### 本地机器生成密钥
ssh-keygen -t rsa
[root@localhost ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa
Your public key has been saved in /root/.ssh/id_rsa.pub
The key fingerprint is:
SHA256:PeMmQH0e2HL+jxZjYJ6/8Hej+ANJ06gm+sUIhzCLNho root@localhost
The key's randomart image is:
+---[RSA 3072]----+
| |
| . o |
| o . + = o |
| . +.. Bo= . |
|E+ . o..SoOoo |
|o.. ooo+o*+ |
|. ..+o+ooo |
| . .o o++...|
| .. o==+..|
+----[SHA256]-----+
[root@localhost ~]#
进入主机A ~/.ssh/ 目录，会发现生成了一对密钥
Your identification has been saved in /home/test/.ssh/id_rsa.
Your public key has been saved in /home/test/.ssh/id_rsa.pub.
### A将公钥文件中的内容复制到 ==> 远程服务器端B
~/.ssh/id_rsa.pub
~/.ssh/authorized_keys
## 步骤如下
[root@localhost .ssh]# pwd
/root/.ssh
[root@localhost .ssh]# ll
total 12
-rw------- 1 root root 891 Jun 1 14:52 id_rsa
-rw-r--r-- 1 root root 228 Jun 1 14:52 id_rsa.pub
-rw-r--r-- 1 root root 172 Jun 1 22:28 known_hosts
[root@localhost .ssh]# vi /root/.ssh/authorized_keys
### 粘贴id_rsa.pub内的字符串到这个文件,对于OpenSSH来说，我们需要将公钥加入到~/.ssh/authorized_keys中。每个公钥一行，千万注意不要换行，否则可能不能正常工作。
### 修改文件权限
chmod 600 /root/.ssh/authorized_keys
### 修改/etc/ssh/sshd_config 文件
修改/etc/ssh/sshd_config 文件，将RSAAuthentication 和 PubkeyAuthentication 后面的值都改成yes
将PasswordAuthentication yes 修改成 PasswordAuthentication no
### 重启SSHD
/etc/init.d/sshd restart

[MySQL] 注意MySQL5.1不支持utf8mb4 Error 1115: Unknown character set: 'utf8mb4'
[ 2023/02/23 08:48 | by 刘新修 ]
2023/02/23 08:48 | by 刘新修 ]
MYSQL5.5支持utf8mb4，MYSQL5.1并不支持“utf8mb4”。
当连接数据库时 , 如果指定了utf8mb4 , 那么会出现的错误代码为：
Error 1115: Unknown character set: 'utf8mb4'
会出现utf8mb4不兼容的情况。
所以如果想使用utf8mb4存储表情emoji字符 , 请尽快升级
