在Linux下安裝MySQL源碼需要以下步驟：

1.下載MySQL源碼

wget https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-8.0.25.tar.gz

2.安裝依賴包

sudo apt-get install build-essential cmake libncurses5-dev libncursesw5-dev libssl-dev libmysqlclient-dev libmariadbclient-dev

3.解壓源碼文件

tar -zxvf mysql-8.0.25.tar.gz
cd mysql-8.0.25

4.創(chuàng)建安裝目錄

sudo mkdir -p /usr/local/mysql
sudo chown -R $(whoami) /usr/local/mysql

5.用cmake編譯源碼

cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DSYSCONFDIR=/etc \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DMYSQL_SKIP_NAME_RESOLVE=1 \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_BOOST=/usr/local \
-DMYSQL_UNIX_ADDR=/var/run/mysqld/mysqld.sock \
-DDEFAULT_CHARSET=utf8mb4 \
-DDEFAULT_COLLATION=utf8mb4_general_ci \
-DWITH_EMBEDDED_SERVER=OFF

6.安裝MySQL

make
sudo make install

7.配置MySQL

sudo cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql.server
sudo chmod +x /etc/init.d/mysql.server
sudo update-rc.d mysql.server defaults
sudo printf '[mysqld]\nbasedir=/usr/local/mysql\ndatadir=/usr/local/mysql/data\nsocket=/var/run/mysqld/mysqld.sock' >/etc/my.cnf
sudo useradd -r mysql -s /bin/false
cd /usr/local/mysql
sudo chown -R mysql:mysql .
sudo bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
sudo bin/mysql_ssl_rsa_setup
sudo /etc/init.d/mysql.server start

8.設(shè)置MySQL密碼

sudo /usr/local/mysql/bin/mysql_secure_installation

安裝完成后，你就可以在 Linux 下愉快地使用 MySQL 了！
