Ubuntu20.04 systemd-journald.service 服务能关掉吗

49960

sudo systemctl disable systemd-journald.service
sudo systemctl disable systemd-journal-flush.service

执行了这个之后，再查看状态还是打开的

neardi

sudo systemctl stop systemd-journald.service
sudo systemctl disable systemd-journald.service

若执行过程中有依赖，全部disable并stop掉

执行了，还是没关掉

neardi

尝试以下命令按顺序执行：

neardi@LPA3588:~$ sudo systemctl disable systemd-journald-dev-log.socket
neardi@LPA3588:~$ sudo systemctl stop systemd-journald-dev-log.socket
neardi@LPA3588:~$ sudo systemctl disable systemd-journald.socket
neardi@LPA3588:~$ sudo systemctl stop systemd-journald.socket
neardi@LPA3588:~$ sudo systemctl disable systemd-journald.service
neardi@LPA3588:~$ sudo systemctl stop systemd-journald.service

执行完验证是能关闭的：

还可以通过系统层面完全禁用并防止启动 systemd-journald 相关服务，覆盖系统配置来实现：
在 /etc/systemd/system 中创建这些服务的覆写文件：

sudo systemctl edit systemd-journald.service
sudo systemctl edit systemd-journald.socket
sudo systemctl edit systemd-journald-dev-log.socket

以上三个文件都新建为：

[Service]
ExecStart=
ExecStart=/bin/true
