Debian 9.5 - postgresql cluster 9.4。这不是全新安装 - 它是一个运行良好的系统,直到我尝试重新启动服务
所有命令:/etc/init.d/postgresql start
和service postgresql start
行为systemctl start postgresql
相同:提示挂起约 10-15 秒,然后什么都没有发生 - postgres 没有运行!
这是系统日志:

所以根本没有任何迹象表明哪里出了问题。奇怪的是,系统一直运行正常,没有任何问题 - 我的应用程序刚刚崩溃,我尝试重新启动 postgres - 现在它无法再次启动。
经过几个小时的搜索,我发现奇怪的是,它可以手动启动。
我以 postgres 用户身份登录并使用以下命令:
/usr/lib/postgresql/9.4/bin/postgres -D /var/lib/postgresql/9.4/main -c config_file=/etc/postgresql/9.4/main/postgresql.conf
它运行正常 - 没有错误,没有问题。我甚至尝试添加“-d 3”以获得更详细的输出......但是没有什么异常。它运行良好 - 问题只是 init 脚本。我该如何解决这个问题 - 或者至少找出问题的根源?
答案1
我想我解决了这个问题。感谢评论者引导我找到问题。
的权限/var/log/postgresql
不知何故发生了改变。该文件夹(以及其中的日志文件)不再属于 postgres 用户。因此显然它无法再写入/打开日志。
完成后chown postgres:postgres /var/log/postgresql/ -R
,我能够通过 init-scripts 启动 postgres
