博客总结 : 设置SecureCRT显示行数 : 会话选项 -> 终端 -> 仿真 -> 回滚(回滚缓冲区) 设置一个NNNN值.

在公司呆久了, 感觉全身都生锈了, 突然心血来潮, 准备自己用java写一个网站.

选来选去, 最终感觉阿里云的服务器性价比蛮高的, 买了一个最便宜的配置用来学习用.

在家里配置了一下, 到了公司又不会配置了, 怕忘了写篇博客记录下来, 一通配置下来, 发现自己有运维工程师的潜质.

一. 配置服务器

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.

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 :

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.
