tomcat是Apache基金會的Jakarta項目中的一個核心項目,由Apache、sun與其餘公司及我的共同開發維護,是一個web服務中間件,真正起做用的解析java腳本的是jdk(java develoment kit):java的核心,它包含了jre、java工具、java基礎庫。php
主流的jdk由sun發佈,IBM公司也有發佈jdk,Centos上yum安裝的是openjdk。html
在官網下載tar.gz包,再傳到linux系統裏,不用wget。java
http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html // 下載jdk-8u171-linux-x64.tar.gz。 //使用rz命令,從Windows傳到linux系統裏,存放到/usr/local/src目錄下。
解壓jdk:mysql
[root@nginx src]# tar xzvf jdk-8u171-linux-x64.tar.gz ##省略部分過程 jdk1.8.0_171/jre/bin/unpack200 jdk1.8.0_171/jre/plugin/ jdk1.8.0_171/jre/plugin/desktop/ jdk1.8.0_171/jre/plugin/desktop/sun_java.png jdk1.8.0_171/jre/plugin/desktop/sun_java.desktop jdk1.8.0_171/jre/README jdk1.8.0_171/jre/COPYRIGHT
移動單獨的目錄下,並更名:linux
[root@nginx src]# mv jdk1.8.0_171 /usr/local/jdk1.8 [root@nginx src]# cd .. [root@nginx local]# ls bin etc games include jdk1.8 lib lib64 libexec mysql nginx php-fpm sbin share src [root@nginx local]# cd jdk1.8/ [root@nginx jdk1.8]# ls bin db javafx-src.zip lib man release THIRDPARTYLICENSEREADME-JAVAFX.txt COPYRIGHT include jre LICENSE README.html src.zip THIRDPARTYLICENSEREADME.txt
修改環境變量:/etc/profile,增長下面幾行nginx
[root@nginx jdk1.8]# vim /etc/profile JAVA_HOME=/usr/local/jdk1.8/ JAVA_BIN=/usr/local/jdk1.8/bin JRE_HOME=/usr/local/jdk1.8/jre PATH=$PATH:/usr/local/jdk1.8/bin:/usr/local/jdk1.8/jre/bin CLASSPATH=/usr/local/jdk1.8/jre/lib:/usr/local/jdk1.8/lib:/usr/local/jdk1.8/jre/lib/charsets.jar [root@nginx jdk1.8]# source /etc/profile //從新加載profile
驗證是否安裝成功:顯示版本號,表明安裝成功web
[root@nginx jdk1.8]# java -version java version "1.8.0_171" Java(TM) SE Runtime Environment (build 1.8.0_171-b11) Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)
若是顯示的版本號是1.7,與你安裝的1.8版本不符,查看是否yum安裝過openjdksql
[root@nginx jdk1.8]# rpm -qa|grep openjdk //若是有,就卸載掉,可是在生成環境中,別亂下載,可能有服務在使用openjdk,能夠升級openjdk到1.8
下載tomcat:apache
[root@nginx src]# wget http://mirror.bit.edu.cn/apache/tomcat/tomcat-8/v8.5.31/bin/apache-tomcat-8.5.31.tar.gz --2018-06-26 22:48:17-- http://mirror.bit.edu.cn/apache/tomcat/tomcat-8/v8.5.31/bin/apache-tomcat-8.5.31.tar.gz 正在解析主機 mirror.bit.edu.cn (mirror.bit.edu.cn)... 202.204.80.77, 2001:da8:204:2001:250:56ff:fea1:22 正在鏈接 mirror.bit.edu.cn (mirror.bit.edu.cn)|202.204.80.77|:80... 已鏈接。 已發出 HTTP 請求,正在等待迴應... 200 OK 長度:9552281 (9.1M) [application/octet-stream] 正在保存至: 「apache-tomcat-8.5.31.tar.gz」 100%[====================================================================================================================>] 9,552,281 419KB/s 用時 26s 2018-06-26 22:48:47 (363 KB/s) - 已保存 「apache-tomcat-8.5.31.tar.gz」 [9552281/9552281]) [root@nginx src]# ls apache-tomcat-8.5.31.tar.gz mysql-5.6.36-linux-glibc2.5-x86_64.tar.gz nginx-1.14.0 php-5.6.32 jdk-8u171-linux-x64.tar.gz mysql-test-5.7.18-linux-glibc2.5-x86_64.tar.gz nginx-1.14.0.tar.gz php-5.6.32.tar.bz2
解壓並移動更名:bootstrap
[root@nginx src]# tar xzvf apache-tomcat-8.5.31.tar.gz apache-tomcat-8.5.31/conf/ apache-tomcat-8.5.31/conf/catalina.policy apache-tomcat-8.5.31/conf/catalina.properties apache-tomcat-8.5.31/conf/context.xml apache-tomcat-8.5.31/conf/jaspic-providers.xml apache-tomcat-8.5.31/conf/jaspic-providers.xsd [root@nginx src]# mv apache-tomcat-8.5.31 /usr/local/tomcat [root@nginx src]# cd ..

由於是二進制包,能夠直接運行:啓動腳本starup.sh

若是啓動後沒有進程,要先shutdown.sh,再從新startup.sh。由於tomcat沒有restart命令。
查看監聽端口:8080web服務端口、8009第三方服務調用的端口,如httpd和tomcat結合用、8005管理端口,8005起來纔可以使用tomcat
