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.debtar -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.debdpkg -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：libmecab2apt-get install libmecab2dpkg -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;
