JDK 安装步骤
下载 http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

rpm -ivh jdk-8u171-linux-x64.rpm 

cd ~
vim .bash_profile
输入命令添加环境变量：
export JAVA_HOME=/usr/java/jdk1.8.0_171-amd64
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
PATH=$JAVA_HOME/bin:$PATH:$HOME/bin
export PATH

[root@localhost ~]# java -version
java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)

[root@localhost ~]# javac -version
javac 1.8.0_171
-------------------
Tomcat安装
[root@localhost soft]# wget http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.31/bin/apache-tomcat-8.5.31.tar.gz
[root@localhost soft]# tar -zxvf apache-tomcat-8.5.31.tar.gz 
[root@localhost data]# mv apache-tomcat-8.5.31 tomcat-8801
tomcat-8801
端口 8801 8105 8543  8201
端口 8802 8106 8544  8202
端口 8803 8107 8545  8203  server
端口 8804 8108 8546  8204  job
端口 8088 8104 8542  8200  Dubbo
="8801" protocol="HTTP/1.1" connectionTimeout="20000" 
redirectPort="8543" URIEncoding="UTF-8"  />

[root@localhost bin]# vim catalina.sh
修改/apache-tomcat-8.5.16/bin/catalina.sh  
在catalina.sh中的 “#!/bin/sh” 下面添加如下代码：
if [[ "$JAVA_OPTS" != *-Djava.security.egd=* ]]; then
    JAVA_OPTS="$JAVA_OPTS -Djava.security.egd=file:/dev/./urandom"
fi

在
# Get standard environment variables
PRGDIR=`dirname "$PRG"`
下添加下面代码
#设置记录CATALINA_PID。
#该设置会在启动时候bin下新建一个CATALINA_PID文件
#关闭时候从CATALINA_PID文件找到pid，kill。。。同时删除CATALINA_PID文件
if [ -z "$CATALINA_PID" ]; then
      CATALINA_PID=$PRGDIR/CATALINA_PID
fi

vim tomcat的shutdown.sh文件,在最后一行加上-force； 
例：exec "$PRGDIR"/"$EXECUTABLE" stop -force "$@"
--------------------------
防火墙开放端口
开放端口
/sbin/iptables -I INPUT -p tcp --dport 80 -j ACCEPT
/sbin/iptables -I INPUT -p tcp --dport 22 -j ACCEPT
/sbin/iptables -I INPUT -p tcp --dport 3306 -j ACCEPT
/sbin/iptables -I INPUT -p tcp --dport 6379 -j ACCEPT
/sbin/iptables -I INPUT -p tcp --dport 8801 -j ACCEPT

/sbin/iptables -I INPUT -p tcp --dport 8088 -j ACCEPT
/sbin/iptables -I INPUT -p tcp --dport 2181 -j ACCEPT
/sbin/iptables -I INPUT -p tcp --dport 2182 -j ACCEPT
/sbin/iptables -I INPUT -p tcp --dport 2183 -j ACCEPT
/sbin/iptables -I INPUT -p tcp --dport 9952 -j ACCEPT

/sbin/iptables -I INPUT -p tcp --dport 2181 -j ACCEPT
/sbin/iptables -I INPUT -p tcp --dport 2182 -j ACCEPT
/sbin/iptables -I INPUT -p tcp --dport 2183 -j ACCEPT
/sbin/iptables -I INPUT -p tcp --dport 80 -j ACCEPT
/sbin/iptables -I INPUT -p tcp --dport 9952 -j ACCEPT
/sbin/iptables -I INPUT -p tcp --dport 6379 -j ACCEPT
/sbin/iptables -I INPUT -p tcp --dport 8801 -j ACCEPT

保存之前输入已开放端口号语句的命令
/etc/rc.d/init.d/iptables save
查看打开端口命令
/etc/init.d/iptables status

[root@ora mysql]# scripts/mysql_install_db --user=mysql
[root@ora mysql]# cp support-files/mysql.server /etc/init.d/mysql
[root@ora etc]# vim my.cnf
[mysqld]下
basedir=/longfor_data/application/mysql
1）修改字符集为UTF8
#vi /etc/my.cnf
在[client]下面添加 default-character-set = utf8
在[mysqld]下面添加 character_set_server = utf8
修改完重启：#service  mysql  restart 
2）增加错误日志
#vi /etc/my.cnf
在[mysqld]下面添加：
log-error = /usr/local/mysql/log/error.log
general-log-file = /usr/local/mysql/log/mysql.log
修改完重启：#service  mysql  restart 
3) 设置为不区分大小写，linux下默认会区分大小写。
#vi /etc/my.cnf
在[mysqld]下面添加：
lower_case_table_name=1
修改完重启：#service  mysql  restart 

[root@ora mysql]# chkconfig  mysql on
[root@ora mysql]# service  mysql  start
[root@ora ~]# cd 
[root@ora ~]# vim .bash_profile 
export PATH=/longfor_data/application/mysql/bin:$PATH

#auth       required    pam_shells.so
法1：执行命令setsebool -P ftp_home_dir on命令或者执行 setsebool -P ftpd_disable_trans on 命令，
然后执行service vsftpd restart命令重启vsftpd服务
法2：关闭selinux，修改/etc/selinux/config文件或/etc/syscofnig/selinux设置SELINUX= disabled ，然后重启
[root@node3 pam.d]# mkdir /lhdata/data/ftp/qdpftp
[root@node3 pam.d]# chown -R qdpftp:qdpftp /lhdata/data/ftp/qdpftp
[root@node3 pam.d]# chmod -R 777 /lhdata/data/ftp/qdpftp
[root@localhost lhdata]# service vsftpd restart
测试登录FTP
[c:\~]$ ftp 192.168.15.151 或浏览器   ftp://192.168.15.151
