准备工作：
首先安装这些依赖
yum install -y flex
yum install gcc gcc-c++ cmake ncurses ncurses-devel bison libaio-devel libncurses-devel libopenssl-devel zlib-devel autoconf perl per-devel openssl gcc-g77 make - y
升级make
wget https://kojipkgs.fedoraproject.org//packages/make/4.2.1/14.fc31/src/make-4.2.1-14.fc31.src.rpm
./configure --prefix=/usr
make make install
下载 cmake 3.5 以上版本：
wget https://cmake.org/files/v3.6/cmake-3.6.3.tar.gz
解压后 执行：
./bootstrap
gmake && gmake --install
升级gcc：
https://kojipkgs.fedoraproject.org//packages/gcc/7.3.1/1.fc26/src/gcc-7.3.1-1.fc26.src.rpm
进入gcc目录，安装gcc依赖库
cd gcc && ./contrib/download_prerequisites
执行命令后它会自动下载mpfr、gmp、mpc isl这4个库
编译安装 gcc
升级 openssl
wget https://www.openssl.org/source/openssl-1.1.1c.tar.gz
解压后安装：
mkdir build &&cd build
../configure
make
make install
下载mysql
wget https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-boost-8.0.16.tar.gz
编译安装：
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql
-DMYSQL_DATADIR=/usr/local/mysql/data/
-DSYSCONFDIR=etcmysql
-DWITH_INNOBASE_STORAGE_ENGINE=1
-DMYSQL_TCP_PORT=3306
-DENABLED_LOCAL_INFILE=1
-DEXTRA_CHARSETS=all
-DDEFAULT_CHARSET=utf8mb4
-DWITH_BOOST=/home/mysql-8/mysql-8.0.16/boost
-DFORCE_INSOURCE_BUILD=1
报错：
【CMake Error at /usr/local/share/cmake-3.6/Modules/CMakeTestCCompiler.cmake:61 (message):】
【cc: error trying to exec 'cc1': execvp: No such file or directory】
修改CMakeCache.txt文件中的
CMAKE_CXX_COMPILER:FILEPATH=/usr/local/bin/c++
CMAKE_C_COMPILER:FILEPATH=/usr/local/bin/gcc
报错：
【CMake Error at CMakeLists.txt:301 (MESSAGE):】
增加参数： -DFORCE_INSOURCE_BUILD=1
make
报错：
【../runtime_output_directory/uca9dump: /lib64/libstdc++.so.6: version `CXXABI_1.3.9' not found (required by ../runtime_output_directory/uca9dump)
make[2]: *** [strings/CMakeFiles/strings.dir/build.make:64: strings/uca900_zh_tbls.cc] Error 1
make[1]: *** [CMakeFiles/Makefile2:1022: strings/CMakeFiles/strings.dir/all] Error 2】
解决：
查看 /lib64/libstdc++.so.6 版本
strings /lib64/libstdc++.so.6 | grep CXXABI
CXXABI_1.3
CXXABI_1.3.1
CXXABI_1.3.2
CXXABI_1.3.3
CXXABI_1.3.4
CXXABI_1.3.5
CXXABI_1.3.6
CXXABI_1.3.7
CXXABI_TM_1
版本不符合要求 ， 由于gcc安装在/usr/bin/local 中，故执行如下操作 ：
ln -s /usr/local/lib64/libstdc++.so.6 /lib64/libstdc++.so.6
ln -s /usr/local/lib64/libstdc++.so.6 /usr/lib64/libstdc++.so.6
报错：
【/home/mysql-8/mysql-8.0.16/storage/innobase/include/os0atomic.ic:194:2: error: #error "Unsupported platform"
#error "Unsupported platform"】问题解决：
vim /home/mysql-8/mysql-8.0.16/storage/innobase/include/os0atomic.h
1 由于没有定义arm平台的宏定义，增加参数如下：
#else
#define HAVE_ATOMIC_BUILTINS
2 vim /home/mysql-8/mysql-8.0.16/storage/innobase/include/os0atomic.ic
在os0atomic.ic中，把#elif defined(IB_STRONG_MEMORY_MODEL)改为#elif defined(HAVE_ATOMIC_BUILTINS)
报错：
【/home/mysql-8/mysql-8.0.16/storage/innobase/buf/buf0buf.cc:1220:44: error: 'SYS_gettid' was not declared in this scope
setpriority(PRIO_PROCESS, (pid_t)syscall(SYS_gettid), -20);
】问题解决
vi /home/mysql-8/mysql-8.0.16/storage/innobase/buf/buf0buf.cc
将 SYS_gettid 改为 186
报错：
【/home/mysql-8/mysql-8.0.16/storage/innobase/lock/lock0lock.cc:1571:9: error: 'os_compare_and_swap_thread_id' was not declared in this scope
cas = os_compare_and_swap_thread_id(&trx->killed_by, 0, thread_id);
】问题解决：
os_compare_and_swap_thread_id() 这个函数没有声明.
在os0atomic.h头文件中的第250行左右找到os_compare_and_swap_thread_id()这个函数的实现
修改：
# ifdef HAVE_ATOMIC_BUILTINS //HAVE_IB_ATOMIC_PTHREAD_T_GCC
#if defined(HAVE_ATOMIC_BUILTINS) //defined(HAVE_GCC_SYNC_BUILTINS)
make && make install
完成安装：
