ubuntu16.04源码安装mysql-8.0.17

进入http://mirrors.163.com/mysql/Downloads/MySQL-8.0下，查找你喜欢的mysql版本

使用wget下载

1.安装依赖

sudo apt-get install gcc g++ make cmake libssl-dev libncurses5-dev pkg-config -y

2.cmake、make、make install出错时

make clean
sudo rm CMakeCache.txt

3.编译很耗内存，至少1G，须要增长交换空间，机器好的能够忽略这一步

sudo dd if=/dev/zero of=/swapfile bs=1M count=2048
sudo mkswap /swapfile
sudo swapon /swapfile
sudo swapon -s

增长了仍是不够时

sudo swapoff -a

再次执行上面的命令

4.添加用户组、文件夹以及权限

sudo groupadd mysql
sudo useradd -g mysql mysql
sudo mkdir -p /usr/local/mysql/data
sudo chown -R mysql:mysql /usr/local/mysql

5.进入mysql源码目录再建立build目录，而后进入build目录（make的时候会产生不少文件及文件夹目录）

cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DWITH_BOOST=/home/vagrant/src/mysql-8.0.17/boost -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_SSL=system -DFORCE_INSOURCE_BUILD=1 && make && sudo make install

6.初始化mysql生成root帐号密码

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

7.把mysqld放到/etc/init.d/下，方便使用

sudo cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

sudo chmod +x /etc/init.d/mysqld

sudo vim /etc/init.d/mysqld
	basedir=/usr/local/mysql
	datadir=/usr/local/mysql/data

sudo update-rc.d mysqld defaults

sudo service mysqld start

ps -ef | grep mysqld

8.登陆mysql

export PATH=$PATH:/usr/local/mysql/bin

mysql -uroot -p

ALTER USER 'root'@'localhost' IDENTIFIED BY '新密码';

如 ALTER USER 'root'@'localhost' IDENTIFIED BY 'root';

make的时候会很是慢，耐心等待！
