①安裝依賴

     原始碼編譯安裝需要若干Linux系統環境依賴，詳細參考https://dev.mysql.com/doc/refman/5.7/en/source-installation.html。就Ubuntu16.04LTS而言，執行以下安裝命令就OK了（如果有其他缺失的依賴cmake的時候會檢測出來甚至會打印出具體的apt和yum包名額外再執行一下安裝即可）。

apt install cmake bison libncurses5-dev build-essential

②下載原始碼

     原始碼分帶boost版的和不帶boost版的。為了方便就直接下載帶boost版的。

wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-boost-5.7.18.tar.gz
tar -xzv -f mysql-boost-5.7.18.tar.gz
 

③編譯安裝

cd mysql-5.7.18/
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DWITH_BOOST=boost
make && make install

④初始配置

     新增mysql使用者組和檔案管理。

groupadd mysql
useradd -g mysql mysql
mkdir /usr/local/mysql/data
chown -R mysql /usr/local/mysql
chgrp -R mysql /usr/local/mysql
 

     初始化MySQL安裝。

/usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

     這一過程的最後一行列印輸出了root賬戶的初始密碼（真的好隨機狗眼已瞎）“ [Note] A temporary password is generated for [email protected]:(+:rGtOj8><<”。這個密碼很重要要記下來之後連線MySQL的時候要用到！

/usr/local/mysql/bin/mysql_ssl_rsa_setup --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

     自建一個簡單的配置檔案。

vim /etc/my.cnf

[client]
socket = /tmp/mysql.sock

[mysqld]
socket = /tmp/mysql.sock
basedir = /usr/local/mysql
datadir = /usr/local/mysql/data

⑤開啟服務

     設定mysqld服務。

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
update-rc.d mysqld defaults
service mysqld start

     設定mysql符號連線。

ln -s /usr/local/mysql/bin/mysql /usr/bin/mysql

     連線mysql修改密碼。

mysql -uroot -p'(+:rGtOj8><<'
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '1024';

     因為是本地自己玩，不考慮環境安全，修改一下配置檔案（[client]），設定root直接登入和外部連線。

vim /etc/my.cnf

[client]
user = root
password = 1024
port = 3306
socket = /tmp/mysql.sock
