The official version 8.0.11 of MySQL 8.0 has been released. Officially, MySQL 8 is 2 times faster than MySQL 5.7, and it also brings a lot of improvements and faster performance!
Note: Upgrading from MySQL 5.7 to MySQL 8.0 is only supported using in-place upgrades, and downgrading from MySQL 8.0 to MySQL 5.7 is not supported
(or downgrade from a MySQL 8.0 version to any earlier MySQL 8.0 version). The only supported alternative is to back up your data before upgrading.
Operating system description: CentOS 6.4
Database version: MySQL 8.0.0
1. Environmental preparation
yum install ncurses-devel -y
yum install libaio -y
yum install glibc-devel.i686 glibc-devel -y
yum install gcc gcc-c++ -y
In addition, MySQL8.0 needs to use gcc version 4.8 or above, and centos 6.4 can only be installed to 4.4.7 through yum, so you need to manually install a higher version of gcc before installing mysql8.0, I use gcc-8.8 here. 2 for example:
wget ftp://ftp.gnu.org/gnu/gcc/gcc-4.8.2/gcc-4.8.2.tar.gz
tar xf gcc-4.8.2.tar.gz
cd gcc-4.8.2
# Download the dependencies required for compilation: ./contrib/download_prerequisites
./configure --prefix=/usr/local/gcc-4.8.2/ --enable-bootstrap --enable-threads=posix --enable-languages=c,c++,objc,obj-c++
make &&make install
Note: make will take a long time.
After installation, you also need to replace the original gcc environment with the new version of gcc, otherwise mysql will still use the original gcc during installation:
mv /usr/bin/gcc /usr/bin/gcc447
mv /usr/bin/g++ /usr/bin/g++447
mv /usr/bin/c++ /usr/bin/c++447
mv /usr/bin/cc /usr/bin/cc447
ln -s /usr/local/gcc-4.8.2/bin/gcc /usr/bin/gcc
ln -s /usr/local/gcc-4.8.2/bin/g++ /usr/bin/g++
ln -s /usr/local/gcc-4.8.2/bin/c++ /usr/bin/c++
ln -s /usr/local/gcc-4.8.2/bin/gcc /usr/bin/cc
mv /usr/lib64/libstdc++.so.6 /usr/lib64/libstdc++.so.6.bak
ln -s /usr/local/gcc-4.8.2/lib64/libstdc++.so.6.0.18 /usr/lib64/libstdc++.so.6
Solve the following problems:
Next, install the boost library:
tar xf boost_1_60_0.tar.bz2\?r\=\&ts\=1479114685\&use_mirror\=ncu
cd boost_1_60_0
./bootstrap.sh
./b2 stage threading=multi link=shared
./b2 install threading=multi link=shared
2. Install mysql8.0

wget -c http://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-boost-8.0.0-dmr.tar.gz
