tomcat安装及使用

1.上传java程序包到/user/local/src下

2.创建tomcat目录

mkdir /mnt/java
mkdir /mnt/tomcat

3.创建程序部署目录

mkdir-p /mnt/webapps

4.配置java环境

1) 程序包解压

cd /user/local/src
tar xvf jdk-8u152-linux-x64.tar.gz

2) 将解压文件转移到java目录

mv jdk1.8.0_152/* /mnt/java/

3)修改系统环境变量

vi /etc/profile

export JAVA_HOME=/mnt/java
export JRE_HOME=/mnt/java/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH

4) 修改系统环境变量配置文件

source /etc/profile

5.验证java环境是否生效

java -version
java version"1.8.0_152"
Java(TM) SERuntime Environment (build 1.8.0_152-b16)
Java HotSpot(TM)64-Bit Server VM (build 25.152-b16, mixed mode)

6.安装tomcat

1)创建用户

groupadd tomcat
useradd -g tomcat tomcat

2)添加用户权限

chown tomcat.tomcat /mnt/tomcat
chown tomcat.tomcat /mnt/webapps

3)程序包解压

su - tomcat
上传tomcat程序包到/user/local/src下（上传路径自己设定）
cd /user/local/src
tar xvf apache-tomcat-8.0.47.tar.gz(如不能解压请将程序包权限改为tomcat)

4)将解压文件转移到tomcat目录

mv apache-tomcat-8.0.47/* /mnt/tomcat/

5)修改tomcat配置文件

cd /mnt/tomcat/
vi conf/server.xml

<Server port="8006" shutdown="SHUTDOWN">
  <Listener className="org.apache.catalina.startup.VersionLoggerListener" />
    <Connector port="38881" protocol="HTTP/1.1"
              connectionTimeout="20000"
              redirectPort="8443" />
<Connector port="8010" protocol="AJP/1.3" redirectPort="8445" />
      <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="false">
<Host name="localhost"  appBase="webapps"
      <Context path="/" docBase="/mnt/webapps" reloadable="false" crossContext="true" />
</Host>

reloadable:是否自动加载新增或改变的class文件

6)启动tomcat

cd /mnt/tomcat/bin/
./catalina.sh start

7)查看tomcat日志

tail -f /mnt/tomcat/logs/catalina.out

8)访问地址

http://ip:port/project_name

9)添加ssl证书

vi /mnt/tomcat/conf/server.xml

<Connector port="8080"protocol="org.apache.coyote.http11.Http11NioProtocol"
               maxThreads="150"SSLEnabled="true" scheme="https" secure="true"
clientAuth="false" sslProtocol="TLS"KeystoreFile="证书路径"KeystorePass="证书密码" type="RSA" />
