# cp -ar * /usr/share/nginx/html/

[root@localhost html]# chmod  -R 777 ./
[root@localhost html]# systemctl start php-fpm
[root@localhost html]# systemctl enable php-fpm
Created symlink from /etc/systemd/system/multi-user.target.wants/php-fpm.service to /usr/lib/systemd/system/php-fpm.service.


[root@localhost ~]# netstat -ntpl
有一下三个即可:
->  3306:mysqld
->  9000:php-fpm
->  80:nginx


如果要进行服务访问,则需要关闭防火墙才可进行访问;
命令为: systemctl stop firewalld  （关闭防火墙并不安全）
查看防火墙状态命令: systemctl status firewalld
打开防火墙命令为: systemctl start firewalld
如果不想关闭防火墙服务,可使用firewall-cmd命令添加规则;

查看链接(https://www.cnblogs.com/zhengyan6/p/15602877.html) 关于firewall-cmd的使用

直接关闭SElinux即可:[root@localhost ~]# setenforce 0
但是并不安全,实验无妨
如果为了安全可进入配置文件进行修改:
vi /etc/nginx/conf.d/default.conf
location / {
              root   /usr/share/nginx/html;
              index  index.php  index.html index.htm;
          } #配置文件中的内容
 index  index.php  index.html index.htm  #上下文要一致
semanage fcontext -a -t httpd_sys_content_t '/usr/share/nginx/html/index.php(/.*)?'
restorecon  -RFv /usr/share/nginx/html/index.php

输入:http://192.168.100.10(此ip应为自己虚拟机ip)即可
