linux常用的一些操作

查看当前目录下的文件：ls

进入选定的文件： cd apache-tomcat-7.0.77

查看端口是否开通：

[root@VM_213_67_centos bin]# ss -tanl

从这里可以查看出我的80 端口，22端口，8009端口都是开放的。

接下来我们来看看linux下的安装JDK的命令，先让我们看看linux下是否有JDK的环境一般都是不可能有的。

[root@VM_213_67_centos bin]# java -version-bash: java: command not found[root@VM_213_67_centos bin]# javac -bash: javac: command not found[root@VM_213_67_centos bin]# java -version-bash: java: command not found

先从oracle复制要下载的jdk的下载地址：

http://www.Oracle.com/technetwork/Java/javase/downloads/jdk-7u1-download-513651.htm

解压jdk：tar zxvf jdk-7u71-linux-x64.tar.gz

把jdk安装在对应的文件比如我这里安装的位置：

[root@VM_213_67_centos ~]# lsanaconda-ks.cfg              glibc-2.17         mysql                                      wget-logapache-tomcat-7.0.77         glibc-2.17.tar.xz  mysql-5.6.26-linux-glibc2.5-x86_64.tar.gzapache-tomcat-7.0.77.tar.gz  jdk1.8.0_131       mysql-community-release-el7-5.noarch.rpm[root@VM_213_67_centos ~]# mv jdk1.8.0_131 /usr/local/jdk[root@VM_213_67_centos ~]# cd /usr/local[root@VM_213_67_centos local]# lsbin  etc  games  include  jdk  lib  lib64  libexec  qcloud  sa  sbin  share  src[root@VM_213_67_centos local]# cd jdk[root@VM_213_67_centos jdk]# lsCOPYRIGHT  README.html                         THIRDPARTYLICENSEREADME.txt  db       javafx-src.zip  lib  releaseLICENSE    THIRDPARTYLICENSEREADME-JAVAFX.txt  bin                          include  jre             man  src.zip[root@VM_213_67_centos jdk]# ls\> ^C[root@VM_213_67_centos jdk]# vim /etc/profile

上面是移动jdk到user文件下的local下面

接下进行jdk的编译：

[root@VM_213_67_centos jdk]# vim /etc/profile

输入i加入内容如下：export JAVA_HOME=/usr/local/jdk1.7.0_71export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jarexport PATH=$JAVA_HOME/bin:$PATH

输入“：wq”表示保存并退出

加载刚设置的变量：

source /etc/profile

查看：

[root@VM_213_67_centos jdk]# java -version

ava version "1.8.0_131"Java(TM) SE Runtime Environment (build 1.8.0_131-b11)Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)[root@VM_213_67_centos jdk]# cd /usr/local/tomcat-bash: cd: /usr/local/tomcat: No such file or directory

表示jdk安装成功

接下来的其他配置我就不写了不懂得可以私密博主：

最后装mysql的全部的步骤我也张贴出来吧！我也是第一次配置好，有空再整理出来给大家看吧！大家可以看看我配置的步骤在里面找找是否有你需要的东西，没有的话也不要喷博主，想了解web项目发布到linux服务器上的具体步骤也可以私信博主我，博主非常乐意解答。
