This article introduces in detail the process of installing and configuring the LAMP service in the CentOS6.4 system, that is, installing Apache+PHP+Mysql. It refers to the settings of online experts. Other Linux distribution systems can refer to it~
Some of the command operations in this article require root permissions. Enter the ‘’ command and then enter the password to switch the root identity.
Settings file allows port 80 and port 3306. Because port 80 is the port used by the http protocol, if the firewall blocks port 80, the website cannot be accessed from the outside even after it is configured. Port 3306 is the default port of the MySql database. Open the iptables file using VIM and add rules:
<span 1</span> <span 打开iptables文件进行修改 </span><span 2</span> vim /etc/sysconfig/<span iptables </span><span 3</span> <span 4</span> <span 加入下列两行 </span><span 5</span> -A INPUT -p tcp -m state --state NEW -m tcp --dport <span 80</span> -<span j ACCEPT </span><span 6</span> -A INPUT -p tcp -m state --state NEW -m tcp --dport <span 3306</span> -j ACCEPT
After adding, the file should be as shown below. If the file has been modified before, it may be slightly different from the author’s picture:
2. Close SELINUX
( provided in the 2.6 version of Linux )system. Of the security modules currently available, SELinux is the most comprehensive, and the most well-tested. Basically, load balancing equipment is used for traffic distribution, and only a few ports are opened to the outside world. Therefore, in terms of comprehensive security and complexity, SELinux is not cost-effective. Modify the file to turn off SELinux, as shown below:
<span 1</span> vim /etc/selinux/<span config </span><span 2</span> <span 3</span> <span 注释掉如下两行，在行首添加#注释。 </span><span 4</span> SELINUX=<span enforcing </span><span 5</span> SELINUXTYPE=<span targeted </span><span 6</span> <span 7</span> <span 在后面增加： </span><span 8</span> SELINUX=disabled
’ Restart the system.
<span 1</span> <span 通过yum软件包管理器安装MySql，管理器会自动安装依赖项，遇到询问直接输入y确认，直到显示“Complete！”完成。 </span><span 2</span> <span yum</span> <span install</span> mysql mysql-<span server </span><span 3</span> <span 4</span> <span 启动MySql </span><span 5</span> /etc/init.d/<span mysqld start </span><span 6</span> <span 7</span> <span 设置MySql服务为开机启动 </span><span 8</span> <span chkconfig mysqld on </span><span 9</span> <span 10</span> <span 复制MySql默认配置文件，直接覆盖/etc/my.cnf </span><span 11</span> <span cp</span> /usr/share/mysql/my-medium.cnf /etc/my.cnf
MySql settings:
<span <span 输入如下命令后需要连续输入两次密码确认，有询问输入Y同意即可，成功后显示</span></span><span Thanks for using MySQL!。</span>
<span mysql_secure_installation</span>
After successful setting, you need to restart the MySql service:
<span 1</span> /etc/init.d/<span mysqld stop </span><span 2</span> /etc/init.d/mysqld start
2. Installation and configuration of Apache service
<span 1</span> <span 安装httpd </span><span 2</span> <span yum</span> <span install</span><span httpd </span><span 3</span> <span 4</span> <span 启动Apache服务 </span><span 5</span> /etc/init.d/<span httpd start </span><span 6</span> <span 7</span> <span 编辑apache设置 </span><span 8</span> vim /etc/httpd/conf/<span httpd.conf </span><span 9</span> <span 查找 <span #ServerName www.example.com:80</span></span> <span 10</span> <span 修改成 <span ServerName</span> <span www.XXXX.com:80</span></span> <span 11</span> <span 其中的“www.XXXX.com”自己的域名，没有可设置为localhost，如图 </span><span 12</span> <span 13</span> <span 设置Apache服务开机启动 </span><span 14</span> <span chkconfig httpd on </span><span 15</span> <span 16</span> <span 重启Apache服务 </span><span 17</span> /etc/init.d/httpd restart
3. Install PHP
<span 遇到询问直接输y确认 </span><span yum</span> <span install</span> php
Install PHP plug-in:
<span 插件包括MySql支持等，遇到询问一如既往的y确认~~ </span><span yum</span> <span install</span> php-mysql php-gd libjpeg* php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-bcmath php-mhash libmcrypt
Don’t forget to restart Apache and MySql after the installation is complete:
/etc/init.d/<span mysqld restart </span>/etc/init.d/httpd restart
The installation of this software is over. Next, configure and test.
