### 2021/09/03
|
||
1. 通过阿里云申请免费SSL证书放置cert目录中。
|
||
2. 修改`conf/nginx.conf`文件，使http全部重定向至https。
|
||
|
||
### Core Dump
|
||
|
||
通过命令`ulimit -a`查看：
|
||
|
||
```
|
||
real-time non-blocking time (microseconds, -R) unlimited
|
||
core file size (blocks, -c) 0
|
||
data seg size (kbytes, -d) unlimited
|
||
scheduling priority (-e) 0
|
||
file size (blocks, -f) unlimited
|
||
pending signals (-i) 6846
|
||
max locked memory (kbytes, -l) 228312
|
||
max memory size (kbytes, -m) unlimited
|
||
open files (-n) 65535
|
||
pipe size (512 bytes, -p) 8
|
||
POSIX message queues (bytes, -q) 819200
|
||
real-time priority (-r) 0
|
||
stack size (kbytes, -s) 8192
|
||
cpu time (seconds, -t) unlimited
|
||
max user processes (-u) 6846
|
||
virtual memory (kbytes, -v) unlimited
|
||
file locks (-x) unlimited
|
||
```
|
||
|
||
core file size这一项为0，说明不生成core dump文件。
|
||
|
||
在`/etc/profile`里面加入
|
||
|
||
```
|
||
ulimit -c unlimited
|
||
sysctl -w kernel.core_pattern=core_%t_%s_%d_%e
|
||
```
|
||
|
||
查看帮助`man 5 core`。

### 微信公众号对接
|
||
|
||
1. 公众号管理网页：设置与开发→基本配置→服务器配置。
|
||
2. 由于使用的是测试公众号，因此只能够接受消息，微信服务器会将该信息发送至我们的服务器，然后我们可以对该消息进行回复，随后该连接将被关闭。
