1. 阿里云服务器相关的信息

阿里云会发一个短信到手机上, 上面有服务器的公网ip, root用户的用户名和密码.

先买一个月试用一下.

[原]阿里云服务器操作实战部署C语言开发环境(vim配置,gcc) 部署J2EE网站(jdk,tomcat)
一. 配置服务器
二. 配置C语言开发环境
三. 配置J2EE运行环境
安卓程序代写

服务器还没有启用, 统计数据基本没啥用.

20G的磁盘

2. 使用SecureCRT终端连接

(1) 连接服务器

此时进入了终端, 界面比较戳 :

(2) 配置界面

选项 -> 会话选项进行如下配置 :

配置完之后的界面 :

界面看起来帅气多了.

3. 使用xftp上传文件

打开xftp之后就会弹出下面的对话框, 选择 New 按钮;

在这个界面配置连接服务器的参数, 注意要选择SFTP协议, 因为阿里云服务器默认选择没有安装FTP, 只能使用SFTP协议连接;

点击确定之后, 就会创建这个连接;

选择想要的连接, 点击connect按钮, 就可以连接到服务器上了.

root目录 :

根目录 :

上传一个文件示例 :

二. 配置C语言开发环境

1. 安装gcc

(1) 配置yum源

yum安装gcc很容易, 使用 yum -y install gcc 命令, 就可以安装gcc编译器, 但是除了一点问题:

yum命令 : 说明安装了yum

yum -y install gcc 命令安装gcc编译器 : 安装失败, 是因为没有安装yum源.

阿里云的服务器上安装了yum, 但是没有配置yum源, 这让人很郁闷, 尤其像我这种运维小白, 查资料吧, 终与搞定了;

yum源在 etc/yum.conf 文件中进行配置 :

阿里云服务器中的 yum.conf :

[main] cachedir=/var/cache/yum keepcache=0 debuglevel=2 logfile=/var/log/yum.log distroverpkg=redhat-release tolerant=1 exactarch=1 obsoletes=1 gpgcheck=1 plugins=1 exclude=*.i?86 kernel kernel-xen kernel-debug  # Note: yum-RHN-plugin doesn't honor this. metadata_expire=1h  # Default. # installonly_limit = 3  # PUT YOUR REPOS HERE OR IN separate files named file.repo # in /etc/yum.repos.d

显然里面没有配置yum源, 需要在后面加上下面的内容 :

[base] name=CentOS-5 - Base baseurl=http://ftp.sjtu.edu.cn/centos/5/os/$basearch/ gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5  [update] name=CentOS-5 - Updates baseurl=http://ftp.sjtu.edu.cn/centos/5/updates/$basearch/ gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5  [addons] name=CentOS-5 - Addons baseurl=http://ftp.sjtu.edu.cn/centos/5/addons/$basearch/ gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5  [extras] name=CentOS-5 - Extras baseurl=http://ftp.sjtu.edu.cn/centos/5/extras/$basearch/ gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5  [centosplus] name=CentOS-5 - Plus baseurl=http://ftp.sjtu.edu.cn/centos/5/centosplus/$basearch/ gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5  #contrib - packages by Centos Users [contrib] name=CentOS-5 - Contrib baseurl=http://ftp.sjtu.edu.cn/centos/5/contrib/$basearch/ gpgcheck=1 enabled=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5  [dag] name=Dag RPM Repository for RHEL5 baseurl=http://ftp.riken.jp/Linux/dag/redhat/el5/en/$basearch/dag/

将yum源追加到 etc/yum.conf 配置文件中即可.

(2) GPG keys 错误

由于yum安装了不同版本的 GPG keys, 会出现下面的错误 :

warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID e8562897

此时解决方法 : 执行 rpm --import http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5 命令即可解决该问题;

(3) 安装gcc编译器

执行 yum -y install gcc 命令, 即可成功安装gcc编译器.
