5. Bacula配置实战
Bacula配置文件采用模块化设计，需要配置Director、Storage和File三个守护进程。from:www.itpux.com
步骤1：配置Director
# vi /etc/bacula/bacula-dir.conf
Director {
Name = fgedu-dir
DIRport = 9101
QueryFile = “/etc/bacula/scripts/query.sql”
WorkingDirectory = “/var/spool/bacula”
PidDirectory = “/var/run”
Maximum Concurrent Jobs = 20
Password = “fgedu-dir-password”
Messages = Daemon
}
Catalog {
Name = MyCatalog
dbname = “bacula”; dbuser = “bacula”; dbpassword = “bacula_password”
}
Storage {
Name = File
Address = 192.168.1.51
SDPort = 9103
Password = “fgedu-sd-password”
Device = FileStorage
Media Type = File
}
Client {
Name = fgedu-fd
Address = 192.168.1.51
FDPort = 9102
Catalog = MyCatalog
Password = “fgedu-fd-password”
File Retention = 30 days
Job Retention = 6 months
AutoPrune = yes
}
Pool {
Name = Full
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Volume Retention = 365 days
Maximum Volume Bytes = 50G
Maximum Volumes = 100
Label Format = “Full-”
}
Pool {
Name = Incremental
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Volume Retention = 30 days
Maximum Volume Bytes = 10G
Maximum Volumes = 100
Label Format = “Inc-”
}
步骤2：配置Storage Daemon
# vi /etc/bacula/bacula-sd.conf
Storage {
Name = fgedu-sd
SDPort = 9103
WorkingDirectory = “/var/spool/bacula”
Pid Directory = “/var/run”
Maximum Concurrent Jobs = 20
}
Director {
Name = fgedu-dir
Password = “fgedu-sd-password”
}
Device {
Name = FileStorage
Media Type = File
Archive Device = /backup/bacula-storage
LabelMedia = yes
Random Access = yes
AutomaticMount = yes
RemovableMedia = no
AlwaysOpen = no
Maximum Concurrent Jobs = 5
}
Messages {
Name = Standard
director = fgedu-dir = all
}
步骤3：配置File Daemon
# vi /etc/bacula/bacula-fd.conf
Director {
Name = fgedu-dir
Password = “fgedu-fd-password”
}
FileDaemon {
Name = fgedu-fd
FDport = 9102
WorkingDirectory = /var/spool/bacula
Pid Directory = /var/run
Maximum Concurrent Jobs = 20
}
Messages {
Name = Standard
director = fgedu-dir = all, !skipped, !restored
}
6. 备份作业配置实战
配置完成后，创建备份作业定义和计划。
步骤1：定义文件集
# vi /etc/bacula/bacula-dir.conf
FileSet {
Name = “Linux-Full-Set”
Include {
Options {
signature = MD5
compression = GZIP
noatime = yes
}
File = /etc
File = /home
File = /var/log
File = /var/spool
File = /fgedudb
}
Exclude {
File = /var/log/bacula
File = /var/spool/bacula
File = /proc
File = /sys
File = /dev
File = /tmp
}
}
FileSet {
Name = “Database-Set”
Include {
Options {
signature = MD5
compression = GZIP
}
File = /backup/mysql
File = /backup/oracle
}
}
步骤2：定义备份作业
# vi /etc/bacula/bacula-dir.conf
JobDefs {
Name = “DefaultJob”
Type = Backup
Level = Incremental
Client = fgedu-fd
FileSet = “Linux-Full-Set”
Schedule = “WeeklyCycle”
Storage = File
Messages = Standard
Pool = Incremental
Priority = 10
Write Bootstrap = “/var/spool/bacula/%c.bsr”
}
Job {
Name = “Backup-fgedu”
JobDefs = “DefaultJob”
Client = fgedu-fd
FileSet = “Linux-Full-Set”
Pool = Full
Full Backup Pool = Full
Incremental Backup Pool = Incremental
}
Job {
Name = “Backup-Database”
JobDefs = “DefaultJob”
FileSet = “Database-Set”
Schedule = “DailyBackup”
Pool = Full
Level = Full
}
Job {
Name = “Restore-fgedu”
Type = Restore
Client = fgedu-fd
FileSet = “Linux-Full-Set”
Storage = File
Pool = Full
Messages = Standard
Where = /restore
}
步骤3：定义调度计划
# vi /etc/bacula/bacula-dir.conf
Schedule {
Name = “WeeklyCycle”
Run = Full 1st sun at 23:00
Run = Differential 2nd-5th sun at 23:00
Run = Incremental mon-sat at 23:00
}
Schedule {
Name = “DailyBackup”
Run = Full daily at 02:00
}
Schedule {
Name = “MonthlyFull”
Run = Full on 1 at 00:00
}
步骤4：启动服务并验证
# systemctl start bacula-dir
# systemctl start bacula-sd
# systemctl start bacula-fd
# 设置开机自启
# systemctl enable bacula-dir
# systemctl enable bacula-sd
# systemctl enable bacula-fd
# 验证服务状态
# systemctl status bacula-dir

7. 生产环境最佳实践
在生产环境中部署Bacula需要考虑性能优化、安全加固和监控告警。
性能优化配置
# vi /etc/bacula/bacula-dir.conf
Director {
Name = fgedu-dir
DIRport = 9101
Maximum Concurrent Jobs = 50
Maximum Connections = 100
…
}
# 优化Storage配置
# vi /etc/bacula/bacula-sd.conf
Storage {
Name = fgedu-sd
SDPort = 9103
Maximum Concurrent Jobs = 50
Maximum Connections = 100
…
}
Device {
Name = FileStorage
Maximum Concurrent Jobs = 10
Maximum Block Size = 20M
Minimum Block Size = 512K
…
}
安全加固配置
# vi /etc/bacula/bacula-dir.conf
Director {
Name = fgedu-dir
…
TLS Enable = yes
TLS Require = yes
TLS CA Certificate File = /etc/bacula/certs/ca.crt
TLS Certificate = /etc/bacula/certs/director.crt
TLS Key = /etc/bacula/certs/director.key
}
# 配置防火墙规则
# firewall-cmd –permanent –add-port=9101/tcp
# firewall-cmd –permanent –add-port=9102/tcp
# firewall-cmd –permanent –add-port=9103/tcp
# firewall-cmd –reload
# 输出案例如下：
success
监控与告警配置
# vi /etc/bacula/bacula-dir.conf
Messages {
Name = Standard
mailcommand = “/usr/sbin/bsmtp -h smtp.fgedu.net.cn -f \”\(Bacula\) \<%r\>\” -s \”Bacula: %t %e of %c %l\” %r”
operatorcommand = “/usr/sbin/bsmtp -h smtp.fgedu.net.cn -f \”\(Bacula\) \<%r\>\” -s \”Bacula: Intervention needed for %j\” %r”
mail = admin@fgedu.net.cn = all, !skipped
operator = admin@fgedu.net.cn = mount
console = all, !skipped, !saved
append = “/var/log/bacula/bacula.log” = all, !skipped
catalog = all
}
# 配置日志轮转
# vi /etc/logrotate.d/bacula
/var/log/bacula/*.log {
weekly
rotate 12
compress
delaycompress
missingok
notifempty
create 0640 bacula bacula
}
