Commonly used configuration under Linux

This article mainly gives some commonly used Linux configurations. The system version is based on CentOs6.3, for reviewing and learning by newcomers. Please correct me if I am inappropriate.

vmware tools installation

虚拟机--->安装vmware tools
将光盘内的文件VMwareTools-10.0.6-3595377.tar.gz拖到linux里
tar -xzvf  VMwareTools-10.0.6-3595377.tar.gz
cd vmwaretools
sudo ./wmware-install.pl  然后就一直回车了

遇到：问gcc回车再输入no继续回车

1. Firewall

#启动/关闭/查询防火墙状态
service iptables start/stop/status
#配置文件vim /etc/sysconfig/iptables 开启8000端口 重启防火墙
-A INPUT -m state --state NEW -m tcp -p tcp --dport 8000 -j ACCEPT
#命令行下执行，机器重启后失效
iptables -I INPUT -p tcp --dport 8000 -j ACCEPT 
#查看防火墙是否开机启动
chkconfig iptables --list
#设置防火墙开机启动/开机不启动
chkconfig iptables on/off

2. Configure the local yum source

1.挂载光盘
    mkdir /mnt/cdrom
    mount /dev/cdrom /mnt/cdrom

2.让其他yum源失效
    cd /etc/yum.repo.d
    mv CentOS-Base.repo CentOS-Base.repo.bak
    mv CentOS-Vault.repo CentOS-Vault.repo.bak
    mv CentOS-Debuginfo.repo CentOS-Debuginfo.repo.bak

3.开启光盘yum源
    vim CentOs-Media.repo
    baseurl=file:///mnt/cdrom
    enable=1

4.开机自动加载光盘
    vim /etc/fstab

3. Configure the local yum source in the cluster

1.在集群中的一台机器上（mini4）配置好本地yum源
2.在mini4上启动http服务（yum -y install httpd, service httpd start）
3.将/mnt/cdrom软链接到/var/www/html目录下
    cd /var/www/html
    ln -s /mnt/cdrom ./centos
4.在集群中的其他机器上配置yum源
    cd /etc/yum.repo.d
    mv CentOS-Base.repo CentOS-Base.repo.bak
    mv CentOS-Vault.repo CentOS-Vault.repo.bak
    mv CentOS-Debuginfo.repo CentOS-Debuginfo.repo.bak
    mv CentOS-Media.repo CentOS-Media.repo.bak
    cp CentOS-Media.repo.bak CentOS-mini4.repo
    vim CentOs-mini4.repo

5.验证设置是否成功
    yum repolist

4. SecureCRT upload and download

yum -y install lrzsz

Upload (windows to linux)

直接从window拖到linux上，选择Zmodem

Download (linux to windows download to the default location set by SecureCRT)

sz filename

5. JDK installation

1.解压
    tar -zxvf jdk-7u45-linux-x64.tar.gz -C /usr/local
2.配置环境变量
    vim /etc/profile
    export JAVA_HOME=/usr/local/jdk1.7.0_45
    export PATH=$PATH:$JAVA_HOME/bin
3.保存后加载
    source /etc/profile

6. Modify the mapping relationship between ip address and host name

vim /etc/hosts

192.168.25.13   mini1
192.168.25.14   mini2
