配置系统环境

系统版本：Ubuntu 20.04.2 LTS
源地址：阿里源

cat  /etc/apt/sources.list  | grep -v ^#  |grep -v ^$

#更新源

apt  update  &&  apt  upgrade

开始部署

1.0 下载源码软件包
#官网

https://downloads.mysql.com/archives/community/

#命令行直接下载

wget https://downloads.mysql.com/archives/get/p/23/file/mysql-boost-5.7.33.tar.gz
tar -xf  mysql-boost-5.7.33.tar.gz && cd mysql-5.7.33

2.0 安装编译环境

apt install -y  build-essential cmake bison libncurses5-dev libssl-dev pkg-config

#预编译环境

cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \\
-DMYSQL_DATADIR=/usr/local/mysql/data \\
-DWITH_BOOST=boost \\   #指定依赖环境
-DDEFAULT_CHARSET=utf8 \\  #指定字符集
-DDEFAULT_COLLATION=utf8_general_ci \\  #下载所有字符集
-DMYSQL_UNIX_ADDR=/tmp/mysql.sock \\    
-DFORCE_INSOURCE_BUILD=ON

#开始编译，大概20分钟编译完成

make -j2 && make install

3.0 配置用户文件属性

groupadd mysql
useradd -g mysql mysql
mkdir -p /usr/local/mysql/data
mkdir -p /usr/local/mysql/logs/
chown -R mysql:mysql /usr/local/mysql

4.0 初始化系统配置

/usr/local/mysql/bin/mysqld  \\
--initialize-insecure   \\
--user=mysql  \\
--basedir=/usr/local/mysql   \\
--datadir=/usr/local/mysql/data

#配置ssl

/usr/local/mysql/bin/mysql_ssl_rsa_setup  \\
--user=mysql \\
--basedir=/usr/local/mysql \\
--datadir=/usr/local/mysql/data

#主配置文件

cat  /etc/my.cnf 
[client]
default-character-set=utf8
socket=/tmp/mysql.sock

[mysqld]
basedir=/usr/local/mysql
port=3306
datadir=/usr/local/mysql/data/
socket=/tmp/mysql.sock
log_error=/usr/local/mysql/logs/error.log
max_connections=2000
default-storage-engine=INNODB
max_allowed_packet=16M
innodb_buffer_pool_size=128M
explicit_defaults_for_timestamp=true

5.0 配置启动服务

cp /usr/local/mysql/support-files/mysql.server  /etc/init.d/mysqld
cp /usr/local/mysql/support-files/mysql.server  /usr/lib/systemd/system/
chmod +x /etc/init.d/mysqld
update-rc.d mysqld defaults

#配置环境变量

echo -e '# MySQL PATH\\nexport PATH=/usr/local/mysql/bin:$PATH\\n' >> /etc/profile
source /etc/profile

#启动服务

systemctl restart mysqld
systemctl enable  mysqld

#配置密码

mysql  -e "alter user 'root'@'localhost' identified by 'root';"

远程登录配置
mysql>GRANT ALL PRIVILEGES ON . TO ‘root’@’%’ IDENTIFIED BY ‘123456’ WITH GRANT OPTION;
mysql>flush privileges;

#验证数据库

mysql  -uroot -proot  -e "show databases;"

至此 20.4系统源码安装mysql5.7数据库完成
