一步一步教你tomcat优化和发布动态网站

Tomcat性能优化

一、安装Centos01上安装tomcat发布动态网站jpress使用www.Benet.com访问，配置虚拟机主机通过www.benet.com和www.accp.com访问不同的虚拟主机

1）上传tomcat文件包

[root@centos01 ~]# rz
[root@centos01 ~]# ls
anaconda-ks.cfg              公共  图片  音乐
apache-tomcat-8.5.50.tar.gz  模板  文档  桌面
initial-setup-ks.cfg         视频  下载

2）解压移动tomcat

[root@centos01 ~]# tar zxf ./apache-tomcat-8.5.50.tar.gz -C /usr/src/
[root@centos01 ~]# mv /usr/src/apache-tomcat-8.5.50/ /usr/local/tomcat

3）启动tomcat监听进程

[root@centos01 ~]#/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
Using CLASSPATH:      
/usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.
[root@centos01 ~]# netstat -anptu | grep java
tcp6      
0      0 :::8080                 :::*                    LISTEN      1238/java           
tcp6      
0      0 127.0.0.1:8005          :::*                    LISTEN      1238/java           
tcp6      
0      0 :::8009                 :::*                    LISTEN      1238/java

4）客户端验证

5）安装动态网站

[root@centos01 ~]#/usr/local/tomcat/bin/shutdown.sh
[root@centos01 ~]# cd /usr/local/tomcat/webapps/
[root@centos01 webapps]# ls
docs     
host-manager  jpress.war  ROOT
examples 
jpress        manager

6）安装jpress数据库

[root@centos01 webapps]# mount /dev/cdrom /mnt/
mount: /dev/sr0 写保护，将以只读方式挂载
[root@centos01 webapps]# rm -rf /etc/yum.repos.d/CentOS-*
[root@centos01 webapps]# yum -y install mariadb mariadb-server

7）启动服务设置开机自动启动

[root@centos01 ~]# systemctl start mariadb
[root@centos01 ~]# systemctl enable mariadb

8）设置用户和密码

[root@centos01 ~]# mysqladmin -uroot password
[root@centos01 ~]# mysql -uroot -ppwd@123

9）创建数据库用户访问

MariaDB [(none)]> create database jpress charset utf8;

10）授权用户访问

MariaDB [(none)]> grant all on jpress.* to 'bbs'@'localhost' identified by 'pwd@123';

11）创建数据库

12）登录进去查看动态网站

二、Centos02安装DNS域名解析www.benet.com www.accp.com www.bdqn.com访问网站

1、安装DNS

1）挂载光盘安装DNS

[root@centos02 ~]# mount /dev/cdrom /mnt/
mount: /dev/sr0 写保护，将以只读方式挂载
[root@centos02 ~]# rpm -ivh
/mnt/Packages/bind-9.9.4-50.el7.x86_64.rpm
[root@centos02 ~]# rpm -ivh
/mnt/Packages/bind-chroot-9.9.4-50.el7.x86_64.rpm

2）修改DNS服务主配置文件

[root@centos02 ~]# vim /etc/named.conf
options {
        listen-on port 53 { any; };     
directory      "/var/named";
};
zone "accp.com" IN {       
type master;      
file "/var/named/accp.com.zone";
};
zone "bdqn.com" IN {      
type master;      
file "/var/named/bdqn.com.zone";
};
zone "benet.com" IN {      
type master;      
file "/var/named/benet.com.zone";
};
3）修改DNS区域配置文件
[root@centos02 ~]# vim /var/named/benet.com.zone
$TTL            86400
@               SOA             benet.com.      root.benet.com.
(
                2023031415
                1H
                15M
                1W
                1D
)
@               NS              centos02.benet.com.
centos02        A               192.168.100.20
www             A               192.168.100.10
[root@centos02 ~]# vim
/var/named/accp.com.zone
$TTL            86400
@               SOA             accp.com.      root.accp.com.
(
                2023031415
                1H
                15M
                1W
                1D
)
@               NS              centos02.accp.com.
centos02        A               192.168.100.20
www             A               192.168.100.10
[root@centos02 ~]# vim
/var/named/bdqn.com.zone
$TTL            86400
@               SOA             bdqn.com.      root.bdqn.com.
(
                2023031415
                1H
                15M
                1W
                1D
)
@               NS              centos02.bdqn.com.
centos02        A               192.168.100.20
www             A               192.168.100.10

4）启动服务

[root@centos02 ~]# systemctl start named
[root@centos02 ~]# systemctl enable named

5）客户端解析域名

6）客户端验证域名访问tomcat
