因为初始化界面不太美观，可以设置配置文件，方法如下：
cd ~/.config/terminator/
sudo vim config
如果报错，Unable to open ~/.config/terminator/config ，解决方法：
打开terminator终端，然后右击终端的黑色背景，选择preference->layouts->add，关闭该窗口即可找到config文件。
修改配置文件，我的配置文件如下：
[global_config]
[keybindings]
[profiles]
[[default]]
use_system_font = False # 是否启用系统字体
login_shell = True
background_darkness = 0.92 # 背景颜色
background_type = transparent
background_image = None
cursor_color = "#3036ec" # 光标颜色
foreground_color = "#00ff00"
show_titlebar = False # 不显示标题栏，也就是 terminator 中那个默认的红色的标题栏
custom_command = tmux
font = Ubuntu Mono # 字体设置，后面的数字表示字体大小
[layouts]
[[default]]
[[[child1]]]
type = Terminal
parent = window0
[[[window0]]]
type = Window
parent = ""
[plugins]
最后的效果：
