它安装了postgresql 8.4作为(启动脚本)

/etc/init.d/postgresql

数据目录

/etc/postgresql/8.4/main/

我的问题是,有时内核决定在内存不足的情况下杀死一些Postgresql进程.我想通知内核不应该选择Postgresql被杀死.我从postgresql文档(http://www.postgresql.org/docs/9.1/static/kernel-resources.html)中读到命令行echo -17> / proc / self / oom_adj可用于避免kill.

我试图将此命令行添加到/etc/init.d/postgresql脚本,但实际上并不知道将它放在哪里.

任何指针如何去做？该方法的scipt(/etc/init.d/postgresql)是：

#!/bin/sh
set -e
