yum install -y libaio-devel libaio necurses-devel necurses readline-devel.x86_64 readline.x86_64 openssl openssl-devel

1. 安装 gcc

yum install -y centos-release-scl
yum install -y devtoolset-8-gcc.x86_64 devtoolset-8-gcc-c++.x86_64 devtoolset-8-gdb.x86_64 cmake
source /opt/rh/devtoolset-8/enable
gcc -v

2. 安装 cmake

wget https://github.com/Kitware/CMake/releases/download/v3.16.4/cmake-3.16.4-Linux-x86_64.sh
chmod +x cmake-3.16.4-Linux-x86_64.sh

./cmake-3.16.4-Linux-x86_64.sh --prefix=/usr/local
echo "export PATH=$PATH:/usr/local/cmake-3.16.4-Linux-x86_64/bin" >>/etc/profile & source /etc/profile
cmake --version

3. 下载源码包

wget https://mirrors.cloud.tencent.com/mysql/downloads/MySQL-8.0/mysql-boost-8.0.19.tar.gz
tar -xzvf MySQL-8.0/mysql-boost-8.0.19.tar.gz

4. 测试编译环境

cd /root/mysql-8.0.19
mkdir build
cd build
cmake ../ -DWITH_BOOST=../boost/

5. 编译MySQL

cd ..
rm -rf build
mkdir build
cmake ../
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql8
-DWITH_BOOST=../boost/

DEBUG 方式

cmake ../  \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql8 \
-DWITH_DEBUG=1 \
-DCMAKE_BUILD_TYPE=Debug \
-DWITH_BOOST=../boost/ 

6. 安装

make install

7. 建用户及实例目录

mkdir -p /data/mysql/mysql3306/{data,logs,tmp}
上传配置文件到/data/mysql/mysql3306/
groupadd mysql
useradd -g mysql -s /sbin/nologin -d /usr/local/mysql8 -MN mysql
chown -R mysql:mysql /usr/local/mysql8/
chown -R mysql:mysql /data/mysql/mysql3306/

8. 初始化database:

/usr/local/mysql8/bin/mysqld --defaults-file=/data/mysql/mysql3306/my3306.cnf --initialize
echo "export PATH=$PATH:/usr/local/mysql8/bin" >>/etc/profile & source /etc/profile

9. 启动MySQL Server:

/usr/local/mysql8/bin/mysqld_safe --defaults-file=/data/mysql/mysql3306/my3306.cnf &

10. 登录mysql

mysql -S /tmp/mysql3306.sock -p

11、改密码

cat /data/mysql/mysql3306/data/error.log | grep passwor
mysql -S /tmp/mysql3306.sock -p
mysql>alter user current_user() identified by 'abc123';
