tar xf boost_1_59_0.tar.gz && tar xf mysql-boost-5.7.20.tar.gz

cd mysql-5.7.20

groupadd mysql

useradd mysql -s /bin/nologin -M -g mysql

mkdir -p /usr/local/mysql-5.7.20 /usr/local/mysql-5.7.20/data /usr/local/mysql-5.7.20/mysql.sock

编译安装

make -j `grep processor /proc/cpuinfo | wc -l`

make install

添加mysql的环境变量

echo -e '\n\nexport PATH=/usr/local/mysql/bin:$PATH\n' >> /etc/profile && source /etc/profile

初始化数据库

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

启动数据库

systemctl start mysqld

systemctl status mysqld

查看MySQL服务进程和端口

ps -ef | grep mysql

设置数据库root用户密码

mysql_secure_installation

常用操作

将MySQL数据库的动态链接库共享至系统链接库

一般MySQL数据库还会被类似于PHP等服务调用，所以我们需要将MySQL编译后的lib库文件添加至当前Linux主机链接库 /etc/ld.so.conf.d/

下，这样MySQL服务就可以被其它服务调用了。

ldconfig |grep mysql

echo "/usr/local/mysql/lib" > /etc/ld.so.conf.d/mysql.conf

ldconfig

ldconfig -v |grep mysql

进入数据库

mysql -uroot -p

show databases;

quit
