實現基於NFS共享的LAMP wordpress應用

實現基於NFS共享的LAMP wordpress應用

nfs服務器端配置

//下載安裝包
yum -y install nfs-utils

//啓動服務
systemctl start nfs

//創建共享目錄
mkdir -p /data/wordpress/webdata

------------------------------
//新建編輯共享子配置文件
vim /etc/exports.d/wp.exports

//文件內容爲
/data/wordpress/webdata   192.168.26.0/24(rw)

//重啓服務
systemctl restart nfs
-------------------------------

mysql_A服務器配置

//下載安裝包
yum -y isntall mariadb-server

//安全加固，設置密碼
mysql_secure_installation

//進入數據庫
mysql

//創建服務對應庫
CREATE DATABASE wordpress；

//創建訪問數據庫用戶並授予權限
GRANT ALL ON wordpress.* TO wordpress@'192.168.26.18' IDENTIFIED BY 'wordpress';

//創建有複製權限的用戶賬戶給次聯slave使用(用於主主複製)
GRANT REPLICATION SLAVE ON *.* TO repliuser@'192.168.26.%' IDENTIFIED BY 'centos';

//刷新用戶權限
FLUSH PRIVILEGES

mysql_B服務器配置

//下載安裝包
yum -y isntall mariadb-server

//安全加固，設置密碼
mysql_secure_installation

//進入數據庫
mysql

//創建服務對應庫
CREATE DATABASE wordpress；

//創建訪問數據庫用戶並授予權限
GRANT ALL ON wordpress.* TO wordpress@'192.168.26.28' IDENTIFIED BY 'wordpress';

//創建有複製權限的用戶賬戶給次聯slave使用(用於主主複製)
GRANT REPLICATION SLAVE ON *.* TO repliuser@'192.168.26.%' IDENTIFIED BY 'centos';

//刷新用戶權限
FLUSH PRIVILEGES

wordpress_A配置

//將wordpress5.3安裝包傳進虛擬主機
wordpress-5.3-zh_CN.tar.gz

//解包到指定目錄
tar xf wordpress-5.3-zh_CN.tar.gz -C /var/www/html

//目錄授權
chown -R /var/www/html/wordpress

//下載安裝包
yum -y install php-fpm php-mysqlnd php-json httpd

//啓動服務
systemctl start httpd

//新建wordpress下存放圖片的缺失文件
mkdir /var/www/html/wordpress/wp-content/uploads

//設置開機自動掛載共享目錄
echo "192.168.26.37:/data/wordpress/webdata	/var/www/html/wordpress/wp-content/uploads	nfs	_netdev	0 0" >> /etc/fstab

//手動掛載目錄立即生效
mount 192.168.26.37:/data/wordpress/webdata /var/www/html/wordpress/wp-content/uploads
----------------------------------------
//新建編輯httpd子配置文件
vim /etc/httpd/conf.d/wp.conf

192.168.26.28   bokebi.B.org

公共設置-按步驟設置

//訪問bokebi.A.org

按正常步驟完成安裝步驟

主要注意填寫連接數據庫的地址bokebi.A.org填寫爲192.168.26.47

//按正常步驟完成安裝步驟
