第16周作业

架构题：前端有一个 LAMP 架构通过 wordpress 来部署，后端构建一个 NFS 服务器实现要求将用户上传的图片保存至后端 NFS 服务器上。

1.环境准备：

 2.一键安装wordpress脚本

准备好源码包如下：

apr-1.7.0.tar.bz2

apr-util-1.6.1.tar.bz2

httpd-2.4.41.tar.gz

mysql-5.7.31-linux-glibc2.12-x86_64.tar.gz

php-7.4.10.tar.xz

wordpress-5.4.2-zh_CN.zip

#Setp 1
#!/bin/bash
#二进制安装mysql5.7.31
COLOR="echo -e 33[01;31m"   
END='33[0m'
Wordpress_user="wpuser"  #Wordpress数据库连接用户
Wordpress_password="wppass" #Wordpress数据库连接用户密码
Wordpress_database="wordpress"  #Wordpress数据库名称

${COLOR} Setp 1 开始安装MySQL...${END}
#安装相关依赖包
yum -y install libaio numactl-libs &> /dev/null

#创建用户并解压包
groupadd mysql
useradd -r -g mysql -s /bin/false mysql

cd /usr/local/src

3.所有服务器上均安装NFS软件

[root@lamp-server ~]#yum install -y nfs-utils;systemctl start nfs-server
[root@NFS-client ~]#yum install -y nfs-utils 


#配置NFS共享文件格式
[root@lamp-server ~]#vi /etc/exports.d/wordpress.exports
/apps/httpd/htdocs/wordpress/ *(rw)

#重读配置文件，并共享目录
[root@lamp-server ~]#exportfs -r

#查看本机所有NFS共享
[root@lamp-server ~]#exportfs -v
#查看远程主机
[root@lamp-server ~]#rpcinfo -p 10.0.0.8
   program vers proto   port  service
    100000    4   tcp    111  portmapper
    100000    3   tcp    111  portmapper
    100000    2   tcp    111  portmapper

    100005    1   tcp  20048  mountd

    100005    2   tcp  20048  mountd
    100005    3   udp  20048  mountd
    100005    3   tcp  20048  mountd
    100003    3   tcp   2049  nfs
    100003    4   tcp   2049  nfs
    100227    3   tcp   2049  nfs_acl

    100021    3   tcp  37821  nlockmgr
    100021    4   tcp  37821  nlockmgr

4.在NFS-server 上安装自动挂载软件sutofs

[root@NFS-client ~]#yum install -y autofs
[root@NFS-client ~]#vi /etc/auto.master
/apps/httpd/htdocs/      /etc/auto.wordpress

[root@NFS-client ~]#vi /etc/auto.wordpress
* -fstype=nfs,vers=3 10.0.0.7:/apps/httpd/htdocs/wordpress/
[root@NFS-client ~]#systemctl restart autofs

[root@NFS-client ~]#df -T /apps/httpd/htdocs/wordpress
Filesystem                             Type 1K-blocks    Used Available Use% Mounted on
10.0.0.7:/apps/httpd/htdocs/wordpress/ nfs   39518464 4504832  35013632  12% /apps/httpd/htdocs/wordpress
#说明共享NFS服务器配置成功

5.上传图片并验证
