postgresql无法正常启动的原因追查

Posted 2023-04-09

参考技术A 仔细分析，无非几个原因：

1、log目录的权限问题，比如log文件指定的目录postgres用户无权写入，因此没有产生任何log文件。检查了/var/lib/postgresql/11/main的目录，没有发现问题。
2、配置文件的权限问题，检查了/etc/postgresql/11/main目录，也没有发现任何问题，postgres用户是有权限读取配置文件的。

3、配置文件有错误导致无法正常启动postgresql。排除了上面的两个原因，这个应该是最大的原因了。但是，错误在哪里呢？没有给出提示啊！

 尝试了service postgresql start, pg_ctrcluster, pg_ctl均无法给出任何提示，后来才想明白，这几个都是对postmaster的脚本封装啊，也许这些封装忽略了什么重要的信息！应该直接运行postmaster才能得到直接的出错提示的！果然，执行/usr/lib/postgresql/11/bin/下的postmaster给出了提示，执行语句：

 看到这里立刻明白了：我将postgresql.conf中的lc_messages改为了 en_US.UTF-8，可是没有产生en_US.UTF-8的locale文件啊！于是修改/etc/locales.gen文件添加en_US.UTF-8，执行locales.gen，再次启动postgresql，成功！

tomcat无法正常启动的一个原因

 简要报错信息：

java.lang.IllegalArgumentException: Document base E:\\apache-tomcat-7.0.65\\webapps\\springmvc01 does not exist or is not a readable directory

 如果遇到这种莫名其妙的问题，根据报错信息可以看到应该是当前的tomcat某个配置文件里有springmvc01这个工程项目的信息，我们一个一个地来排查，发现是

E:\\tomcat\\apache-tomcat-7.0.65_nm\\conf\\server.xml中多了

这行配置信息，我们只要把这段信息删除，然后重启tomcat就能够重新启动。
