文件瘦身
进入bin目录执行
[yinyx@localhost bin]$ strip *

strip:mysqld_multi: File format not recognized
strip:mysqld_safe: File format not recognized

[yinyx@localhost bin]$ pwd
/home/yinyx/mysql-8.0.31-el7-x86_64/bin
[yinyx@localhost bin]$ rm -f mysqld-debug
strip 是用来清除C程序调试信息的。
mysqld-debug是调试MySQL用的，平时用不到，并且很大，删除掉。
初始化数据库
./bin/mysqld --defaults-file=./my.cnf --initialize-insecure --basedir="./" --datadir="./data" --socket="./bin/mysql.sock" --pid-file="./bin/mysql.pid" --console

配置my.cnf
[mysqld]
# 设置3306端口
port=3306
# 设置mysql的安装目录
basedir=/usr/local/mysql
# 设置mysql数据库的数据的存放目录
datadir=/usr/local/mysql/mysqldb
# 允许最大连接数
max_connections=1000
# 允许连接失败的次数。这是为了防止有人从该主机试图攻击数据库系统
max_connect_errors=100
# 服务端使用的字符集默认为UTF8
character-set-server=utf8mb4
# 创建新表时将使用的默认存储引擎
default-storage-engine=INNODB
# 默认使用“mysql_native_password”插件认证
default_authentication_plugin=mysql_native_password
#是否对sql语句大小写敏感，1表示不敏感
lower_case_table_names = 1
#MySQL连接闲置超过一定时间后(单位：秒)将会被强行关闭
#MySQL默认的wait_timeout 值为8个小时, interactive_timeout参数需要同时配置才能生效
interactive_timeout = 1800
wait_timeout = 1800
#Metadata Lock最大时长（秒）， 一般用于控制 alter操作的最大时长sine mysql5.6
#执行 DML操作时除了增加innodb事务锁外还增加Metadata Lock，其他alter（DDL）session将阻塞
lock_wait_timeout = 3600
#内部内存临时表的最大值。
#比如大数据量的group by ,order by时可能用到临时表，
#超过了这个值将写入磁盘，系统IO压力增大
tmp_table_size = 64M
max_heap_table_size = 64M
[mysql]
# 设置mysql客户端默认字符集
default-character-set=utf8mb4
[client]
# 设置mysql客户端连接服务端时默认使用的端口
port=3306
default-character-set=utf8mb4
配置启停脚本
上传mysql的shell文件后执行：
[yinyx@localhost mysql-8.0.31-el7-x86_64-green]$ ./mysql start
Starting MySQL ... SUCCESS!
[yinyx@localhost mysql-8.0.31-el7-x86_64-green]$ netstat -lntp
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
Active Internet connections (only servers)

进入MySQL命令行，修改数据库默认设置
./bin/mysql --defaults-file=./my.cnf --socket=./data/mysql.sock -h localhost -u root -p
默认密码为空，回车直接进入MySQL命令行
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'root';
Query OK, 0 rows affected (0.00 sec)
mysql> CREATE DATABASE test;
Query OK, 1 row affected (0.01 sec)
mysql> create user 'test'@'%' identified by 'test';
Query OK, 0 rows affected (0.01 sec)
mysql> grant all on *.* to 'test'@'%';
Query OK, 0 rows affected (0.01 sec)
mysql>
创建cmd.sh
[yinyx@localhost mysql-8.0.31-el7-x86_64-green]$ cat cmd.sh
./bin/mysql --defaults-file=./my.cnf --socket=./data/mysql.sock -h localhost -u test -ptest test
[yinyx@localhost mysql-8.0.31-el7-x86_64-green]$ ./cmd.sh

停止数据库
./mysql stop
打包绿色版
tar cfz mysql-8.0.31-el7-x86_64-green.tar.gz mysql-8.0.31-el7-x86_64-green
制作轻量版
删除bin目录不常用工具，只保留
mysqld --主程序
mysqld_safe --启动shell
mysql --命令行客户端
my_print_defaults --启动使用
mysqldump --备份数据库
