初始化完数据库提示缺少server文件的处理方法

文档用途

本文档适用于解决数据库启动过程中提示缺少server文件。

详细信息

1.问题描述：
部分数据库安装包在安装后不会自动初始化数据库，需手动进行初始化数据库，初始化完成后按照提示启动数据库时会提示报错：

waiting for server to start....2020-12-23 15:07:11.690 CST [17303] FATAL:  could not load server certificate file "server.crt": No such file or directory
2020-12-23 15:07:11.690 CST [17303] LOG:  database system is shut down

2.解决方案：
将安装目录下etc目录下的server.key及server.crt文件拷贝至data目录下并将server.key赋权为0600
具体步骤（以4.5.2为例）：

2.1 拷贝server文件至data目录

[root@hgdw3 etc]# cp  /opt/HighGo4.5.2-see/etc/server.* /opt/HighGo4.5.2-see/data

2.2 对server.key赋权

[root@hgdw3 etc]# chmod 0600 /opt/HighGo4.5.2-see/data/server.key

2.3 启动数据库

[root@hgdw3 etc]# pg_ctl startwaiting for server to start....2020-12-23 16:33:22.091 CST [22309] LOG:  starting HighGo Security Enterprise Edition Database System 4.5.2 on CentOS7 x86_64,build on 20201009
