Tomcat（二）：Nginx反向代理实现Tomcat动静分离
实验拓扑：
实验环境：
OS：CentOS-6.7-x86_64
Nginx：
IP：192.168.1.4
Tomcat：
IP：192.168.1.5
实验流程：
Tomcat：
先安装Jvm：openjdk：
[root@node1 ~]# yum install java-1.7.0-openjdk
[root@node1 ~]# java -version
java version "1.7.0_79"
OpenJDK Runtime Environment (rhel-2.5.5.4.el6-x86_64 u79-b14)
OpenJDK 64-Bit Server VM (build 24.79-b02, mixed mode)
安装tomcat：
[root@node1 ~]# tar xf apache-tomcat-7.0.65.tar.gz -C /usr/local/
[root@node1 ~]# cd /usr/local/
[root@node1 local]# ln -sv apache-tomcat-7.0.65 tomcat
"tomcat" -> "apache-tomcat-7.0.65"
[root@node1 ~]# vim /etc/profile.d/tomcat.sh
export CATALINA_HOME=/usr/local/tomcat
export PATH=$CATALINA_HOME/bin:$PATH
[root@node1 ~]# source /etc/profile.d/tomcat.sh
提供脚本：
[root@node1 ~]# cat /etc/rc.d/init.d/tomcat
#!/bin/sh
# Tomcat init script for Linux.
#
# chkconfig: 2345 96 14
# description: The Apache Tomcat servlet/JSP container.
# JAVA_OPTS='-Xms64m -Xmx128m'
JAVA_HOME=/usr/lib/jvm/jre
CATALINA_HOME=/usr/local/tomcat
export JAVA_HOME CATALINA_HOME
case $1 in
start)
exec $CATALINA_HOME/bin/catalina.sh start ;;
stop)
exec $CATALINA_HOME/bin/catalina.sh stop;;
restart)
$CATALINA_HOME/bin/catalina.sh stop
sleep 2
exec $CATALINA_HOME/bin/catalina.sh start ;;
*)
echo "Usage: `basename $0` {start|stop|restart}"
exit 1
;;
esac
[root@node1 ~]# chmod +x /etc/rc.d/init.d/tomcat
[root@node1 ~]# chkconfig tomcat --add
定义管理页面用户名及密码：
[root@node1 ~]# cd /usr/local/tomcat/conf
[root@node1 conf]# vim tomcat-users.xml
<role rolename="manager-gui"/>
<role rolename="admin-gui"/>
<user username="tomcat" password="tomcat" roles="manager-gui,admin-gui"/>
[root@node1 conf]# service tomcat start
[root@node1 conf]# chkconfig tomcat on
访问测试：
部署站点文件：
[root@node1 ~]# mkdir -p /tomcat/webapps
[root@node1 ~]# unzip JspRun\!_6.0.0_GBK.zip
[root@node1 ~]# mv upload /tomcat/webapps/jsprun
[root@node1 ~]# cd /tomcat/webapps
[root@node1 webapps]# chmod -R 777 jsprun
[root@node1 webapps]# cd jsprun
[root@node1 jsprun]# vim config.properties
dbhost = 192.168.1.5
dbport=3306
dbuser = jruser
dbpw = jrpass
dbname = jrdb
定义虚拟主机，并重启tomcat：
[root@node0 ~]# cd /usr/local/tomcat
[root@node0 tomcat]# vim conf/server.xml
<Engine name="Catalina" defaultHost="node1.chencer.org">
<Host name="node1.chencer.org" appBase="/tomcat/webapps" unpackWARs="true" autoDeploy="true">
<Context path="/bbs" docBase="jsprun" />
</Host>
[root@node1 ~]# service tomcat restart
安装并启动mysql：
[root@node0 mysql-5.5-rpm]# yum install MySQL-shared-compat-5.5.48-1.el6.x86_64.rpm MySQL-client-5.5.48-1.el6.x86_64.rpm MySQL-server-5.5.48-1.el6.x86_64.rpm
[root@node0 ~]# service mysql start
[root@node0 ~]# chkconfig mysql on
创建数据库，并赋予权限：
[root@node0 ~]# mysql
mysql> create database jrdb;
Query OK, 1 row affected (0.00 sec)
mysql> grant all on jrdb.* to 'jruser'@'192.168.1.5' identified by 'jrpass';
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
安装站点，并访问测试：
Nginx：
安装并配置Nginx：
[root@node0 ~]# yum install nginx
动态页面重定向至tomcat：
[root@node0 ~]# cd /etc/nginx/conf.d/
[root@node0 conf.d]# vim default.conf
server {
listen 80;
server_name node0.chencer.org;
index index.jsp;
location ~* \.(jsp|do)$ {
proxy_pass http://192.168.1.5:8080;
}
}
[root@node0 conf.d]# service nginx start
[root@node0 conf.d]# chkconfig nginx on
访问测试：
部署站点静态文件：
[root@node0 ~]# mkdir -p /web/jsprun
[root@node0 ~]# scp -r node1:/tomcat/webapps/jsprun/* /web/jsprun/
编辑配置文件：
[root@node0 conf.d]# vim default.conf
server {
listen 8080;
server_name 192.168.1.4;
index index.jsp;
location / {
root /web/jsprun;
index index.html;
}
}
server {
listen 80;
server_name node0.chencer.org;
index index.jsp;
location / {
proxy_pass http://192.168.1.5:8080;
}
location ~\.(html|htm|xml|gif|jpg|jpeg|ico|swf)$ {
proxy_pass http://192.168.1.4:8080;
}
location ~* \.(jsp|do)$ {
proxy_pass http://192.168.1.5:8080;
}
}
[root@node0 ~]# service nginx restart
