​​mysql5.7手册​​

wget https://downloads.mysql.com/archives/get/p/23/file/mysql-5.7.40.tar.gz   # 下载解压后看INSTALL文件，README文件

安装openssl到 /usr/local/openssl

wget https://www.openssl.org/source/openssl-1.1.1t.tar.gz

wget https://boostorg.jfrog.io/artifactory/main/release/1.81.0/source/boost_1_81_0.tar.gz

解压boost代码

cmake . -DWITH_SSL=/usr/local/openssl/1.1.1 -DDOWNLOAD_BOOST=1 -DWITH_BOOST=~/src

安装完成后mysqld初始化

./sql/mysqld --initialize --user=mysql --basedir=/usr/local/mysql/5.7 --datadir=/data/mysqlfiles

* progname.c

/**

编译运行:

# echo -n "/usr/local/mysql/5.7/lib" >> /etc/ld.so.conf
# /sbin/ldconfig -v
./a.out

mysql_handler=0x7ffc9ff45990
connect success!
