安裝Tomcat目錄概要

cd /usr/local/src
wget https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.24/bin/apache-tomcat-8.5.24.tar.gz
tar zxvf apache-tomcat-8.5.20.tar.gz
mv apache-tomcat-8.5.20 /usr/local/tomcat
/usr/local/tomcat/bin/startup.sh
ps aux|grep tomcat
netstat -lntp |grep java
三個端口8080爲提供web服務的端口，8005爲管理端口，8009端口爲第三方服務調用的端口，好比httpd和Tomcat結合時會用到

安裝Tomcat

tomcat雖然是jdk和java 的中間件，可是若是沒有了它，就不能去監聽8080端口或80端口，也沒法讓客戶端或者瀏覽器去訪問直接訪問站點，tomcat就是一個java的webserver
tomcat依賴於jdk ，因此須要先安裝jdk

切換到/ues/local/src/目錄下

[root@hf-01 ~]# cd /usr/local/src
[root@hf-01 src]#

下載tomcat的安裝包（二進制免編譯包），命令 wget https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.24/bin/apache-tomcat-8.5.24.tar.gz

[root@hf-01 src]# wget https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.24/bin/apache-tomcat-8.5.24.tar.gz

解壓包

[root@hf-01 src]# tar zxf apache-tomcat-8.5.24.tar.gz 
[root@hf-01 src]#

解壓完以後，移動到/usr/local/目錄下，並更更名字爲tomcat

mv apache-tomcat-8.5.24 /usr/local/tomcat

[root@hf-01 src]# mv apache-tomcat-8.5.24 /usr/local/tomcat
[root@hf-01 src]#

啓動tomcat，由於tomcat軟件包下載的是二進制免編譯包，不用去編譯

/usr/local/tomcat/bin/startup.sh

[root@hf-01 src]# /usr/local/tomcat/bin/startup.sh  //這樣就能把tomcat啓動
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr/local/jdk1.8
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.
[root@hf-01 src]#

這時候能夠grep查看是否有java的進程，如果有java這個進程，說明tomcat正常啓動了

[root@hf-01 src]# ps aux |grep java
root      2800  2.5  8.6 2296760 87456 pts/0   Sl   13:02   0:04 /usr/local/jdk1.8/bin/java -Djava.util.logging.config.file=/usr/local/tomcat/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djdk.tls.ephemeralDHKeySize=2048 -Djava.protocol.handler.pkgs=org.apache.catalina.webresources -Dignore.endorsed.dirs= -classpath /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar -Dcatalina.base=/usr/local/tomcat -Dcatalina.home=/usr/local/tomcat -Djava.io.tmpdir=/usr/local/tomcat/temp org.apache.catalina.startup.Bootstrap start
root      2844  0.0  0.0 112680   976 pts/0    R+   13:05   0:00 grep --color=auto java
[root@hf-01 src]#

關閉tomcat的命令爲/usr/local/romcat/bin/shutdown.sh ，tomcat不支持restart，如果更改了配置文件，須要去從新啓動，先stop，而後start

/usr/local/tomcat/bin/shutdown.sh
關閉tomcat，再來查看進程，會看到tomcat已經關閉

[root@hf-01 src]# /usr/local/tomcat/bin/shutdown.sh
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr/local/jdk1.8
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
[root@hf-01 src]# ps aux |grep java
root      2875  0.0  0.0 112680   972 pts/0    R+   13:09   0:00 grep --color=auto java
[root@hf-01 src]#

這時再啓動tomcat

[root@hf-01 src]# /usr/local/tomcat/bin/startup.sh
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr/local/jdk1.8
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.
[root@hf-01 src]#

查看tomcat的監聽端口，會看到的監聽端口爲8080端口和8009端口，還有一個8005端口

8080爲提供web服務的端口，8005爲管理端口，8009端口爲第三方服務調用的端口，好比httpd和Tomcat結合時會用到
通常使用的是8080端口

[root@hf-01 src]# netstat -lntp |grep java
tcp6       0      0 :::8080                 :::*                    LISTEN      2893/java           
tcp6       0      0 127.0.0.1:8005          :::*                    LISTEN      2893/java           
tcp6       0      0 :::8009                 :::*                    LISTEN      2893/java           
[root@hf-01 src]#

關閉防火牆

關閉firlewalld
- systemctl stop firewalld
- systemctl disable firewalld

關閉防火牆
[root@hf-01 src]# systemctl stop firewalld
[root@hf-01 src]# systemctl disable firewalld
