Centos7
1、SSH默认端口
1)、vi /etc/ssh/sshd_config
#Port 22 //这行去掉#号
Port 2222 //下面添加这一行
service sshd restart
service sshd status
servicservice sshd restarte sshd restart
service sshd restart
2)、修改SELinux
semanage port -l | grep ssh //命令查看
semanage port -a -t ssh_port_t -p tcp 2222 //添加端口到SELinux
3)、默认防火墙firewalld 禁用
systemctl stop firewalld.service //禁用
systemctl disable firewalld.service //禁用
安装iptables防火墙
yum install iptables-services #安装
vi /etc/sysconfig/iptables
增加一行
-A INPUT -p tcp -m state --state NEW -m tcp --dport 2222 -j ACCEPT
如果没有安装iptables可以直接用yum安装
yum install -t iptables
检查iptables服务的状态，
service iptables status
如果出现“iptables: Firewall is not running”,说明没有启动或没有规则
启动iptables服务
service iptables start
保存重启
service iptables save
service iptables restart
代码如下:
/etc/rc.d/init.d/iptables stop 关闭防火墙
最后：
在根用户下输入setup，进入一个图形界面，选择Firewall configuration，进入下一界面，选择Security Level为Disabled，保存。重启即可。
2、
1)、新建用户
useradd sf2016 //新用户
passwd sf2016 //设密码
2)、JDK64安装
chmod 755 jdk-linux_64.rpm //root状态
rpm -ivh dk-linux_64.rpm //root状态
vi .bash_profile //sf2016 (非root用户使用)
在bash_profile文件最后添加以下语句：
#set java environment
JAVA_HOME=/usr/java/jdk1.7.0_23
export JAVA_HOME
java -version
3)、Tomcat安装
tar -zxvf apache-tomcat-xxx.tar.gz
apache-tomcat-xxx/bin/ ./startup.sh //启动
ps -ef |grep tomcat
ps -ef |grep 8080
http://l92.168.11.112:8080
tomcat端口修改
conf/server.xml
<Connector port="8000" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />
http://l92.168.11.112:8080
3、mysql 安装
http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-server-5.6.21-1.rhel5.x86_64.rpm
http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-devel-5.6.21-1.rhel5.x86_64.rpm
http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-client-5.6.21-1.rhel5.x86_64.rpm
[root@linuxidc tools]# wget http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-server-5.6.21-1.rhel5.x86_64.rpm
[root@linuxidc tools]# wget http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-devel-5.6.21-1.rhel5.x86_64.rpm
[root@linuxidc tools]# wget http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-client-5.6.21-1.rhel5.x86_64.rpm
1)、mysql_service安装
rpm -ivh MySQL-server-5.5.8-1.rhel5.i386.rpm
2、安装iptables防火墙
yum install iptables-services #安装
vi /etc/sysconfig/iptables #编辑防火墙配置文件
# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT
:wq! #保存退出
systemctl restart iptables.service #最后重启防火墙使配置生效
systemctl enable iptables.service #设置防火墙开机启动
