源码安装MySQL-8.0.16

部署MySQL

准备源码包可到官网下载

mysql源码包官网下载路径

[[email protected] ~]# https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-8.0.16-linux-glibc2.12-x86_64.tar.xz

1.解包

[[email protected] ~]# tar -xf mysql-8.0.16-linux-glibc2.12-x86_64.tar.xz

MySQL依赖于libaio 库。如果未在本地安装此库，则数据目录初始化和后续服务器启动步骤将失败。如有必要，请使用适当的包管理器进行安装。例如，在基于Yum的系统上

[[email protected] ~]# yum -y install libaio

2.把目录移到/usr/local/下并命名mysql

[[email protected] ~]# mv mysql-8.0.16-linux-glibc2.12-x86_64 /usr/local/mysql

3.创建管理用户

[[email protected] ~]# useradd -s /sbin/nologin mysql

[[email protected] ~]# chown -R mysql:mysql /usr/local/mysql

4.写配置文件/etc/my.cnf

如果有/etc/my.cnf 或/etc/mysql目录，并删除它们。小编把它们移到root下

[[email protected] ~]# mv /etc/my.cnf /root/

[[email protected] ~]# mv /etc/mysql /root

创建文件并进入

[[email protected] mysql]# vim /etc/my.cnf

[mysqld]
datadir=/var/lib/mysql
basedir=/usr/local/mysql
socket=/tmp/mysql.sock
log-error=/var/lib/mysql/mysqld.log
pid-file=/var/lib/mysql/mysqld.pid
port=3306

           

1. 初始化数据库

   [[email protected] ~ ]# cd /usr/local/mysql

   [[email protected] mysql]# bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/var/lib/mysql

6.让mysqld进程可以使用systemctl 控制

[[email protected] ~]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

[[email protected] ~]# chkconfig --add mysqld

[[email protected] ~]# chkconfig mysqld on

7.检测是否有进程（查看是否有进程号3306）

[[email protected] ~]# systemctl start mysqld

[[email protected] ~]# netstat -nutlp | grep mysql

tcp6 0 0 :::33060 ::? LISTEN 2581/

mysqld

tcp6 0 0 :::

3306

::? LISTEN 2581/

mysqld

原谅我的懒惰，不想配图

8.把/usr/local/mysql/bin下得文件变成快速执行的，不然每次打源路经，麻烦

[[email protected] ~]# PATH=$PATH:/usr/local/mysql/bin/
[[email protected] ~]# echo PATH=$PATH:/usr/local/mysql/bin/ >> /etc/profile
           

9.登陆测试

[[email protected] mysql]# grep password /var/lib/mysql/mysqld.log

2019-05-19T10:49:37.215020Z 5 [Note] [MY-010454] [Server] A temporary password is generated for [email protected]:

Sd(Tjxodg7Vr

第一次登陆它会生成一个初始密码。需要记好，可以在

/var/lib/mysql/mysqld.log

中找到

[[email protected] ~]# mysql -uroot -p'Sd(Tjxodg7Vr' 
  mysql> alter user  [email protected]'localhost' identified by "123456";
           

进去后需要把密码改了，一是方便，二是不改密码无法进行使用SQL命令
