一、iscsi网络存储
1.1 配置FreeNAS
考虑专业的磁盘柜价格不菲，而使用服务器的方式一方面磁盘容量有限，另一方面IO的性能也很难保障。FreeNAS是一套免费的NAS服务器，它能将一部普通PC变成网络存储服务器。用户可通过Windows、Macs、FTP、SSH 及网络文件系统 (NFS) 来访问存储服务器。
我们通过它来组建符合企业使用的备份存储设备，该系统具体的安装步骤可参考相关资源。这里通过启用iscsi功能实现网络备份存储，相关设置如下图。
1.2 配置iscsi客户端
iSCSI的服务器端已经在FreeNAS上完成配置，接下来需要在linux系统上完成客户端的配置，实现在客户端对网络存储的挂载。
首先安装相关的系统组件并完成配置文件的修改。
yum -y install iscsi-initiator-utils vi /etc/iscsi/initiatorname.iscsi InitiatorName=iqn.2016-06.com.redhat:82367514497d#客户端的标记
接下来修改主要的配置文件。
vi /etc/iscsi/iscsid.conf
node.session.auth.authmethod = CHAP#根据freenas的设置修改 node.session.auth.username = myj.5.199 node.session.auth.password = testtesttest discovery.sendtargets.auth.authmethod = CHAP#根据freenas的设置修改 discovery.sendtargets.auth.username = backup.myj discovery.sendtargets.auth.password = testtesttest
完成设置后通过以下指令查看配置和连接情况。
iscsiadm -m discovery -t sendtargets -p 192.168.5.199 iscsiadm -m node -o show
1.3 配置开机自动挂载
完成iSCSI的配置后，接下来配置开机自动挂载及相应的服务自动启动设定，具体系统分区操作略。
systemctl enable iscsid.service iscsiadm -m node -T iqn.2005-10.org.freenas.ctl:backu-10ttarget -p 192.168.5.199 --op update -n node.startup -v automatic Ls -l /dev/disk/by-uuid Blkid /dev/sdc1
二、备份存储设置
2.1 配置bacula-dir.conf

AutomaticMount = yes; # when device opened, read it
RemovableMedia = no;
AlwaysOpen = no;
Maximum Concurrent Jobs = 5
}
三、图形界面配置
bacula默认的安装是字符界面（其实也有基于QT环境的GUI界面，考虑性能和所依赖的安装包太多，没有使用）。第三方的工具有基于WEB的界面报告，基本上可以满足日常需要。
3.1 安装相关组件
yum install httpd php php-gd php-gettext php-mysql php-pdo systemctl enable httpd.service systemctl start httpd.service firewall-cmd --permanent --add-port=80/tcp firewall-cmd --reload cd /var/www/html curl -O http://www.bacula-web.org/files/bacula-web.org/downloads/bacula-web-latest.tgz mkdir -v /var/www/html/bacula tar -xzf bacula-web-latest.tgz -C /var/www/html/bacula chown -Rv apache: /var/www/html/bacula cd application/config cp -v config.php.sample config.php chown -v apache: config.php
3.2 配置文件
vi config.php
$config['language'] = 'en_EN'; $config[0]['label'] = 'Backup Server'; $config[0]['host'] = 'localhost'; $config[0]['login'] = 'bacula'; $config[0]['password'] = 'verystrongpassword'; $config[0]['db_name'] = 'bacula'; $config[0]['db_type'] = 'mysql'; $config[0]['db_port'] = '3306';
vi /etc/php.ini
