centos7.X安裝jdk及配置環境變量及wget下載tomcat

好久沒有配置過jdk環境，基本都忘了，現在安裝記錄下

1. 查案是否自帶JDK

    rpm -qa | grep java

2. 如果自帶JDK，刪除

    #rpm -e --nodeps <java進行>

    如： rpm -e --nodeps java-1.8.0-openjdk-1.8.0.102-4.b14.el7.x86_64
           rpm -e --nodeps java-1.8.0-openjdk-headless-1.8.0.102-4.b14.el7.x86_64
           rpm -e --nodeps java-1.7.0-openjdk-headless-1.7.0.111-2.6.7.8.el7.x86_64
           rpm -e --nodeps java-1.7.0-openjdk-1.7.0.111-2.6.7.8.el7.x86_64

3. 查看是否已刪除

    rpm -qa | grep java

4. 下載JDK

  4.1 通過wget安裝

    4.1.1 下載wget

        #yum -y install wget

     4.1.2 下載jdk並解壓

        #wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u141-b15/336fa29ff2bb4ef291e347e091f7f4a7/jdk-8u141-linux-x64.tar.gz"

   

    4.1.3 解壓

        #tar -zxvf jdk-8u141-linux-x64.tar.gz

5. 配置環境變量

    # vi /etc/profile

JAVA_HOME=/usr/local/tools/jdk1.8.0_141
JRE_HOME=/usr/local/tools/jdk1.8.0_141/jre
CLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
export JAVA_HOME JRE_HOME CLASS_PATH PATH

#source /etc/profile

 

6. tomcat下載

tomcat庫：https://mirrors.cnnic.cn/apache/tomcat/

#wget https://mirrors.cnnic.cn/apache/tomcat/tomcat-9/v9.0.13/bin/apache-tomcat-9.0.13.tar.gz

#tar -zxvf apache-tomcat-9.0.13.tar.gz

#vim server.xml

增加應用連接在host節點，/data/monitor爲項目目錄

<Context docBase="/data/monitor" path="/monitor" reloadable="false"/>

啓動tomcat

/home/tomcat/bin/startup.sh

   

2. 安裝nginx

#yum -y install gcc automake autoconf libtool make

#yum -y install gcc gcc-c++

#yum -y install pcre-devel

# yum install zlib

#yum -y install pcre-devel openssl openssl-devel

#cd /usr/local/soft

#wget http://nginx.org/download/nginx-1.1.10.tar.gz

#tar -zxvf nginx-1.1.10.tar.gz -C /usr/local/soft/

# cd nginx-1.1.10

#./configure 

#make && make install

2.配置nginx
#cd /usr/local/nginx/conf
