15 tomcat
1.介绍
tomcat：网页共享服务器
apahce下的一个项目，httpd也是
端口：8080
LNTMJ：linux + nginx + tomcat + mysql + jdk
注意：LNAMP中，若要实现用户加密访问，仅需给nginx进行加密
原因：用户仅访问nginx
2.实验
7-1 （201）安装nginx（源码包 1.21.6）
[root@localhost ~]# tar -xf nginx-1.18.0.tar.gz
[root@localhost ~]# cd nginx-1.18.0/
[root@localhost nginx-1.18.0]# useradd -s /sbin/nologin nginx
[root@localhost nginx-1.18.0]# yum -y install pcre pcre-devel zlib zlib-devel
[root@localhost nginx-1.18.0]# ./configure --user=nginx --prefix=/usr/local/ngin
[root@localhost nginx-1.18.0]# make && make install
[root@localhost ~]# vim /usr/local/nginx/conf/nginx.conf #配置nginx
user nginx; #用户改为nginx
worker_processes auto; #运行模式自动
pid logs/nginx.pid; #启用pid
log_format main '$remote_addr - $remote_user [$time_local] "$request" ' #启用是指格式
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log logs/access.log main; #启用访问日志记录
location / {
root html;
index index.html index.htm;
proxy_pass http://192.168.18.202:8080; #编写完全反向代理
}
[root@localhost ~]# ln -s /usr/local/nginx/sbin/* /usr/local/sbin/ #创建软链接方便调用
[root@localhost ~]# nginx #启动nginx
[root@localhost ~]# netstat -anpt |grep nginx
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 11142/nginx: master
7-2 （202）安装tomcat（T+J）
绿色面安装版
1）上传解压，复制即安装
[root@localhost ~]# unzip tomcat.zip
[root@localhost ~]# cd tomcat/
[root@localhost tomcat]# for i in $(ls *.tar.gz)
> do
> tar -xf $i
> done
[root@localhost tomcat]# cp -r apache-tomcat-7.0.42 /usr/local/tomcat
[root@localhost tomcat]# cp -r jdk1.7.0_25 /usr/local/jdk
2）改配置文件
[root@localhost tomcat]# vim /etc/profile
[root@localhost tomcat]# tail -n5 /etc/profile
export JAVA_HOME=/usr/local/jdk
export JAVA_BIN=/usr/local/jdk/bin
export TOMCAT_HOME=/usr/local/tomcat
export PATH=$PATH:$JAVA_BIN:$TOMCAT_HOME/bin
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
[root@localhost tomcat]# source /etc/profile
3）开启tomcat
[root@localhost tomcat]# ln -s /usr/local/tomcat/bin/* /usr/local/bin/
[root@localhost tomcat]# catalina.sh start
[root@localhost tomcat]# netstat -anpt |grep 8080
tcp6 0 0 :::8080 :::* LISTEN 7384/java
导入项目
1）网页目录
[root@localhost tomcat]# cd /usr/local/tomcat/webapps/
[root@localhost webapps]# mkdir /temp
[root@localhost webapps]# mv ./* /temp/
[root@localhost webapps]# cp -r /root/tomcat/xbz.war ./
2）修改配置文件
[root@localhost webapps]# vim /usr/local/tomcat/conf/server.xml
<Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true">
<Context path="" docBase="xbz.war" debug="0" privileged="true"/>
重启tomcat、浏览器访问nginx进行测试
[root@localhost ~]# /usr/local/tomcat/bin/catalina.sh stop
[root@localhost ~]# /usr/local/tomcat/bin/catalina.sh start
3 创建多个tomcat实例
1、首先将tomcat进行停止
[root@localhost ~]# /usr/local/tomcat/bin/catalina.sh stop
2、拷贝原来的Tomcat到另外一个目录，如tomcat-2，清除logs目录
[root@localhost local]# cp -a tomcat/ tomcat-2
[root@localhost local]# rm -rf tomcat-2/logs/*
3、修改Tomcat-2中的/conf/server.xml文件，把shutdown和Connector端口修改成另外的数值，关闭端口修改为 8006，连接端口修改为8090
[root@localhost local]# vim /usr/local/tomcat-2/conf/server.xml
<Context path="" docBase="xbz.war" debug="0" privileged="true"/>
<Server port="8006" shutdown="SHUTDOWN">
<Connector port="8090" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
4、修改startup.sh和shutdown.sh文件
在第一行均加入：
export CATALINA_HOME=/usr/local/tomcat-2
[root@localhost local]# vim /usr/local/tomcat-2/bin/startup.sh
[root@localhost local]# vim /usr/local/tomcat-2/bin/shutdown.sh
5、启动tomcat
[root@localhost ~]# /usr/local/tomcat/bin/catalina.sh start
[root@localhost ~]# /usr/local/tomcat-2/bin/catalina.sh start
[root@localhost ~]# netstat -anpt |egrep "8080|8090" #查看8080和8090端口是否正常启动
tcp6 0 0 :::8080 :::* LISTEN 38560/java
tcp6 0 0 :::8090 :::* LISTEN 38579/java
tcp6 0 0 127.0.0.1:8080 127.0.0.1:34202 TIME_WAIT -
6、查看结果
可以直接将8090写入配置好的Nginx负载均衡中mjm
