Linux怎么查看WEB服务器安装没有

楼下两位的答案只适用于web服务器监听80端口，且WEB服务已经启动
你可以尝试分别输入 nginx / tomcat / >

这个要根据自己的实际需求应对选择：

对于PHP网站程序而言，windows服务器和linux服务器基本都可以，linux速度较好，不过也是相对而言的，现在windows服务器加载zend等加速组件，普通网站肉眼也是没什么区别的。

对于asp 和net网站而言，windows是独一无二的选择，因为linux还不支持asp等脚本运行。

所以windows服务器另外有个名称，叫做全能服务器，特别是在自己没有确定用什么程序，或者说要建多个网站，程序不同的情况下，windows服务器是首选。

1开始说明
本教程中使用的IP地址是1921680100，主机名称为Server1examplecom 这些设置可能会有所不同，你需要根据不同情况进行修改。
CentOS 62下安装MySQL
2开始安装MySQL5
首先我们应该先用下面的命令安装MySQL：
yum install mysql mysql-server
然后我们需要创建MySQL系统的启动键链接启动MySQL服务器，这样以便于MySQL在系统启动时自动启动
chkconfig --levels 235 mysqld on
/etc/initd/mysqld start
为MySQL root帐户设置密码：
mysql_secure_installation
会出现下面的一系列提示：
root@server1 ~]# mysql_secure_installation
NOTE： RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MySQL to secure it， we'll need the current
password for the root user If you've just installed MySQL， and
you haven't set the root password yet， the password will be blank，
so you should just press enter here
Enter current password for root (enter for none)：
OK， successfully used password， moving on
Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation
Set root password [Y/n] <-- ENTER
New password： <-- yourrootsqlpassword
Re-enter new password： <-- yourrootsqlpassword
Password updated successfully!
Reloading privilege tables
Success!
By default， a MySQL installation has an anonymous user， allowing anyone
to log into MySQL without having to have a user account created for
them This is intended only for testing， and to make the installation
go a bit smoother You should remove them before moving into a
production environment
Remove anonymous users [Y/n] <-- ENTER
Success!
Normally， root should only be allowed to connect from 'localhost' This
ensures that someone cannot guess at the root password from the network
Disallow root login remotely [Y/n] <-- ENTER
Success!
By default， MySQL comes with a database named 'test' that anyone can
access This is also intended only for testing， and should be removed
before moving into a production environment
Remove test database and access to it [Y/n] <-- ENTER
- Dropping test database
Success!
- Removing privileges on test database
Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately
Reload privilege tables now [Y/n] <-- ENTER
Success!
Cleaning up
All done! If you've completed all of the above steps， your MySQL
installation should now be secure
Thanks for using MySQL!
[root@server1 ~]#
CentOS 62下安装Apache
3安装阿帕奇2
Apache2的是作为一个CentOS的软件包，因此我们可以直接用下面命令安装它：
yum install >如果有安装web服务那么肯定会开启80端口
所以优先查看服务器是否在监听80端口
netstat
-an|grep
:80
也可以直接访问ip地址；
举个例子：Apache
web服务是否安装的几个检查命令
ps
aux
|grep
