1、通过官网下载对应的版本后，通过FTP上传至云服务器的/usr/local/src 目录
2、解压缩文件
[root@JSH-01 src]# ls
mysql-boost-8.0.12.tar.gz
[root@JSH-01 src]# tar zxvf mysql-boost-8.0.12.tar.gz
[root@JSH-01 src]# ls
mysql-8.0.12 mysql-boost-8.0.12.tar.gz3、重命名文件夹
[root@JSH-01 src]# mv mysql-8.0.12 mysql
[root@JSH-01 src]# ls
mysql mysql-boost-8.0.12.tar.gz
[root@JSH-01 src]# cd mysql
[root@JSH-01 mysql]# ls
boost config.h.cmake Doxyfile.in libbinlogevents man plugin sql testclients win
client configure.cmake doxygen_resources libbinlogstandalone mysql-test README sql-common unittest
cmake dbug extra libmysql mysys run_doxygen.cmake storage utilities
CMakeLists.txt Docs include libservices mysys_ssl scripts strings VERSION
components Doxyfile-ignored INSTALL LICENSE packaging share support-files vio4、安装cmake工具 yum install -y cmake
5、cmake构建编译环境
cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/src/mysql -DMYSQL_DATADIR=/usr/local/src/mysql/var -DSYSCONFDIR=/usr/local/src/mysql/etc -DWITH_DEBUG=0 -DWITH_INNODB_MEMCACHED=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DENABLED_PROFILING=0 -DCMAKE_C_FLAGS="-O3" -DCMAKE_CXX_FLAGS="-O3"
6、cmake报错汇总：
错误1、 CMake Warning at CMakeLists.txt:185 (MESSAGE):Could not find devtoolset gcc解决方案：yum install -y gcc
再次执行cmake编译
错误2、**-- Could NOT find Git (missing: GIT_EXECUTABLE) **解决方案：yum install -y git
错误3、-- The CXX compiler identification is unknown
CMake Error: your CXX compiler: "CMAKE_CXX_COMPILER-NOTFOUND" was not found. Please set CMAKE_CXX_COMPILER to a valid compiler path or name.解决方案：yum install -y gcc gcc-c++
再次执行cmake编译
错误4、CMake Error at cmake/boost.cmake:101 (MESSAGE):You can download it with -DDOWNLOAD_BOOST=1 -DWITH_BOOST=<directory>解决方案：编译选项中增加
-DDOWNLOAD_BOOST=1 -DWITH_BOOST=/usr/local/src/mysql
回车后，系统会自动下载并解压缩该文件
错误5、Cannot find appropriate system libraries for WITH_SSL=system.
Make sure you have specified a supported SSL version.
Valid options are :
system (use the OS openssl library),
yes (synonym for system),
</path/to/custom/openssl/installation>,
wolfssl (use wolfSSL. See extra/README-wolfssl.txt on how to set this up)错误6、CMake Error at cmake/ssl.cmake:68 (MESSAGE):Please install the appropriate openssl developer package.
解决方案5：编译选项中增加 -DWITH_SSL=system
解决方案6：yum install ncurses-devel 和 yum install openssl-devel
7、执行编译 make -j N(N为线程数，一般为服务器中CPU的个数)
查看Linux系统CPU信息：
cat /proc/cpuinfo查看Linux系统CPU物理个数：
cat /proc/cpuinfo| grep "physical id"| sort| uniq| wc -l8、cmake -j 编译过程中的错误信息
[ 56%] Building CXX object storage/innobase/CMakeFiles/innobase.dir/handler/i_s.cc.o
错误 c++: internal compiler error: Killed (program cc1plus)
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://bugzilla.redhat.com/bugzilla> for instructions.
make[2]: *** [storage/innobase/CMakeFiles/innobase.dir/handler/handler0alter.cc.o] Error 4
make[2]: *** Waiting for unfinished jobs....
make[1]: *** [storage/innobase/CMakeFiles/innobase.dir/all] Error 2
make: *** [all] Error 2
解决方案：根据错误信息提示 internal compiler error: Killed (program cc1plus) 判断为编译过程中内存耗尽, 导致了编译中断，解决办法就是增加一个交换分区:
[root@JSH-01 mysql]# dd if=/dev/zero of=/swapfile bs=1k count=2048000 //创建分区文件, 大小 2G
2048000+0 records in
2048000+0 records out
2097152000 bytes (2.1 GB) copied, 16.9483 s, 124 MB/s
[root@JSH-01 mysql]# mkswap /swapfile //生成 swap 文件系统
Setting up swapspace version 1, size = 2047996 KiB
no label, UUID=5c0b0fa8-7396-4b89-998f-29b6b269a938
[root@JSH-01 mysql]# swapon /swapfile //激活 swap 文件
swapon: /swapfile: insecure permissions 0644, 0600 suggested.
