ldapjdk.noarch : The Mozilla LDAP Java SDK

执行安装命令：yum install java-1.8.0-openjdk

安装成功后，默认安装路径在/usr/lib/jvm/下边，
如/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.144-0.b01.el6_9.x86_64

查看安装路径(如下所示)：
which java
ls -lrt /usr/bin/java

[root@preproduct1 ~]# which java

/usr/bin/java

[root@preproduct1 ~]# echo $JAVA_HOME

/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-1.el7_6.x86_64

[root@preproduct1 ~]# ls -lrt /usr/bin/java

lrwxrwxrwx 1 root root 22 Feb 13 10:40 /usr/bin/java -> /etc/alternatives/java

[root@preproduct1 ~]# ls -lrt /etc/alternatives/java

lrwxrwxrwx 1 root root 73 Feb 13 10:40 /etc/alternatives/java -> /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-1.el7_6.x86_64/jre/bin/java

[root@preproduct1 ~]# cd /usr/lib/jvm

[root@preproduct1 /usr/lib/jvm]# ll

lrwxrwxrwx 1 root root   29 Feb 13 10:40 jre-openjdk -> /etc/alternatives/jre_openjdk

验证java是否安装成功

查看java版本：java -version

# java -version

openjdk version "1.8.0_191"

OpenJDK Runtime Environment (build 1.8.0_191-b12)

OpenJDK 64-Bit Server VM (build 25.191-b12, mixed mode)

查看java是否可用：javac
```
# javac

-bash: javac: command not found
```
错误原因：默认安装完只有运行环境，java安装目录下只有jre文件夹

安装开发环境yum install java-1.8.0-openjdk-devel.x86_64
安装完可看到java安装目录下出现bin、lib等文件夹:

[root@preproduct1 /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-1.el7_6.x86_64]# l

total 20

drwxr-xr-x 2 root root 4096 Feb 13 10:44 bin

drwxr-xr-x 3 root root 4096 Feb 13 10:44 include

drwxr-xr-x 4 root root 4096 Feb 13 10:40 jre

drwxr-xr-x 3 root root 4096 Feb 13 10:44 lib

drwxr-xr-x 2 root root 4096 Feb 13 10:44 tapset

再次输入javac说明安装成功

# javac

Usage: javac <options> <source files>

where possible options include:

  -g                         Generate all debugging info

  -g:none                    Generate no debugging info

  -g:{lines,vars,source}     Generate only some debugging info

  -nowarn                    Generate no warnings

  -verbose                   Output messages about what the compiler is doing

  -deprecation               Output source locations where deprecated APIs are use

  -classpath <path>          Specify where to find user class files and annotationocessors

  -cp <path>                 Specify where to find user class files and annotationocessors

  -sourcepath <path>         Specify where to find input source files

设置环境变量
修改/etc/profile文件：vi /etc/profile
在profile文件末尾新增如下内容：

#set java environment

   JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-1.el7_6.x86_64

   JRE_HOME=$JAVA_HOME/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

使环境变量生效：source /etc/profile

[root@preproduct1 /usr/lib/jvm]# cd /usr/lib/jvm

[root@preproduct1 /usr/lib/jvm]# cd java-1.8.0-openjdk-1.8.0.191.b12-1.el7_6.x86_64/

[root@preproduct1 /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-1.el7_6.x86_64]# source /etc/profile

[root@preproduct1 /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-1.el7_6.x86_64]# echo $JAVA_HOME

/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-1.el7_6.x86_64

至此jdk安装成功
