Ubuntu16.04安装MySQL5.7的教程

# 安装命令
apt-get install mysql-server
# 安装过程中需要输入mysql的root密码

# 1. 下载安装包
# 我测试过程中下载的是：mysql-server_5.7.16-1ubuntu16.04_amd64.deb-bundle.tar
# 国内镜像站：http://mirrors.sohu.com/mysql/MySQL-5.7/
wget http://mirrors.sohu.com/mysql/MySQL-5.7/mysql-server_5.7.16-1ubuntu16.04_amd64.deb-bundle.tar
# 2. 解压安装包
# 解压后将出现：
#  libmysqlclient20_5.7.16-1ubuntu16.04_amd64.deb
#  mysql-common_5.7.16-1ubuntu16.04_amd64.deb      
#  mysql-community-source_5.7.16-1ubuntu16.04_amd64.deb 
#  mysql-testsuite_5.7.16-1ubuntu16.04_amd64.deb
#  libmysqlclient-dev_5.7.16-1ubuntu16.04_amd64.deb 
#  mysql-community_5.7.16-1ubuntu16.04_amd64.changes   
#  mysql-community-test_5.7.16-1ubuntu16.04_amd64.deb 
#  libmysqld-dev_5.7.16-1ubuntu16.04_amd64.deb    
#  mysql-community-client_5.7.16-1ubuntu16.04_amd64.deb 
#  mysql-server_5.7.16-1ubuntu16.04_amd64.deb
#  mysql-client_5.7.16-1ubuntu16.04_amd64.deb    
#  mysql-community-server_5.7.16-1ubuntu16.04_amd64.deb
tar -xvf ../mysql-server_5.7.16-1ubuntu16.04_amd64.deb-bundle.tar -C ./
# 3. 使用dpkg安装依赖包
dpkg -i mysql-common_5.7.16-1ubuntu16.04_amd64.deb
dpkg -i libmysqlclient20_5.7.17-1ubuntu16.04_amd64.deb 
dpkg -i libmysqlclient-dev_5.7.17-1ubuntu16.04_amd64.deb 
dpkg -i libmysqld-dev_5.7.17-1ubuntu16.04_amd64.deb 
# 上面四个包安装应该都没有什么问题，接下来安装的包将会抛出缺少依赖包的错误
# 所缺包名当时搞忘了记下来，请仔细看一下错误信息，然后使用apt-get安装一下即可
dpkg -i mysql-community-client_5.7.17-1ubuntu16.04_amd64.deb 
dpkg -i mysql-client_5.7.17-1ubuntu16.04_amd64.deb 
dpkg -i mysql-community-source_5.7.17-1ubuntu16.04_amd64.deb 
# 接下来我们需要安装mysql-community-server包了，安装之前还需要按照一个依赖包：libmecab2
apt-get install libmecab2
dpkg -i mysql-community-server_5.7.17-1ubuntu16.04_amd64.deb 
## 安装过程中需要输入mysql的root密码

sh 
# 使用mysql -u root -p登录到数据库，然后依次执行下面语句 
# xxxxxx表示root用户的密码 
use mysql; 
update user set host = '%' where user ='root'; 
grant all privileges on *.* to 'root'@'%' identified by 'xxxxxx'; 
flush privileges; 

sh 
# 进入编辑/etc/mysql/mysql.conf.d/mysqld.conf 
vi /etc/mysql/mysql.conf.d/mysqld.conf 
# 修改ip绑定 
# 源文件中为： 
bind-address 127.0.0.1 
# 将其修改为： 
bind-address 0.0.0.0 
# 覆盖保存 
esc:wq 

sh 
# 重启命令 
service mysql restart 

# 新增用户并允许远程访问只需要在user表中增加一个用户，将host设置为%即可
# 下例默认将所有权限分配给新用户，例如：
grant all privileges on *.* to 'lethew'@'%' identified by 'abcdef';
flush privileges;
