Linux运维 --- Tomcat 服务配置

Tomcat是Apache软件基金会的Jakarta项目中开发的一个Servlet容器，实现了对Servlet和JavaServerPage（JSP）的支持，Tomcat本身也是一个HTTP服务器，Tomcat主要用来解析JSP语言、HTML格式的网页页面。

本实验需要用到的软件：

apache-tomcat-8.5.57.tar.gz

jdk-8u261-linux-i586.tar.gz

安装JDK

[root@localhost ~]# yum install glibc.i686 -y
[root@localhost ~]# cd /usr/local
[root@localhost local]# mkdir {java,tomcat}
[root@localhost local]# cd ~
[root@localhost ~]# tar -xf jdk-8u261-linux-i586.tar.gz
[root@localhost ~]# mv jdk1.8.0_261/ /usr/local/java
[root@localhost ~]# vim /etc/profile     # 在配置文件最后添加如下三行JDK环境
export JAVA_HOME=/usr/local/java/jdk1.8.0_261
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib

[root@localhost ~]# source /etc/profile  
[root@localhost ~]# which java
/usr/local/java/jdk1.8.0_261/bin/java
[root@localhost ~]# java -version
java version "1.8.0_261"
Java(TM) SE Runtime Environment (build 1.8.0_261-b12)
Java HotSpot(TM) Client VM (build 25.261-b12, mixed mode)
[root@localhost ~]#

安装Tomcat

[root@localhost ~]# tar -xf apache-tomcat-8.5.57.tar.gz 
[root@localhost ~]# mv apache-tomcat-8.5.57 /usr/local/tomcat
[root@localhost ~]# echo 'export TOMCAT_HOME=/usr/local/tomcat' >> /etc/profile   # 添加Tomcat环境
[root@localhost ~]# source /etc/profile
[root@localhost ~]# tail -4 /etc/profile     # 查看倒数4行内容
export JAVA_HOME=/usr/local/java/jdk1.8.0_261
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
export TOMCAT_HOME=/usr/local/tomcat

[root@localhost ~]# /usr/local/tomcat/apache-tomcat-8.5.57/bin/startup.sh   # 启动Tomcat
Using CATALINA_BASE:   /usr/local/tomcat/apache-tomcat-8.5.57
Using CATALINA_HOME:   /usr/local/tomcat/apache-tomcat-8.5.57
Using CATALINA_TMPDIR: /usr/local/tomcat/apache-tomcat-8.5.57/temp
Using JRE_HOME:        /usr/local/java/jdk1.8.0_261
Using CLASSPATH:       /usr/local/tomcat/apache-tomcat-8.5.57/bin/bootstrap.jar:/usr/local/tomcat/apache-tomcat-8.5.57/bin/tomcat-juli.jar
Tomcat started.

配置SELinux 和防火墙

[root@localhost ~]# setenforce 0
[root@localhost ~]# firewall-cmd --zone=public --add-port=8080/tcp --permanent
success
[root@localhost ~]# getenforce
Permissive

在浏览器中输入：192.168.203.129:8080，即可访问Tomcat默认页面

基于端口的虚拟机，修改Tomcat的server.xml配置文件，将port="8080"改成port="80"，还可以在下面继续添加端口

 [root@localhost ~]# cd /usr/local/tomcat/apache-tomcat-8.5.57/conf/
 [root@localhost conf]# vim server.xml 
   <Connector port="80" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

      # 重启Tomcat
[root@localhost conf]# /usr/local/tomcat/apache-tomcat-8.5.57/bin/shutdown.sh
[root@localhost conf]# /usr/local/tomcat/apache-tomcat-8.5.57/bin/startup.sh

通过Tomcat部署zrlog博客网站

下载zrlog软件包

[root@localhost ~]# wget http://dl.zrlog.com/release/zrlog-2.1.3-b5f0d63-release.war?attname=ROOT.war&ref=index
[root@localhost ~]# ls | grep *.war
zrlog-2.1.3-b5f0d63-release.war?attname=ROOT.war
[root@localhost ~]# cd /usr/local/tomcat/apache-tomcat-8.5.57/webapps
[root@localhost webapps]# cd 
[root@localhost ~]# mv zrlog-2.1.3-b5f0d63-release.war\?attname\=ROOT.war /usr/local/tomcat/apache-tomcat-8.5.57/webapps/zrlog.war
[root@localhost ~]# cd /usr/local/tomcat/apache-tomcat-8.5.57/webapps/
[root@localhost webapps]# ls
docs  examples  host-manager  manager  ROOT  zrlog  zrlog.war
[root@localhost webapps]# mv ROOT ROOT.bak
[root@localhost webapps]# mv zrlog ROOT
[root@localhost webapps]#

安装mariadb数据库

[root@localhost ~]# yum install mariadb mariadb-server
...........省略部分安装步骤..............
Updated:
  mariadb.x86_64 1:5.5.65-1.el7          mariadb-server.x86_64 1:5.5.65-1.el7         
Dependency Updated:
  mariadb-libs.x86_64 1:5.5.65-1.el7                                                   
Complete!
[root@localhost ~]# systemctl start mariadb    # 启动Mariadb数据库
[root@localhost ~]# systemctl enable mariadb
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.
[root@localhost ~]# mysql_secure_installation    # 初始化Mariadb数据库

[root@localhost ~]#

将MySQL服务加入到防火墙并重启

[root@localhost ~]# firewall-cmd --permanent --add-service=mysql
success
[root@localhost ~]# firewall-cmd --reload
success
[root@localhost ~]#

在Mariadb数据库中创建zrlog数据库、zrlog用户，并给用户授权

[root@localhost ~]# mysql -uroot -p123456
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 10
Server version: 5.5.65-MariaDB MariaDB Server

Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]> create database zrlog;
Query OK, 1 row affected (0.05 sec)

MariaDB [(none)]> grant all on zrlog.* to 'zrlog'@'192.168.203.129' identified by '123456';
Query OK, 0 rows affected (0.03 sec)

MariaDB [(none)]> quit

用户：zrlog ，密码：123456 ，授权host主机：192.168.203.129（如果上面没有修改端口，则默认是8080端口）

打开浏览器访问：http://192.168.203.129:80（tomcat端口）

配置管理员账号信息

至此，Linux系统下安装Tomcat并完成部署网站！
