mysql8 安装

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=\etc\mysql\

-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

 

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：

 

【初始化数据库时 报错：

创建  /et/my.cnf

vim  /etc/my.cnf

[mysql]

default-character-set = utf8mb4

[mysqld]

初始化mysql

bin/mysqld --initialize --user=mysql

初始登录密码如高亮处

启动：

bin/mysqld_safe --user=mysql &

登录 ：

/usr/local/bin/mysql -u root -p

修改密码：
