源码安装MySQL 8

发表于 更新于
emm我们的实践作业就是要修改源码然后实现Oracel的to_number()函数

下载源码

1
scp -r zyynanyou@10.166.13.45:mysql-boost-8.0.25.tar.gz ~/

当然wget也行

安装Wget
1
yum install wget

解压缩

1
tar -zxvf mysql-boost-8.0.25.tar.gz

image-20211025145043142

环境准备

1
mkdir -p ~/mysql-8.0.25/B19031707_build/package

因为上课是多人操作，所以自己建了个目录隔离

C环境

C/C++的环境要求5.8+

scl enable devtoolset-9 bash

ln -s /opt/rh/devtoolset-9/root/bin/gcc /usr/bin/gcc
ln -s /opt/rh/devtoolset-9/root/bin/g++ /usr/bin/g++

CMake

安装此版本需要cmake版本3+

wget -c https://github.com/Kitware/CMake/releases/download/v3.22.0-rc1/cmake-3.22.0-rc1.tar.gz
tar -zxvf cmake-3.22.0-rc1.tar.gz
cd cmake-3.22.0-rc1
./configure
gmake
gmake install

ln -s /usr/local/bin/cmake /usr/bin/cmake
cmake --version

安装

先查看g++和gcc的路径

源码目录下添加文件夹会有

CMake Error at CMakeLists.txt:382 (MESSAGE):
Please do not build in-source. Out-of source builds are highly
recommended: you can have multiple builds for the same source, and there is
an easy way to do cleanup, simply remove the build directory (note that
‘make clean’ or ‘make distclean’ does not work)

You can force in-source build by invoking cmake with
-DFORCE_INSOURCE_BUILD=1

遇到的问题：make -j 8内存爆了，调小一些就行

连接

1
mysql -u root -h localhost -P 33306 -p

出现错误

ERROR 2003 (HY000): Can’t connect to MySQL server on ‘10.22.224.73:33360’ (111)

需要创建一个套接字文件在tmp

干脆创建个软连接骗一下，还真行

ln -s /home/B19031707/mysql/bin/mysql.sock /tmp/mysql.sock

修改用户名和密码

p后最好不明文输入密码，如输入密码，p和密码之间不能用空格。
