shell：数据库备份脚本+自动搭建论坛

数据库备份脚本
1.执行db_dump.sh westos(数据库密码)
2.脚本执行后会备份数据库中的所有库到/mnt/mysqldump目录中
3.备份文件名称为 “库名称.sql”当此文件存在时报错并询问动作：输入“S”跳过备份，当输入“B"时备份“库名称.sql”文件为 “库名称_backup.sql”,当输入“O”时，覆盖源文件。

#!/bin/bash
ECHO(){
	echo -e "\033[$1m$2\033[0m"
}
[ -n "$1" ] ||{
	ECHO 31 "Please input the password"
	exit
}
rpm -q mariadb-server.x86_64 &>/dev/null ||{
	ECHO 31 "Please install mariadb-server.x86_64"
	exit
}
[ -e "/mnt/mysqldump" ] &>/dev/null ||{
	mkdir -p /mnt/mysqldump/
}
mysql -uroot -p$1 -e "SHOW DATABASES;" &>/dev/null 
if [ $? = 0 ]
then
	for DATA in `mysql -uroot -p$1 -e "SHOW DATABASES;"| grep -Ev "information_schema|performance_schema|Database"`
	do

	[ -e "/mnt/mysqldump/$DATA.sql" ] &&{
		ECHO 31 "$DATA is exist!!!"
		read -p "Please input action S|B|O: " ACTION
		case $ACTION in 
			s|S)
			;;
			b|B)
			mv /mnt/mysqldump/$DATE.sql /mnt/mysqldump/"$DATA"_backup.sql
			mysql -uroot -p$1 $DATA > /mnt/mysqldump/$DATA.sql
			ECHO 32 ""

			ECHO 31 "Please input right action!!!"

		esac
}||{
        mysqldump -uroot -p$1 $DATA >/mnt/mysqldump/$DATA.sql
        ECHO 32 "$DATA is created"
}
done

自动搭建论坛
执行脚本lamp.sh
脚本执行后部署好论坛，并设定apache的网络接口为8080

#!bin/bash
 
echo "1.软件安装"
dnf install httpd mariadb-server php php-mysqlnd -y
 
echo "2.关闭防火墙"
systemctl stop firewalld
systemctl disable firewalld
 
echo "3.关闭selinux"
setenforce 0
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/sysconfig/selinux
 
echo "4.启动服务并设为开机自启动"
systemctl start httpd
systemctl start mariadb
systemctl enable  httpd
systemctl enable mariadb
 
echo "5.下载wordpress并解压发布"
#wget https://cn.wordpress.org/wordpress-4.9.4-zh_CN.tar.gz
#tar xf wordpress-4.9.4-zh_CN.tar.gz -C /var/www/html
 
echo "6.Apache端口更改"
sed -i "s/Listen 80/Listen 8080/g" /etc/httpd/conf/httpd.conf
systemctl restart httpd
 
echo "7.测试论坛/博客是否搭建成功"
curl http://127.0.0.1:8080 | grep "论坛" &>/dev/null
[ $? -eq 0 ] && echo "lamp搭建成功" || echo “lamp搭建失败”
