按照命令动态apache虚拟主机

httpd_Vsersion=2.4.12
DomainName=

#解析域名和绑定域名
DomainName=$1
mkdir -p /a/domains/${DomainName}/public_html
chown -R www:www /a/domains/${DomainName}/public_html
log_path=\"/a/domains/${DomainName}/public_html/${DomainName}/
errorlog=${log_path}${DomainName}-errorlog.log\"
customlog=${log_path}${DomainName}.log\"
#写入配置文件
cat > /a/apps/httpd-${httpd_Vsersion}/conf/vhosts/${DomainName}.conf <<EOF
<VirtualHost *:80>
    ServerName $1
    DocumentRoot /a/domains/${DomainName}/public_html
    ErrorLog ${errorlog}
    CustomLog ${customlog} common
</VirtualHost>
EOF
echo ${DomainName}" vhost create success , website directory : /a/domains/"${DomainName}"/public_html/"
service httpd restart
exit 1
