tomcat 部署站点（jforum），并通过nginx代理，实现动静分离

一、环境

tomcat:
IP:192.168.1.22		Centos7.7
nginx:
IP:192.168.1.21		Centos7.7

二、基于tomcat部署jforum站点

1、yum 安装jdk11

[root@localhost ~]# yum install java-11-openjdk.x86_64 -y
[root@localhost ~]# java --version
openjdk 11.0.7 2020-04-14 LTS
OpenJDK Runtime Environment 18.9 (build 11.0.7+10-LTS)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.7+10-LTS, mixed mode, sharing)

2、安装配置tomcat

下载tomcat9.0，解压、改名至/usr/local/tomcat

[root@localhost src]# wget -c https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-9/v9.0.36/bin/apache-tomcat-9.0.36.tar.gz
[root@localhost src]# tar -zxvf apache-tomcat-9.0.36.tar.gz 
[root@localhost src]# mv apache-tomcat-9.0.36 /usr/local/tomcat

下载站点，解压至/usr/local/tomcat/webapps/jforum/ROOT/目录下

[root@localhost src]# wget -c https://jaist.dl.sourceforge.net/project/jforum2/jforum-2.5.0.war
[root@localhost src]# mkdir -p /usr/local/tomcat/webapps/jforum/ROOT
[root@localhost src]# unzip jforum-2.5.0.war -d /usr/local/tomcat/webapps/jforum/ROOT/

配置server.xml

[root@localhost src]# vim /usr/local/tomcat/conf/server.xml 
      <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
			<Context path="/" docBase="/usr/local/tomcat/webapps/jforum/ROOT" reload="true" />  增加此行，定义别名及路径，使用192.168.1.22:8080来访问，但会覆盖tomcat主页

也可以这样
<Context path="/jforum" docBase="/usr/local/tomcat/webapps/jforum/ROOT" reloadable="true" />
那么应该通过http://192.168.1.22:8080/forums，出现bbs网页，不会覆盖tomcat主页(8080)
注:这里要放在ROOT目录下，否则会报404

这里也可以新建一个host块，做虚拟主机
      <Host name="bbs.yjy.com"  appBase="/usr/local/tomcat/webapps/jforum/"
            unpackWARs="true" autoDeploy="true">
        </Host>

3、创建数据库jforum及配置权限

安装数据库mariadb
[root@localhost src]# yum install mariadb mariadb-server mariadb-devel –y 
[root@localhost src]# rpm -qa|grep mariadb
mariadb-5.5.65-1.el7.x86_64
mariadb-server-5.5.65-1.el7.x86_64
mariadb-libs-5.5.65-1.el7.x86_64
mariadb-devel-5.5.65-1.el7.x86_64
创建数据库jforum
MariaDB [(none)]> create database jforum charset utf8;
Query OK, 1 row affected (0.00 sec)
对本机授权
MariaDB [(none)]> grant all on jforum.* to "jforum"@localhost identified by "123456";
Query OK, 0 rows affected (0.00 sec)
刷新权限
MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.00 sec)

4、开始安装jforum

启动tomcat

[root@localhost ~]# /usr/local/tomcat/bin/
catalina.sh      configtest.sh    digest.sh        setclasspath.sh  startup.sh       version.sh       
ciphers.sh       daemon.sh        makebase.sh      shutdown.sh      tool-wrapper.sh  
[root@localhost jforum]# /usr/local/tomcat/bin/catalina.sh start
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.
[root@localhost ~]# netstat -tnlp

[root@localhost ~]# firewall-cmd --zone=public --add-port=8080/tcp --permanent
success
[root@localhost ~]# firewall-cmd --reload
success

三、192.168.1.21安装NGINX并代理forum,并做动静分离

yum 安装nginx

[root@localhost ~]# yum install nginx

编辑配置文件
[root@localhost ~]# vim /etc/nginx/conf.d/bbs.yjy.com.conf

server {
        listen 80;
        server_name bbs.yjy.com;
        location / {
                proxy_pass      http://192.168.1.22:8080;
        }

        location ~ .*\.(htm|html|js|css|txt|png|jpg|jpeg|doc)$ {
                root    /data/tomcat/jforum;
                expires 30d;	缓存30天
        }
        error_page 500 502 503 504 /50x.html;
}

将tomcat数据同步至nginx静态目录

[root@localhost ~]# rsync -av root@192.168.1.22:/usr/local/tomcat/webapps/jforum/ROOT/ /data/tomcat/jforum/
