Install jdk1.7, tomcat, and nginx in contos

　JDK installation in centos

　　1. First download the JDK installation package online, and then put the installation package under the usr/local/Java directory (where it is put, I am used to it)

2. Open the terminal
1> Cd/usr/local/Java (locate the folder/usr/local/Java)

2> tar zxvf jdk-7u51-linux-x64.tar.gz (decompress to the current directory)

3> Add the environment variable at the end of the/etc/profile file (configure the JDK environment variable)

Export java_home =/usr/Java/jdk1.7.0 _ 67
Export Path = $ path: $ java_home/bin
Export classpath =.: $ java_home/lib/dt. jar: $ java_home/lib/tools. Jar

4> after the modification is complete, log on to logout again or # source/etc/profile to make the file take effect immediately.

5> test Java-version (query JDK version)

　　Tomcat installation in centos

　　1. First download the tomcat installation package online, and then put the installation package under the usr/local/Java directory.

2. Open the terminal
1> Cd/usr/local/Java (locate the folder/usr/local/Java)

2> tar zxvf apache-tomcat-7.0.47.tar.gz (decompress to the current directory)

3> modify the configuration file and add the Java environment variable information. In/usr/local/Apache-Tomcat-7.0.47/bin, add the following information to the file header:

Exportjava_home =/usr/local // Java/jdk1.7.0 _ 67
Exportclasspath =.: $ classpath: $ java_home/lib: $ java_home/JRE/lib
Exportpath = $ path: $ java_home/bin: $ java_home/JRE/bin

4> start Tomcat/usr/local/Apache-Tomcat-7.0.47/bin/startup. Sh.

5> test Java-version (query JDK version)

6> test tomcat. Open the browser and access http: // 127.0.0.1: 8080. The Tomcat startup welcome page is displayed, proving that the tomcat configuration is correct.
