好了，到这里就安装完成了，安装好以后会在桌面上有个图标，你双击打开即可。如下图：

二、Linux 客户端

注，Linux客户端安装就比较简单了，直接用yum安装一下就好！

[root@test ~]# yum install -y git

到这里git就安装完成了，下面我们查看一下版本：

[root@test ~]# git --version

git version 1.8.2.


下面我们生成公钥并复制到服务器上：

[root@test ~]# ssh-keygen -t rsa

Generating public/private rsa key pair.

Enter file in which to save the key (/root/.ssh/id_rsa):

Created directory '/root/.ssh'.

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

Your identification has been saved in /root/.ssh/id_rsa.

Your public key has been saved in /root/.ssh/id_rsa.pub.

The key fingerprint is:

48:3c:22:76:02:f1:a2:e5:27:22:cb:4f:a7:a0:98:9d root@test.com

[root@test ~]# cat .ssh/id_rsa.pub

下面我们复制id_rsa.pub里的公钥到服务器的authorized_keys文件中。

[root@git ~]# su git

下面我们clone一个仓库到本地的目录中。

[root@test ~]# cd /data/dev

[root@test dev]# git clone git@git.jjhh.com:/data/git/project.git

Cloning into 'project'...

Are you sure you want to continue connecting (yes/no)? yes

好了，到这里我们的git客户端到这里就全部安装完成了。

[home_oojah_mqtt]
name=mqtt (CentOS_CentOS-7)
type=rpm-md
baseurl=http://download.opensuse.org/repositories/home:/oojah:/mqtt/CentOS_CentOS-7/
gpgcheck=1
gpgkey=http://download.opensuse.org/repositories/home:/oojah:/mqtt/CentOS_CentOS-7/repodata/repomd.xml.key
enabled=1

第二步：开始安装
Bash代码

sudo yum search all mosquitto 
sudo yum install mosquitto mosquitto-clients libmosquitto-devel libmosquittopp-devel python-mosquitto 

第三步：配置 如果不加密码 可以不进行下面的配置
安装完成之后，所有配置文件会被放置于/etc/mosquitto/目录下，其中最重要的就是Mosquitto的配置文件，即mosquitto.conf
vim /etc/mosquitto/conf.d/myconf.conf
添加：

password_file /etc/mosquitto/passwd
allow_anonymous false

设置用户名：sudo mosquitto_passwd -c passwd st_mqtt （st_mqtt表示用户名）根据设置来进行密码设置！
然后查看一下：cat /etc/mosquitto/passwd

最后：设置自动启动
chkconfig mosquitto on
至此已经安装完成，开启你的Mqtt之旅吧！

经过研究找到了解决方法：

1、首先给用户授权，

我用的用户是root 密码123456

然后进入到mysql里面：mysql -uroot -p123456

进入之后，首选语法为:
Sql代码 ：
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

执行代码。如图：

示例: Sql代码
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;

执行完后,再
flush privileges;

如图：

刷新一下权限就可以了,不用重启。

现在你在用navicta工具连接你虚拟机的mysql已经ok了！
