安装tomcat之前需安装jdk

下载地址：http://www.oracle.com/technetwork/cn/java/javase/downloads/jdk8-downloads-2133151-zhs.html   #下载rpm包安装

安装jdk步骤：

[root@app-server ~]# rpm -ivh  jdk-8u102-linux-x64.rpm

[root@app-server ~]# vi /etc/profile  #添加环境变量

export JAVA_HOME=/usr/java/jdk1.8.0_102   #JDK默认的安装目录
export JAVA_BIN=/usr/java/jdk1.8.0_102/bin
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export JAVA_HOME JAVA_BIN PATH CLASSPATH

[root@app-server ~]# source /etc/profile

[root@app-server ~]# java -version
java version "1.8.0_102"
Java(TM) SE Runtime Environment (build 1.8.0_102-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.102-b14, mixed mode) java -version
java version "1.8.0_102"
Java(TM) SE Runtime Environment (build 1.8.0_102-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.102-b14, mixed mode)

安装tomcat步骤：

1、压到本地目录 如：/usr/local
2、添加环境变量

[root@app-server ~]# vi /etc/profile
export CATALINA_HOME=/usr/local/apache-tomcat-7.0.73
root@app-server ~]# source /etc/profile
3、启动tocmat

[root@app-server ~]# /usr/local/apache-tomcat-7.0.73/bin/satrtup.sh
Using CATALINA_BASE:   /usr/local/apache-tomcat-7.0.73
Using CATALINA_HOME:   /usr/local/apache-tomcat-7.0.73
Using CATALINA_TMPDIR: /usr/local/apache-tomcat-7.0.73/temp
Using JRE_HOME:        /usr/java/jdk1.8.0_102
Using CLASSPATH:       /usr/local/apache-tomcat-7.0.73/bin/bootstrap.jar:/usr/local/apache-tomcat-7.0.70/bin/tomcat-juli.jar
4、配置管理员
[root@app-server ~]# vi /usr/local/apache-tomcat-7.0.70/conf/tomcat-users.xml 

修改默认管理员
<tomcat-users>
  <role rolename="admin-gui"/>
  <role rolename="manager-script"/>
  <role rolename="manager-jmx"/>
  <role rolename="admin-script"/>
  <role rolename="manager-status"/>
  <role rolename="manager-gui"/>
  <user username="admin" password="1234" roles="manager-gui,manager-script,manager-jmx,manager-status,admin-script,admin-gui"/>
</tomcat-users>

rhel7 开机自动启动(systemctl方式配置)

[root@app-server ~]# cd $CATALINA_HOME
[root@app-server apache-tomcat-7.0.73]# touch tomcat.pid

[root@app-server bin]# vi setenv.sh
#set java runtime environment variable 
export JAVA_HOME=/usr/java/jdk1.8.0_102
export JRE_HOME=/usr/java/jdk1.8.0_102/jre
 
# set APR 
export LD_LIBRARY_PATH=/usr/local/apr/lib   //需要安装APR

#add tomcat pid 
CATALINA_PID="$CATALINA_HOME/tomcat.pid"
 
#add java opts 
JAVA_OPTS="-server -Xms1024m -Xmx4096m -XX:PermSize=256M -XX:MaxNewSize=1024m -XX:MaxPermSize=512m -Djava.awt.headless=true"
