java+tomcat+apache安装整合，启动/关闭，添加开机启动服务

安装java1.8

#yum update    服务器更新源码包

#rpm -qa |grep -E '^open[jre|jdk]|j[re|dk]'  搜索任何版本的已安装JDK组件

java-1.8.0-openjdk-headless-1.8.0.60-2.b27.el7_1.x86_64

pygobject2-2.28.6-11.el7.x86_64

pygobject3-base-3.8.2-6.el7.x86_64

java-1.8.0-openjdk-1.8.0.60-2.b27.el7_1.x86_64

openjpeg-libs-1.5.1-10.el7.x86_64

gobject-introspection-1.36.0-4.el7.x86_64

#java -version    查看已安装的java版本

#yum remove java-1.7.0-openjdk    卸载之前的版本的java

yum安装java1.8

# yum search jdk

#yum -y install java-1.8.0-openjdk

rpm源码包安装：

#wget http://download.oracle.com/otn-pub/java/jdk/8u60-b27/jdk-8u60-linux-x64.rpm?AuthParam=1443602484_eec243d56fc3dd67d4f7b8a519fd7495

#rpm -ivh xxx

编译安装：

#wget http://download.oracle.com/otn-pub/java/jdk/8u60-b27/jdk-8u60-linux-x64.tar.gz?AuthParam=1443602555_3d37647b877dfd6a5fbdcbc561021958

#tar zxvf xxx -C /root/

#cd  /root/xx

#cp -rp jre1.7.-_05 /usr/local

#vi /etc/profile        配置全局环境

    JAVA_HOME=/usr/local/xxx

    CLASSPATH=$CLASSPATH:$JAVA_HOME/lib

    PATH=$JAVA_HOME/bin:$PATH

测试java是否安装成功

#chown -R root.root /usr/local/xxx/

#java -version

如果运行java报错：

error :/usr/lib/libjvm.so: cannot restore segment prot after reloc: Permission denied .
use the command:
chcon -t textrel_shlib_t /usr/lib/libjvm.so

是selinux导致的

    #setenforce 0

二、安装tomcat7

#wget http://apache.mirror.digitalpacific.com.au/tomcat/tomcat-7/v7.0.64/bin/apache-tomcat-7.0.64.tar.gz

#tar zxvf xxx    解压之后就是二进制文件，无需安装。直接将目录移动到/usr/local目录即可

#mv xxx /usr/local/tomcat    

#vim /usr/local/tomcat/bin/catalisna.sh    在tomcat启动脚本中设置环境变量

    JAVA_HOME=/usr/java/jdk1.8.0xx            使其支持java，添加此行

#vim /etc/profile

    CATALINA_HOME=/usr/local/tomcat/

    PATH=$JAVA_HOME/bin:/usr/local/tomcat/bin/:$PATH        设置环境变量

    退出当前shell，重进后该配置生效

or

#. /etc/profile    使新的环境变量生效

手动启动/关闭/重启tomcat

#/usr/local/tomcat/bin/catalina.sh

#netstat -lnp |grep 80    发现80开头的端口，即表示tomcat启动成功

#/usr/local/tomcat/bin/catalina.sh stop/restart

#/usr/local/tomcat/bin/shutdown.sh    也可以关闭tomcat

设置systemctl开机自启动服务

#vim /lib/systemd/system/tomcat.service

[Unit]

Description=tomcat

After=network.target

[Service]

Type=forking

ExecStart=/usr/local/tomcat/bin/catalina.sh start  

ExecReload=/usr/local/tomcat/bin/catalina.sh restart  

ExecStop=/usr/local/tomcat/bin/catalina.sh  stop  

PrivateTmp=true  

   

[Install]  

WantedBy=multi-user.target

#systemctl enable tomcat.service    链接到systemctl开机自启动服务

#systemctl start/stop/restart tomcat.service

三、tomcat+apache整合

整合方式三种：

01 JK方式

02 http_proxy方式    

03 ajp_proxy方式

http_proxy方式需要的模块：

mod_proxy.so和mod_prxy_http.so

默认mod_proxy.so已经安装，只需安装mod_proxy_http.so模块

#ls /usr/lib64/httpd/modules/mod_proxy_http.so   

#ls /usr/lib64/httpd/modules/mod_proxy.so

将该模块添加到httpd.conf配置文件中

#vim /etc/httpd/conf/httpd.conf

    LoadModule  proxy_http_module modules/mod_proxy_http.so

#service httpd restart     重启apache服务
