Firebird是一种关系型数据库管理系统，它使用SQL（结构化查询语言）进行数据操作。与许多其他数据库系统相比，Firebird以其卓越的性能、稳定性和可扩展性而著称。
在Ubuntu下安装firebird
在Linux下使用apt search查找firebird，看到很多相关软件包：
apt search firebird

使用apt install 安装firebird
sudo apt install firebird-dev firebird3.0-server firebird3.0-examples
或者
apt install firebird-dev firebird3.0-server firebird3.0-examples
GRUB选项
安装过程中有如下选择项：
Continue without installing GRUB? [yes/no]
感觉有点奇怪，怎么跟grub关联的？ 选yes
提示密码
Firebird有一个名为SYSDBA的特殊用户，该用户
可以访问所有数据库。SYSDBA还可以创建新的数据库
以及用户。因此，有必要使用密码。
密码存储在/etc/firebird/3.0/SYSDBA.password中
（只能由root读取）。你可以在那里修改它（别忘了
也可以使用gsec实用程序更新安全数据库），或者
可以使用dpkg重新配置来更新两者。
如果你不输入密码，将使用随机密码（和
存储在SYSDBA.password中）。
设好密码，安装完成。
有些版本firebird的默认密码是masterkey
启动服务
service firebird3.0 start
* Starting Firebird 3.0 server... [ OK ]
在FreeBSD下安装firebird
pkg update
pkg install firebird30-client firebird30-server
FreeBSD下安装还是挺方便的，完成后的提示：
Firebird 3 was installed.
1) Before start the server ensure that the following line exists in /etc/services:
gds_db 3050/tcp #InterBase Database Remote Protocol
2) If you use inetd (Classic Server) then add the following line to /etc/inetd.conf
gds_db stream tcp nowait firebird /usr/local/sbin/firebird firebird
And finally restart inetd.
3) If you want to use change firebird modes then you must modify the ServerMode
variable into /usr/local/etc/firebird/firebird.conf file.
ServerMode="Super"
# ServerMode="SuperClassic"
# ServerMode="Classic"
4) It is STRONGLY recommended that you change the SYSDBA
password with:
# gsec -user SYSDBA -pass masterkey
GSEC> modify SYSDBA -pw newpassword
GSEC> quit
before doing anything serious with Firebird.
5) See documentation in /usr/local/share/doc/firebird/ for more information.
6) Some firebird tools were renamed for avoid conflicts with some other ports
/usr/local/bin/isql -> /usr/local/bin/isql-fb
/usr/local/bin/gstat -> /usr/local/bin/fbstat
/usr/local/bin/gsplit -> /usr/local/bin/fbsplit
6) Enjoy it ;)
总体感觉FreeBSD下比较靠谱。
