综合项目---博客

一.运行环境

192.168.32.132 Server-Web linux Web

192.168.32.133 Server-NFS-DNS linux NFS/DNS

基础配置

1.配置主机名+静态ip

2.开启防火墙并配置

3.部分开启selinux并配置

4.服务器之间通过阿里云进行时间同步

5.服务器之间实现ssh免密登录

业务需求

1.Server-web主机配置Web服务，通过域名www.opelab.com可以访问到自己建的博客网站

2.Server-NFS-DNS主机配置NFS服务，将博客网站资源共享给Server-web主机，同时配置DNS服务

二.准备工作（基本配置）

2.1.修改主机名同时进行host映射

[root@Server ~]#hostnamectl set-hostname Server-web
[root@node ~ ]#hostnamectl set-hostname Server-NFS-DNS
在两个主机中进行host映射
#vim  /etc/hosts
#reboot

2.2.配置静态ip

[root@Server-NFS-DNS ~]# nmcli c mod ens32 ipv4.method manual ipv4.address 192.168.32.133/24 ipv4.gateway 192.168.32.2 ipv4.dns 114.114.114.114
[root@Server-NFS-DNS ~]# nmcli c reload
[root@Server-NFS-DNS ~]# nmcli c up ens32

[root@Server-web ~]# nmcli c mod ens32 ipv4.method manual ipv4.address 192.168.32.132/24 ipv4.gateway 192.168.32.2 ipv4.dns 192.168.32.133
[root@Server-web ~]# nmcli c reload
[root@Server-web ~]# nmcli c up ens32

#查看DNS：[root@Server-NFS-DNS ~]# vim  /etc/sysconfig/network-scripts/ifcfg-ens32

2.3.防火墙和selinux设置

#开启防火墙，两个主机都操作
systemctl start firewalld
systemctl enable firewalld

#开启selinux,Server-web端关闭，Server-NFS-DNS端开启
关闭：setenforce 0
开启：setenforce 1

#若是开启失败，则：
[root@Server-NFS-DNS ~]#yum install selinux-policy selinux-policy-targeted -y
[root@Server-NFS-DNS ~]#vim /etc/seliux/config
SELINUX=permissive
[root@Server-NFS-DNS ~]#touch /.autorelabel
[root@Server-NFS-DNS ~]#reboot

2.4.进行阿里云时间同步

#两台主机都操作
#yum install chrony -y
#vim /etc/chrony.conf
server ntp.aliyun.com iburst
#systemctl restart chronyd
#chronyc sources -v
#timedatectl status

2.5.ssh免密登录

[root@Server-NFS-DNS ~]# ssh-keygen -t rsa
[root@Server-NFS-DNS ~]# ssh-copy-id 192.168.32.132

[root@Server-web ~]# ssh-keygen -t rsa
[root@Server-web ~]# ssh-copy-id 192.168.32.133

三.环境搭建

1.Server-web端环境搭建设置

[root@Server-web ~]#yum install nginx mariadb-server php* -y

2.Server-NFS-DNS端的环境搭建设置

博客压缩包下载链接： Release Archive | WordPress.org China 简体中文

[root@Server-NFS-DNS ~]# cd /
[root@Server-NFS-DNS ~]# unzip wordpress-6.1-zh_CN.zip

四.NFS服务搭建

1.将服务端的/wordpress目录共享给客户端192.168.32.1-web）

[root@Server-NFS-DNS ~]# yum install rpcbind -y
[root@Server-NFS-DNS ~]# yum install nfs-utils -y
[root@Server-NFS-DNS ~]# vim /etc/exports
/wordpress 192.168.32.132(rw,sync,all_squash)
#设置权限
[root@Server-NFS-DNS ~]# chmod -Rf 777 /wordpress
#防火墙放行及启动
[root@Server-NFS-DNS ~]# firewall-cmd --permanent --zone public --add-service=mountd
[root@Server-NFS-DNS ~]# firewall-cmd --permanent --zone public --add-service=rpc-bind
[root@Server-NFS-DNS ~]# firewall-cmd --permanent --zone public --add-service=nfs
[root@Server-NFS-DNS ~]# firewall-cmd --reload
[root@Server-NFS-DNS ~]# systemctl start rpcbind
[root@Server-NFS-DNS ~]# systemctl start nfs-utils
#设置zseliux的上下文文件
[root@Server-NFS-DNS ~]# ls -Z /usr/share/nginx/html
[root@Server-NFS-DNS ~]# chcon -t httpd_sys_content_t /wordpress -Rv
R代表递归修改目录，v表示显示修改提示

2.远程目录的挂载

#临时挂载
[root@Server-web ~]# yum install nfs-utils -y
[root@Server-web ~]# showmount -e 192.168.32.133
[root@Server-web ~]# mkdir -pv /wp
[root@Server-web ~]# mount -t nfs 192.168.32.133:/wordpress /wp
[root@Server-web ~]# cd /wp
[root@Server-web ~]# ll

若是想开机自动挂载，可以先查看分区的uuid,

#blkid

编辑开机自动挂载文件：

#vim /etc/fstab

UUID=6b1c1143-4556-46b9-9d44-0a60c993825e / xfs defaults 0 0

五.nginx服务搭建

[root@Server-web ~]# firewall-cmd --permanent --zone public --add-service=http
[root@Server-web ~]# firewall-cmd --permanent --zone public --add-port=80/tcp
[root@Server-web ~]# firewall-cmd --reload
[root@Server-web ~]# vim /etc/ngx/nginx.conf
[root@Server-web ~]#systemctl restart nginx

六.数据库创建和修改wordpress配置文件

启动数据库：systemctl start mariadb

[root@Server-web ~]#mysql
                  >create database wordpress;  
                  >create user 'test1'@'localhost' identified by '1234';
                  >grant all on wordpress.* to 'test1'@'localhost';  #授权
                  >exit

修改wordpress 配置文件

[root@Server-web ~]#cd /wp
[root@Server-web wp]#cp wp-config-sample.php wp-config.php
[root@Server-web wp]#vim wp-config.php

systemctl restart mariadb

systemctl restart nginx

七.使用IP地址进行测试

八.DNS服务搭建

[root@Server-NFS-DNS ~]# yum install bind -y
[root@Server-NFS-DNS ~]# firewall-cmd --permanent --zone pulic --add-servce=dns
[root@Server-NFS-DNS ~]# firewall-cmd --reload
[root@Server-NFS-DNS ~]# systemctl start named
[root@Server-NFS-DNS ~]# vim /etc/named.conf
[root@Server-NFS-DNS ~]# vim /etc/named.rfc1912.zones
[root@Server-NFS-DNS ~]# cd /var/named
[root@Server-NFS-DNS ~]# cp -a named.localhost openlab.com
[root@Server-NFS-DNS named]# vim openlab.com
[root@Server-NFS-DNS ~]# systemctl restart named
