## 先编译gmp->mpfr->mpc
cd /usr/local/src/
编译: gmp-6.1.2
tar -xvf gmp-6.1.2.tar.xz
cd gmp-6.1.2
./configure --prefix=/usr/local/gmp-6.1.2
make -j $(nproc)
make install
cd ../
编译：mpfr-4.0.2
tar -xvf mpfr-4.0.2.tar.gz
cd mpfr-4.0.2
./configure --prefix=/usr/local/mpfr-4.0.2 --with-gmp=/usr/local/gmp-6.1.2
make -j $(nproc)
make install
cd ../
编译：mpc-1.1.0
tar -xvf mpc-1.1.0.tar.gz

##备份旧 gcc 可执行文件
mv /usr/bin/gcc /usr/bin/gcc.old
mv /usr/bin/g++ /usr/bin/g++.old
mv /usr/bin/c++ /usr/bin/c++.old
mv /usr/bin/cpp /usr/bin/cpp.old
mv /usr/bin/gcov /usr/bin/gcov.old
## 创建最新gcc 执行文件软链
ln -sf /usr/local/gcc-9.2.0/bin/* /usr/bin/
## 删除lib64 目录下.py 文件不然ldconfig 报错
rm -rf /usr/local/gcc-9.2.0/lib64/libstdc++.so.6.0.27-gdb.py
echo /usr/local/gcc-9.2.0/lib64 >> /etc/ld.so.conf

## 复制libstdc++.so.6.0.27 /lib64/
cp /usr/local/gcc-9.2.0/lib64/libstdc++.so.6.0.27 /lib64/
# 创建软链 libstdc++.so.6

初始化数据库
/apps/program/mysql/bin/mysqld --initialize-insecure --user=mysql
# 说明： --initialize-insecure 是初始化无需生成默认密码直接mysql 能进去不过记得一定要设置密码 --initialize 初始化设置默认密码
/apps/program/mysql/bin/mysqld --initialize --user=mysql
#启动mysql
/etc/init.d/mysqld start
在/apps/program/logs/mysqld/error.log 查找密码
[root@xxx mysqld]# cat /apps/program/logs/mysqld/error.log | grep root@localhost
2019-08-30T12:32:40.034868+08:00 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: h3zuqsQhPO&4
这个就是密码h3zuqsQhPO&4
这些密码必须修改不然任何事都不能做
修改密码：
alter user user()identified by"123456";
flush privileges;
关闭mysql
shutdown;
启动mysql
/etc/init.d/mysqld start
mysql -p
# 输入刚刚设置密码 即可登陆MySQLmysql 创建用户
mysql 8.0 不能使用GRANT ALL PRIVILEGES ON *.* TO root@'%' IDENTIFIED BY '123456'; FLUSH PRIVILEGES; 这样的方式创建账号密码
create user 'root'@'%' identified by '123456';
flush privileges;
grant all privileges on *.* to 'root'@'%';
flush privileges;
在远程使用Navicat 或者启动mysql 客户端工具进行连接
没意外的话就能正常登陆
mysql 8.0.17 源码编译安装完成
