前言

---

一、Mysql源码下载

Mysql官方下载位置

wget https://downloads.mysql.com/archives/get/p/23/file/mysql-boost-5.7.36.tar.gz	#Download the source code can be unpack and installation steps

二、cmake,gcc的升级

1.cmake升级

cmake官方传送门

wget https://github.com/Kitware/CMake/releases/download/v3.24.0-rc3/cmake-3.24.0-rc3-macos10.10-universal.tar.gz
tar -zxf cmake-3.24.0-rc3-macos10.10-universal.tar.gz
cd cmake-3.24.0/
./configure									#In the process of solving dependencies can be
make 

2.gcc的安装升级

1. 源码

GCC下载位置:http://ftp.gnu.org/gnu/gcc/

下载5.3版本以上即可
tar -zxf gcc-5.5.0.tar.gz
cd gcc-5.5.0/
./contrib/download_prerequisites					#Can automatically download software required dependencies

mkdir build
cd build
../configure --enable-checking=release --enable-languages=c,c++ --disable-multilib
#--enable-languages=c,c++所支持的语言
#--disable-multilibIn the process of compiling said he was "not to do extra checking
#–disable-multilib不生成编译为其他平台可执行代码的交叉编译器
make -j 4 && make install #Number of one-time compilation task does not usually exceedCPU核心数的2倍

The compilation process spent1个小时左右,It is recommended to use down the way to upgrade

2. yum源安装

yum install centos-release-scl -y
yum install devtoolset-7-gcc* -y 
scl enable devtoolset-7 bash

三、Mysql部署

1.源码编译

tar -zxf mysql-boost
mkdir build									#Create a new directory in which the source code to compile and install
cmake ../ -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \		#Specify the installation directory location
-DMYSQL_DATADIR=/data/mysql \							#Specify the data directory location
-DMYSQL_UNIX_ADDR=/data/mysql/mysql.sock \				#Soft connection position
-DWITH_INNOBASE_STORAGE_ENGINE=1 \						#使用innodb存储引擎
-DSYSCONFDIR=/etc \										#指定配置文件所在目录
-DENABLED_LOCAL_INFILE=1 \								#Open the local import
-DWITH_EXTRA_CHARSETS=all \								#支持的字符集
-DDEFAULT_CHARSET=utf8mb4 \								#Specify the default character set used by
-DDEFAULT_COLLATION=utf8_general_ci \					#指定字符集
-DWITH_BOOST=/root/mysql-8.0.21/boost/boost_1_72_0 \	#指定boos库位置
-DDOWNLOAD_BOOST=1 \									#自动下载boosLibrary has been specified, don't need to download
make -j 2 && make install

2.rpm包安装

tar -xf mysql-5.7.31-1.el7.x86_64.rpm-bundle.tar
yum install mysql-community-client-5.7.31-1.el7.x86_64.rpm mysql-community-common-5.7.31-1.el7.x86_64.rpm mysql-community-libs-5.7.31-1.el7.x86_64.rpm mysql-community-libs-compat-5.7.31-1.el7.x86_64.rpm mysql-community-server-5.7.31-1.el7.x86_64.rpm -y

3.yum源

yum install mysql -y

四、MySQL的初始化

1.启动

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
useradd -M -d /usr/local/mysql/ -s /sbin/nologin mysql
mkdir /usr/local/mysql/data
chown mysql.mysql /usr/local/mysql/data
vim .bash_profile
	PATH=$PATH:$HOME/bin:/usr/local/mysql/bin/
source ~/.bash_profile

2.初始化

vim /etc/my.cnf
[mysqld]
datadir=/usr/local/mysql								#Specify the installation directory location
socket=/usr/local/mysql/data/mysql.sock					#指定sock文件位置
datadir=/usr/local/mysql/data							#Specify the data directory location

mysqld --initialize --user=mysql						#To initialize the database specified users asmysql
