[root@运维网 ~]# cat /proc/cpuinfo| grep "cpu cores"| uniq
cpu cores    : 2
[root@运维网 ~]# free -m

[root@运维网 /]# systemctl disable firewalld  禁止防火墙开机启动
[root@运维网 /]# vi /etc/selinux/config  禁止selinux开机启动
#This file controls the state of SELinux on the system.
#SELINUX= can take one of these three values:
#enforcing - SELinux security policy is enforced.
#permissive - SELinux prints warnings instead of enforcing.
#disabled - No SELinux policy is loaded.
SELINUX=disabled #修改为disabled

　　yum install lrzsz  net-tools  wget vim 安装常用工具
　　2、部署JDK
https://download.oracle.com/otn-pub/java/jdk/8u201-b09/42970487e3af4f5aa5bca3f542482c60/jdk-8u201-linux-x64.tar.gz
[root@运维网 /]# cd tools/
[root@运维网 tools]# pwd
/tools
[root@运维网 tools]#
[root@运维网 tools]# wget https://download.oracle.com/otn-pub/java/jdk/8u201-b09/42970487e3af4f5aa5bca3f542482c60/jdk-8u201-linux-x64.tar.gz
[root@运维网 tools]# rpm -aq | grep java
[root@运维网 tools]#
[root@运维网 tools]# ls
jdk-8u201-linux-x64.tar.gz
[root@运维网 tools]# tar xvf jdk-8u201-linux-x64.tar.gz
gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now
[root@运维网 tools]#
换种方式下载


[root@bogon tools]# tar xvf jdk-8u201-linux-x64.tar.gz -C /usr/local/#可以解压了
[root@bogon tools]# cd /usr/local/
[root@bogon local]# ls
bin  etc  games  include jdk1.8.0_201  lib  lib64  libexec  sbin  share  src
[root@bogon local]#
[root@bogon local]# mv jdk1.8.0_201/ jdk
[root@bogon local]# ls
bin  etc  games  include  jdk lib  lib64  libexec  sbin  share  src
[root@bogon local]#
[root@bogon local]# vim /etc/profile#添加环境变量
#jdk配置
export JAVA_HOME=/usr/local/jdk/
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
[root@bogon local]# source /etc/profile#立即生效
[root@bogon local]# java -version

[root@bogon bin]#

根据路径去找口令，拿过来继续
[root@bogon bin]# more /usr/local/tomcat/webapps/jenkins/secrets/initialAdminPassword

[root@bogon bin]#
好了根据提示一路走下去就可以
