• CentOS 6.5系统安装配置LAMP(Apache+PHP5+MySQL)服务器环境


    准备篇:

    1、配置防火墙,开启80端口、3306端口
    vi /etc/sysconfig/iptables
    -A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT #允许80端口通过防火墙
    -A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT #允许3306端口通过防火墙

    备注:很多网友把这两条规则添加到防火墙配置的最后一行,导致防火墙启动失败,

    正确的应该是添加到默认的22端口这条规则的下面

    如下所示:

    -A FORWARD -j REJECT --reject-with icmp-host-prohibited
    COMMIT

    /etc/init.d/iptables restart #重启防火墙使配置生效

    2、关闭SELINUX
    vi /etc/selinux/config
    #SELINUX=enforcing #注释掉
    #SELINUXTYPE=targeted #注释掉
    SELINUX=disabled #增加
    :wq!#保存退出
    shutdown -r now#重启系统

    安装篇:

    一、安装Apache
    yum install httpd #根据提示,输入Y安装即可成功安装
    /etc/init.d/httpd start#启动Apache
    备注:Apache启动之后会提示错误:
    正在启动 httpd:httpd: Could not reliably determine the server's fully qualif domain name, using ::1 for ServerName
    解决办法:
    vi /etc/httpd/conf/httpd.conf #编辑
    找到 #ServerName www.example.com:80
    修改为 ServerName www.jbaobao.net:80 #这里设置为你自己的域名,如果没有域名,可以设置为localhost
    :wq! #保存退出
    chkconfig httpd on #设为开机启动
    /etc/init.d/httpd restart #重启Apache

    二、安装MySQL

    1、安装MySQL
    yum install mysql mysql-server #询问是否要安装,输入Y即可自动安装,直到安装完成
    /etc/init.d/mysqld start #启动MySQL
    chkconfig mysqld on #设为开机启动
    cp /usr/share/mysql/my-medium.cnf /etc/my.cnf #拷贝配置文件(注意:如果/etc目录下面默认有一个my.cnf,直接覆盖即可)

    2、为root账户设置密码
    mysql_secure_installation
    回车,根据提示输入Y
    输入2次密码,回车
    根据提示一路输入Y
    最后出现:Thanks for using MySQL!
    MySql密码设置完成,重新启动 MySQL:
    /etc/init.d/mysqld restart #重启
    /etc/init.d/mysqld stop #停止
    /etc/init.d/mysqld start #启动

    Enter current password for root (enter for none):<–初次运行直接回车
    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] <– 是否设置root用户密码,输入y并回车或直接回车
    New password: <– 设置root用户的密码
    Re-enter new password: <– 再输入一次你设置的密码
    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] <– 是否删除匿名用户,生产环境建议删除,所以直接回车
    … 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] <–是否禁止root远程登录,根据自己的需求选择Y/n并回车,建议禁止
    … 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] <– 是否删除test数据库,直接回车
    - 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] <– 是否重新加载权限表,直接回车
    … 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!

    三、安装PHP5

    1、安装PHP5

    系统运维 温馨提醒:qihang01原创内容版权所有,转载请注明出处及原文链接
    yum install php #根据提示输入Y直到安装完成

    2、安装PHP组件,使 PHP5 支持 MySQL
    yum install 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 #这里选择以上安装包进行安装,根据提示输入Y回车
    /etc/init.d/mysqld restart #重启MySql
    /etc/init.d/httpd restart #重启Apche

    配置篇

    一、Apache配置
    vi /etc/httpd/conf/httpd.conf #编辑文件
    ServerTokens OS  #在44行 修改为:ServerTokens Prod (在出现错误页的时候不显示服务器操作系统的名称)
    ServerSignature On  #在536行 修改为:ServerSignature Off (在错误页中不显示Apache的版本)
    Options Indexes FollowSymLinks  #在331行 修改为:Options Includes ExecCGI FollowSymLinks(允许服务器执行CGI及SSI,禁止列出目录)
    #AddHandler cgi-script .cgi #在796行 修改为:AddHandler cgi-script .cgi .pl (允许扩展名为.pl的CGI脚本运行)
    AllowOverride None  #在338行 修改为:AllowOverride All (允许.htaccess)
    AddDefaultCharset UTF-8 #在759行 修改为:AddDefaultCharset GB2312 (添加GB2312为默认编码)
    Options Indexes MultiViews FollowSymLinks #在554行 修改为 Options MultiViews FollowSymLinks(不在浏览器上显示树状目录结构)
    DirectoryIndex index.html index.html.var #在402行 修改为:DirectoryIndex index.html index.htm Default.html Default.htm index.php Default.php index.html.var (设置默认首页文件,增加index.php)
    KeepAlive Off #在76行 修改为:KeepAlive On (允许程序性联机)
    MaxKeepAliveRequests 100 #在83行 修改为:MaxKeepAliveRequests 1000 (增加同时连接数)
    :wq! #保存退出
    /etc/init.d/httpd restart#重启
    系统运维 温馨提醒:qihang01原创内容版权所有,转载请注明出处及原文链接
    rm -f /etc/httpd/conf.d/welcome.conf /var/www/error/noindex.html #删除默认测试页

    二、php配置
    vi /etc/php.ini #编辑
    date.timezone = PRC #在946行 把前面的分号去掉,改为date.timezone = PRC
    disable_functions = passthru,exec,system,chroot,scandir,chgrp,chown,shell_exec,proc_open,proc_get_status,ini_alter,ini_alter,ini_restore,dl,openlog,syslog,readlink,symlink,popepassthru,stream_socket_server,escapeshellcmd,dll,popen,disk_free_space,checkdnsrr,checkdnsrr,getservbyname,getservbyport,disk_total_space,posix_ctermid,posix_get_last_error,posix_getcwd, posix_getegid,posix_geteuid,posix_getgid, posix_getgrgid,posix_getgrnam,posix_getgroups,posix_getlogin,posix_getpgid,posix_getpgrp,posix_getpid, posix_getppid,posix_getpwnam,posix_getpwuid, posix_getrlimit, posix_getsid,posix_getuid,posix_isatty, posix_kill,posix_mkfifo,posix_setegid,posix_seteuid,posix_setgid, posix_setpgid,posix_setsid,posix_setuid,posix_strerror,posix_times,posix_ttyname,posix_uname
    #在386行 列出PHP可以禁用的函数,如果某些程序需要用到这个函数,可以删除,取消禁用。
    expose_php = Off #在432行 禁止显示php版本的信息
    magic_quotes_gpc = On #在745行 打开magic_quotes_gpc来防止SQL注入
    short_open_tag = ON #在229行支持php短标签
    open_basedir = .:/tmp/ #在380行 设置表示允许访问当前目录(即PHP脚本文件所在之目录)和/tmp/目录,可以防止php木马跨站,如果改了之后安装程序有问题,可以注销此行,或者直接写上程序的目录/data/www.osyunwei.com/:/tmp/
    :wq! #保存退出
    /etc/init.d/mysqld restart #重启MySql
    /etc/init.d/httpd restart #重启Apche

    测试篇
    cd /var/www/html
    vi index.php #编辑输入下面内容
    <?php
    phpinfo();
    ?>
    :wq! #保存退出
    在客户端浏览器输入服务器IP地址,可以看到相关的配置信息!

    phpMyAdmin常见问题
    1. phpmyadmin提示未开启php-mcrypt,这是因为没有安装php-mrcrpt扩展。在官方源没有php-mrcrpt扩展,请安装epel源后再yum install php-mcrypt

    2. phpmyadmin无法访问

    phpmyadmin默认只能使用http://localhost/phpmyadmin来访问,可以修改/etc/httpd/conf.d/phpmyadmin.conf中对应部分为
    <Directory "/usr/share/phpmyadmin">
    Order Deny,Allow
    # Deny from all
    Allow from All
    </Directory>
    不过强烈不支持这么做的,把phpmyadmin暴露了不安全

    注意:
    apache解析php,修改httpd.conf文件,添加
    Addtype application/x-httpd-php .php .phtml
    Addtype application/x-httpd-php-source .phps

    myql可以远程登录
    设置mysql密码
    mysql>; USE mysql;
    mysql>; UPDATE user SET Password=PASSWORD('newpassword') WHERE user='root';
    mysql>; FLUSH PRIVILEGES;
    1.2.3 允许远程登录
    mysql -u root -p
    Enter Password: <your new password>
    mysql>GRANT ALL PRIVILEGES ON *.* TO '用户名'@'%' IDENTIFIED BY '密码' WITH GRANT OPTION;
    完成后就能用mysql-front远程管理mysql了。
    设为开机启动
    chkconfig mysqld on
