mysql8 源码安装的坑-放弃了

参考文档：以下文档提出了需要一些gcc，cmake等版本的需求 
https://mysql.net.cn/doc/refman/8.0/en/source-installation-prerequisites.html
 

-- 错误 
1  
CMake Error: The source directory "/home/mysql/mysql-8.0.34-linux-glibc2.17-x86_64" does not appear to contain CMakeLists.txt.

CMake Error: The source directory does not appear to contain CMakeLists.txt.

下载了错误的包 mysql-8.0.34-linux-glibc2.17-x86_64.tar.gz
这种包 ，时已经编译好的，直接mysqld --initialize 就行了。 不用再次编译 

实际应该下载的包 
mysql-8.0.34.tar.gz

2 需要cmaker 3 

[root@redhat762100 mysql-8.0.34]# cmake \
> -DCMAKE_INSTALL_PREFIX=/mysql/my3309 \
> -DINSTALL_DATADIR=/mysql/my3309/data  \
> -DMYSQL_UNIX_ADDR=/mysql/my3309/run/mysql.sock \
> -DMYSQL_TCP_PORT=3309

3 提示找不到openssl ，需要下载安装openssl

  configure CMake with -DCMAKE_USE_OPENSSL=OFF to build without OpenSSL.

4  继续安装 ，提示需要这些包   yum install devtoolset-11-gcc devtoolset-11-gcc-c++ devtoolset-11-binutils

CMake Warning:
  No source or binary directory provided.  Both will be assumed to be the
  same as the current working directory, but note that this warning will
  become a fatal error in future CMake releases.

5 之前编译安装cmake的时候，没有./bootstrap，重新编译安装cmake 。而不是直接./configure   ,make  make install .
./bootstrap --prefix=/home/mysql/cmake/cmake   

6 发现错误是gcc版本问题 ，需要gcc7.1 

CMake Warning:
  No source or binary directory provided.  Both will be assumed to be the
  same as the current working directory, but note that this warning will
  become a fatal error in future CMake releases.

7 安装gcc，编译需要好几个小时，而且占用空间很大。磁盘空间撑爆了，放弃。

查看redhat8上，gcc是8.5 .但仍需要很多包，放弃编译安装了。
