tomcat安装
安装tomcat
安装如下：
[root@localhost ~]# iptables -F
[root@localhost ~]# setenforce 0
[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# java -version
openjdk version "1.8.0_131"
OpenJDK Runtime Environment (build 1.8.0_131-b12)
OpenJDK 64-Bit Server VM (build 25.131-b12, mixed mode)
[root@localhost ~]# rpm -qa |grep -i opten jdk
grep: jdk: 没有那个文件或目录
[root@localhost ~]# rpm -qa |grep -i optenjdk
[root@localhost ~]# rpm -qa |grep -i openjdk
java-1.7.0-openjdk-1.7.0.141-2.6.10.5.el7.x86_64
java-1.8.0-openjdk-1.8.0.131-11.b12.el7.x86_64

java-1.8.0-openjdk-headless-1.8.0.131-11.b12.el7.x86_64
[root@localhost ~]# rpm -e java-1.7.0-openjdk
[root@localhost ~]# rpm -e java-1.7.0-openjdk-headless
[root@localhost ~]# rpm -e java-1.8.0-openjdk
错误：依赖检测失败：
java >= 1.5 被 (已安裝) jline-1.0-8.el7.noarch 需要
java-1.8.0-openjdk 被 (已安裝) icedtea-web-1.6.2-4.el7.x86_64 需要
[root@localhost ~]# rpm -e java-1.8.0-openjdk --nodeps //忽略依赖关系
[root@localhost ~]# rpm -e java-1.8.0-openjdk-headless
[root@localhost ~]# rpm -qa |grep -i openjdk
（方法二：卸载Java
[root@localhost html]# java -version
openjdk version "1.8.0_131"
OpenJDK Runtime Environment (build 1.8.0_131-b12)
OpenJDK 64-Bit Server VM (build 25.131-b12, mixed mode)
[root@localhost html]# which java
/usr/bin/java
[root@localhost html]# rm -rf /usr/bin/java
[root@localhost html]# java -version
-bash: /usr/bin/java: 没有那个文件或目录
