Linux版本: Rocky Linux release 9.5 (Blue Onyx)
1.下载
打开MySQL-Community-Server官方下载页面:https://downloads.mysql.com/archives/community/
筛选出要下载的版本，Product Version选择8.0.39，Operating System选择Source Code，OS Version选择All，然后选择最后一个自带boost的MySQL源码包All Operating Systems (Generic) (Architecture Independent), Compressed TAR Archive Includes Boost Headers (mysql-boost-8.0.39.tar.gz)，进行下载，并将下载到的源码包先放到服务器的/opt目录下。
下载链接:
-
mysql-boost-8.0.39.tar.gz
https://downloads.mysql.com/archives/get/p/23/file/mysql-boost-8.0.39.tar.gz
解压tar包，得到文件夹mysql-8.0.39，里面就是MySQL源码和一些构建信息
[root@localhost opt]# cd mysql-8.0.39/
[root@localhost mysql-8.0.39]# ll

和编译MySQl5.7一样，进入boost/文件夹下，查看boost是哪个版本，一会编译时会用到。
[root@localhost mysql-8.0.39]# cd boost/
[root@localhost boost]# ll

2.编译安装前准备
1.新添加一个用户: mysql
useradd mysql
2.安装编译所需依赖
dnf install -y make cmake gcc gcc-c++ ncurses-devel openssl-devel libtirpc
还有些不能通过yum安装的软件包要手动下载安装
yum install -y wgetwget https://dl.rockylinux.org/pub/rocky/9/devel/x86_64/os/Packages/l/libtirpc-devel-1.3.3-9.el9.x86_64.rpmwget https://dl.rockylinux.org/pub/rocky/9/AppStream/x86_64/os/Packages/r/rpcgen-1.4-9.el9.x86_64.rpmrpm -ivh libtirpc-devel-1.3.3-9.el9.x86_64.rpmrpm -ivh rpcgen-1.4-9.el9.x86_64.rpm
然后再安装MySQL8.0.39需要的gcc工具集，安装前，需要升级软件包libsemanage为高版本，同样需要下载软件包到本地，然后rpm -Uvh更新
wget https://dl.rockylinux.org/pub/rocky/9/BaseOS/x86_64/os/Packages/l/libsemanage-3.6-2.1.el9_5.x86_64.rpmrpm -Uvh libsemanage-3.6-2.1.el9_5.x86_64.rpm
然后执行安装gcc工具集命令
yum install gcc-toolset-12-gcc gcc-toolset-12-gcc-c++ gcc-toolset-12-binutils gcc-toolset-12-annobin-annocheck gcc-toolset-12-annobin-plugin-gcc
3./usr/local/下必须新建文件夹mysql
mkdir /usr/local/mysql
3.编译安装
1.在源码目录/opt/mysql-8.0.39下执行cmake命令，进行编译前的检查和配置，使用CMake配置和生成MySQL源码编译所需的构建系统文件，安装MySQL到/usr/local/mysql目录下，-DWITH_BOOST=的路径根据源码包内自带boost的版本而定，默认端口3306，数据路径/usr/local/mysql/data，字符集utf8mb4
cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DINSTALL_DATADIR=/usr/local/mysql/data \
-DMYSQL_USER=mysql \
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysqld.sock \
-DDEFAULT_CHARSET=utf8mb4 \
-DDEFAULT_COLLATION=utf8mb4_general_ci \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_EMBEDDED_SERVER=1 \
-DFORCE_INSOURCE_BUILD=1 \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DENABLED_LOCAL_INFILE=1 \
-DEXTRA_CHARSETS=all \
-DWITH_BOOST=boost/boost_1_77_0/
2.cmake命令执行成功后，执行以下make命令开始编译安装，-j 2是同时开启两个线程编译，加速编译
make -j 2 && make install
执行后，开始编译，不断输出日志，编译的过程很耗时间，需要等待很久，编译完成后，可以在/usr/local/mysql目录下看到编译好的MySQL
[root@localhost mysql-8.0.39]# cd /usr/local/mysql/
[root@localhost mysql]# ll

drwxr-xr-x. 3 root root 17 Dec 21 18:08 var
4.安装后配置
1.在/usr/local/mysql创建一个mysql配置文件，并写入字符集相关配置进去。
vi /usr/local/mysql/my.cnf
[mysqld]port = 3306character-set-server=utf8mb4
default_authentication_plugin=mysql_native_password[mysql]
default-character-set=utf8mb4
2.在/usr/local/mysql下执行命令初始化MySQL数据库
./bin/mysqld \
--defaults-file=/usr/local/mysql/my.cnf \
--user=mysql \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data \
--initialize-insecure
3.在/usr/local/mysql目录执行以下命令，将文件所有者设置为之前新建的mysql用户
chown -R mysql:mysql ./
5.启动和测试MySQL Server
在/usr/local/mysql下执行启动脚本文件启动数据库
./support-files/mysql.server start
关闭
./support-files/mysql.server stop
重启
./support-files/mysql.server restart
登录数据库测试，切换到目录/usr/local/mysql，执行./bin/mysql -uroot -p命令登录数据库，root密码默认是空
[root@localhost mysql]# ./bin/mysql -uroot -p
