CentOS 7.2 amp + xcache, rpm包,php-fpm

前端之家收集整理的这篇文章主要介绍了CentOS 7.2 amp + xcache, rpm包,php-fpm前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

1、实验需求: 1)CentOS 7,amp + xcache, rpm包,PHP-fpm; a) httpd,PHP,mariadb分别部署在一个单独的主机上; b) 一个虚拟主机提供wordpress,另一个虚拟主机提供;PHPMyAdmin c) 为PHPMyAdmim提供https服务; 2、实验环境: 1)服务器环境 Linux服务器操作系统版本:CentOS release 6.7 (Final) http) IP: 172.16.66.60 PHP-fpm) IP:172.16.66.70 mariadb) IP:172.16.66.70 2)测试环境 WIN7系统客户机):IP:172.16.66.1003、实验前提: 1)关闭防火墙和SELinux ~]# service iptables stop ~]# sed -i s/SELINUX=enforcing/SELINUX=disabled/g /etc/selinux/config 4、实验过程:第一部分: 部署主机IP: 172.16.66.60 1 基本设置 1.1 设置 httpd 主机名 HOSTNAMEecho "HOSTNAME=www1" >> /etc/sysconfig/network 1.2 更新 HOSTS 配置文件 /etc/hostsvim /etc/hosts172.16.66.60 www1 1.3 修改 DNS 解析设置vim /etc/resolv.conf2 安装 LAMP 2.2 安装并配置 Apache 网络服务器yum install httpd 2.3备份配置文件(建议对于所有的配置文件,做任何更改前都先备份一份,以便应对未知错误)mkdir ~/confbakcp -R /etc/httpd ~/confbak其中 ~ 表示当前登录用户用户文件夹;-R 参数表示递归到所有子目录。 2.4配置虚拟主机(/etc/httpd/conf.d/www1.conf )vim /etc/httpd/conf.d/www1.conf 主机www1 [root@www1 conf.d]# cat www1.conf <VirtualHost *:80> ServerName www1# ServerAlias www DocumentRoot /data/vhosts/www1 #注意这行末尾不要带 / ProxyRequests Off DirectoryIndex index.PHP ProxyPassMatch ^/(.*\.PHP)$ fcgi://172.16.66.70:9000/data/vhosts/www1/$1<Directory "/data/vhosts/www1"> Options None AllowOverride None Require all granted</Directory> ErrorLog logs/www1-error_log CustomLog logs/www1-access_log combien #ServerSignature Off</VirtualHost> 2.5配置虚拟主机(/etc/httpd/conf.d/www2.conf )vim /etc/httpd/conf.d/www2.conf 主机 www2[root@www1 conf.d]# cat www2.conf <VirtualHost *:80> ServerName www2 DocumentRoot /data/vhosts/www2 ProxyRequests Off DirectoryIndex index.PHP ProxyPassMatch ^/(.*\.PHP)$ fcgi://172.16.66.70:9000/data/vhosts/www2/$1<Directory "/data/vhosts/www2"> Options None AllowOverride None Require all granted</Directory> ErrorLog logs/www2-error_log CustomLog logs/www2-access_log combien #ServerSignature Off</VirtualHost> 2.6为虚拟主机创建(网站目录)主机 1 的mkdir /data/vhosts/www1/ -p主机 2 的mkdir /data/vhosts/www2/ -p 2.7为了能够在系统启动时自动运行 Apache 服务器,需要运行下面的指令:systemctl enable httpd 输出类似于ln -s '/usr/lib/systemd/system/httpd.service' '/etc/systemd/system/multi-user.target.wants/httpd.service' 2.8启动 Apache 服务systemctl start httpd 2.9提示Apache已启动重启加载systemctl reload httpd现在需要将 http 服务加入防火墙以允许外部访问(也就是将 HTTP 默认使用的端口 80 加入到防火墙允许列表里),firewall-cmd --add-service=http --permanent�permanent 参数表示这是一条永久防火墙规则,如果不加这个参数则重启系统后就没有这条规则了。重启 Firewalld 使该规则生效systemctl restart firewalld如果防火墙默认没有启动,则上述指令会提示错误,“FirewallD is not running”。那么先启用防火墙服务。systemctl enable firewalld && systemctl start firewalld如果要查看加入后的防火墙规则,使用如下命令。firewall-cmd --list-all 总结一下关键点,httpd 服务默认配置文件: 默认配置文件: /etc/httpd/conf/httpd.conf 加载模块的配置文件: /etc/httpd/conf.modules.d/ directory (e.g. PHP) 选择 MPMs (处理模式) [worker,prefork (默认是这个)] 和 event: /etc/httpd/conf.modules.d/00-mpm.conf 默认端口: 80 和 443 (SSL) 默认日志: /var/log/httpd/{access_log,error_log}还可以直接用 apachectl 来控制 Apache 服务执行一些操作,比如优雅地重新加载配置,apachectl graceful“优雅地”的意思是不中断客户的访问的情况下逐渐地将所有 httpd 进程更新为使用新配置的新进程。详情需要查看其简单的帮助文件,apachectl -h其它重要的防火墙 Firewalld 选项有,# firewall-cmd --state# firewall-cmd --list-all# firewall-cmd --list-interfaces# firewall-cmd --get-service# firewall-cmd --query-service service_name# firewall-cmd --add-port=8080/tcp第二部分:部署PHP-fpm主机IP: 172.16.66.701安装和配置 PHP-fpm 1.1安装 PHP-fpm yum install PHP-fpm MysqL-server -y 1.2备份配置文件 /etc/PHP.ini,还有 PHP.conf 以及 00-PHP.conf,cp /etc/PHP.ini ~/confbak/PHP.ini.bakcp /etc/httpd/conf.d/PHP.conf ~/confbak/httpd/conf.d/PHP.conf.bakcp /etc/httpd/conf.modules.d/00-PHP.conf ~/confbak/httpd/conf.modules.d/00-PHP.conf.bak 1.3并确保 /etc/PHP.ini 中有下面的语句(不同的就修改,没有的就添加,某些数值可以后再调整,这是针对一个简单的运行 wordpress 的服务器的配置):error_reporting = E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERRORdisplay_errors = Offlog_errors = Onmax_execution_time = 300memory_limit = 32M2安装和配置PHP-MysqL (为了在 PHP 中使用 MysqL,还需要安装这个 PHP-MysqL 包): 2.1安装PHP-MysqLyum install PHP-MysqL -y第三部分:部署mariadb主机IP: 172.16.66.80 1安装和配置 Mariadb 数据库服务MariaDB 是在 MysqL 基础上重建的一个数据库软件,各 Linux 发行版都陆陆续续从 MysqL 切换到了 MariaDB。CentOS 从 7 开始默认使用 MariaDB。 1.1安装yum install mariadb-server mariadb 1.2 加入随系统启动systemctl enable mariadb 1.3 启动 mariadb 守护进程(MysqLd)其默认用户名还是 MysqLsystemctl start mariadb 1.4以查看内存占用情况。top -u MysqL 1.5停止/重启或停用 mariadb 服务的一些指令:停止sudo systemctl stop mariad重启sudo systemctl restart mariadb禁用sudo systemctl disable mariadb检查sudo systemctl is-active mariadb2安全配置 MariaDB使用 MariaDB 内建的安全配置脚本进行配置MysqL_secure_installation这里需要配置 MysqL用户和密码、清除其他用户、清除不需要的数据库等。输出类似于下面的执行过程,其中需要我们从键盘输入的内容用蓝色注释出来了:/usr/bin/MysqL_secure_installation/usr/bin/MysqL_secure_installation: line 379: find_MysqL_client: command not foundNOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDBSERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!In order to log into MariaDB to secure it,we'll need the currentpassword for the root user. If you've just installed MariaDB,andyou 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):这里直接回车,这里可不是 Linux root 用户,而是 MariaDB 数据库的 root 用户OK,successfully used password,moving on...Setting the root password ensures that nobody can log into the MariaDBroot user without the proper authorisation.Set root password? [Y/n] yNew password:输入你的数据库root用户密码Re-enter new password:再输入一遍Password updated successfully!Reloading privilege tables..... Success!By default,a MariaDB installation has an anonymous user,allowing anyoneto log into MariaDB without having to have a user account created forthem. This is intended only for testing,and to make the installationgo a bit smoother. You should remove them before moving into aproduction environment.Remove anonymous users? [Y/n] y --删除匿名用户?... Success!Normally,root should only be allowed to connect from 'localhost'. Thisensures that someone cannot guess at the root password from the network.Disallow root login remotely? [Y/n] y --不允许远程root登录吗?... Success!By default,MariaDB comes with a database named 'test' that anyone canaccess. This is also intended only for testing,and should be removedbefore moving into a production environment.Remove test database and access to it? [Y/n] y --删除测试数据库和访问吗?- Dropping test database...... Success!- Removing privileges on test database...... Success!Reloading the privilege tables will ensure that all changes made so farwill take effect immediately.Reload privilege tables now? [Y/n] y --现在重新加载权限表吗?... Success!Cleaning up...All done! If you've completed all of the above steps,your MariaDBinstallation should now be secure.Thanks for using MariaDB! 2.1输入密码后回车,下面是输出示例,可以看到命令提示符变为 MariaDB [(none)]>MysqL -u root -pEnter password:Welcome to the MariaDB monitor.
