XCache
快速而且稳定的PHP opcode缓存，经过严格测试且被大量用于生产环境。
项目地址：http://xcache.lighttpd.net/,收录EPEL源
实现XCache源码编译
（1）官网下载xcache包，传到linux中并解压
[root@centos777~]#rz [root@centos777~]#tar xvf xcache-3.2.0.tar.gz
（2）切换到解压的目录中开始编译安装开发环境包
[root@centos777xcache-3.2.0]#cd xcache-3.2.0/ [root@centos777xcache-3.2.0]#yum groupinstall "development tools" -y
（3）查看编译INSTALL帮助文档
（4）安装php包及依赖的php-devel开发包
[root@centos777xcache-3.2.0]#yum install php -y [root@centos777xcache-3.2.0]#yum install php-devel -y
（5）再执行一次phpize工具，生成configure
[root@centos777xcache-3.2.0]#phpize Configuring for: PHP Api Version: 20100412 Zend Module Api No: 20100525 Zend Extension Api No: 220100525
（6）开始./configure、make && make install
[root@centos777xcache-3.2.0]#./configure --prefix=/app/xcache --enable-xcache [root@centos777xcache-3.2.0]#make && make install
（7）将xcache.ini配置文件复制到/etc/php.ini目录下并重启httpd服务
[root@centos777xcache-3.2.0]#cp xcache.ini /etc/php.d/ [root@centos777xcache-3.2.0]#systemctl restart httpd

A主机：192.168.34.100 编译httpd
B主机：192.168.34.101 安装二进制mariadb
LAMP源码编译
A主机进行源码编译httpd服务
（1）解压httpd、arp、apr-util包
[root@centos7src]#mkdir src [root@centos7src]#cd src [root@centos7src]#tar xf httpd-2.4.39.tar.bz2 [root@centos7src]#tar xf apr-util-1.6.1.tar.bz2 [root@centos7src]#tar xf apr-1.6.5.tar.bz2 [root@centos7src]#cp -r apr-1.6.5 httpd-2.4.39/srclib/apr [root@centos7src]#cp -r apr-util-1.6.1 httpd-2.4.39/srclib/apr-util
（2）开始安装httpd开发包组及依赖包
[root@centos7httpd-2.4.39]#yum groupinstall "development tools" -y [root@centos7httpd-2.4.39]#yum install pcre-devel openssl-devel expat-devel -y
（3）切换到httpd目录下，编译httpd
[root@centos7~]#cd src/httpd-2.4.39/ ./configure \ --prefix=/app/httpd24 \ --enable-so \ --enable-ssl \ --enable-cgi \ --enable-rewrite \ --with-zlib \ --with-pcre \ --with-included-apr \ --enable-modules=most \ --enable-mpms-shared=all \ --with-mpm=prefork
（4）开始多线程编译安装httpd
[root@centos7httpd-2.4.39]#make -j 4 && make install
（5）指定PATH变量路径并生效
[root@centos7~]#echo 'PATH=/app/httpd24/bin:$PATH' > /etc/profile.d/lamp.sh [root@centos7~]#. /etc/profile.d/lamp.sh
（6）创建apache账号并在配置文件中修改启动账号
[root@centos7src]#useradd -s -r /sbin/nologin apache [root@centos7src]#vim /app/httpd24/conf/httpd.conf User apache Group apache <IfModule dir_module> DirectoryIndex index.php index.html 默认只支持index.html页面，可以添加一个支持index.php页面选项 </IfModule> 在最后一行写上以下内容，为了支持php程序 AddType application/x-httpd-php .php AddType application/x-httpd-php-source .phps
启动fcgi和proxy代理服务，取消两行的注释，并制定应用程序路径：
LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so LoadModule proxy_module modules/mod_proxy.so ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/app/httpd24/htdocs/$1 开启FCGI反向代理,//前面的/相对于后面的/app/httpd24/htdocs而言，后面的$1是指前面的/(.*\.php)
修改apache登陆账号
支持一个index.php格式的页面
写到最后一行，使httpd服务支持php，并指定应用程序路径
启动代理，取消注释的两行
注意：此时由于还没有编译安装php包，apache暂时无法启动，等php包安装完一并启动
B主机进行mariadb二进制安装
官网下载地址：https://downloads.mariadb.org/mariadb/10.2.29/
（1）将mariadb包传到linux中，并解压到指定的文件中
rz [root@centos7~]#tar xvf mariadb-10.3.20.tar.gz -C /usr/local/
（2）创建用户账号、修改权限及创建软链接
[root@centos7local]#cd /usr/local root@centos7local]#useradd -s /sbin/nologin -r mysql -d /data/mysql [root@centos7local]#ls bin etc games include lib lib64 libexec mariadb-10.3.20 sbin share src [root@centos7local]#chown -R root.root mariadb-10.3.20/ [root@centos7local]#ln -s mariadb-10.3.20/ mysql [root@centos7local]#ll mysql lrwxrwxrwx 1 root root 16 Nov 30 21:16 mysql -> mariadb-10.3.20/
（3）执行脚本指定数据库目录文件
[root@centos7mysql]#mkdir /data/mysql [root@centos7mysql]#cd /usr/local/mysql [root@centos7mysql]#scripts/mysql_install_db --user=mysql --datadir=/data/mysql
（4）创建配置文件
[root@centos7mysql]#mkdir /etc/mysql [root@centos7local]#cd mariadb-10.2.29-linux-x86_64/ [root@centos7mysql]#cp support-files/my-huge.cnf /etc/mysql/my.cnf
修改my.conf配置文件
[root@centos7mysql]#vim /etc/mysql/my.cnf [mysqld] datadir=/data/mysql
（5）复制mysqld服务启动脚本，并加入到服务中
[root@centos7mysql]#cp support-files/mysql.server /etc/init.d/mysqld 将启动服务复制到etc/init.d目录下，起名叫mysqld
[root@centos7mysql]#chkconfig --add mysqld
[root@centos7mysql]#chkconfig --list mysqld
Note: This output shows SysV services only and does not include native
systemd services. SysV configuration data might be overridden by native
systemd configuration.
If you want to list systemd services use 'systemctl list-unit-files'.
To see services enabled on particular target use
'systemctl list-dependencies [target]'.
mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off
（6）启动mariadb服务并制定PATH变量路径
[root@centos7mysql]#service mysqld start [root@centos7mysql]#echo 'PATH=/usr/local/mysql/bin:$PATH' > /etc/profile.d/mysql.sh [root@centos7mysql]#. /etc/profile.d/mysql.sh
（7）创建一个数据库和用户名
[root@centos7mysql]#mysql Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 10 Server version: 10.2.29-MariaDB-log MariaDB Server Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. MariaDB [(none)]> create database wpdb; 创建wpdb数据库 Query OK, 1 row affected (0.01 sec) MariaDB [(none)]> grant all on wpdb.* to wpuser@'192.168.34.%' identified by 'centos'; 创建用户名 Query OK, 0 rows affected (0.00 sec)
在A主机源码编译php
（1）先安装php依赖相关包，并解压php包
[root@centos7~]#cd src [root@centos7src]#ls apr-1.6.5 apr-1.6.5.tar.bz2 apr-util-1.6.1 apr-util-1.6.1.tar.bz2 httpd-2.4.39 httpd-2.4.39.tar.bz2 php-7.1.18.tar.bz2 [root@centos7src]#yum install libxml2-devel bzip2-devel libmcrypt-devel -y [root@centos7src]#tar xfv php-7.1.18.tar.bz2
（2）切换到php解压后包目录下，并进行./configure安装，可以查看./configure --help帮助文档
[root@centos7src]#cd php-7.1.18/ ./configure --prefix=/app/php \ --enable-mysqlnd \ --with-mysqli=mysqlnd \ --with-openssl \ --with-pdo-mysql=mysqlnd \ --enable-mbstring \ --with-freetype-dir \ --with-jpeg-dir \ --with-png-dir \ --with-zlib \ --with-libxml-dir=/usr \ --enable-xml \ --enable-sockets \ --enable-fpm \ --with-config-file-path=/etc \ --with-config-file-scan-dir=/etc/php.d \ --enable-maintainer-zts \ --disable-fileinfo
（3）开始多线程编译安装php
[root@centos7httpd-2.4.39]#make -j 4 && make install
（4）在php目录下，复制一个php的配置文件到/etc/目录下
[root@centos7php-7.1.18]#cp php.ini-production /etc/php.ini
（5）在php目录下复制一个启动脚本到/etc/init.d/目录下，并加上执行权限
[root@centos7php-7.1.18]#cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm 启动脚本名 [root@centos7php-7.1.18]#chmod +x /etc/init.d/php-fpm [root@centos7php-7.1.18]#chkconfig --add php-fpm 将php-fpm加入到启动服务中
（6）解压wordpress包，并将包移动到htdocs目录下
[root@centos7src]#tar xvf wordpress-4.9.4-zh_CN.tar.gz [root@centos7src]#cd wordpress/ [root@centos7wordpress]#ls index.php wp-activate.php wp-comments-post.php wp-cron.php wp-load.php wp-settings.php xmlrpc.php license.txt wp-admin wp-config-sample.php wp-includes wp-login.php wp-signup.php readme.html wp-blog-header.php wp-content wp-links-opml.php wp-mail.php wp-trackback.php [root@centos7wordpress]#mv * /app/httpd24/htdocs/ 将wordpress目录下的文件全部移动到htdocs目录下
（7）在/app/httpd24/htdocs目录下修改配置文件的名称并修改配置文件
[root@centos7wordpress]#cd /app/httpd24/htdocs [root@centos7htdocs]#ls index.html readme.html wp-blog-header.php wp-content wp-links-opml.php wp-mail.php wp-trackback.php index.php wp-activate.php wp-comments-post.php wp-cron.php wp-load.php wp-settings.php xmlrpc.php license.txt wp-admin wp-config-sample.php wp-includes wp-login.php wp-signup.php [root@centos7htdocs]#mv wp-config-sample.php wp-config.php [root@centos7htdocs]#vim wp-config.php
（8）修改配置文件名称
[root@centos7~]#cd /app/php/etc [root@centos7etc]#cp php-fpm.conf.default php-fpm.conf [root@centos7etc]#cd php-fpm.d/ [root@centos7php-fpm.d]#cp www.conf.default www.conf
（9）启动php服务，此时所有的编译完成，可以在网页上查看wordpress搭建后的效果
[root@centos7php-fpm.d]#service php-fpm start [root@centos7php-fpm.d]#apachectl start
查看网页上的wordpress界面，此时已经完成了搭建效果：
最后：我们来测试一下编译后最新版本的php、httpd、mariadb搭建的wordpress运行速度
[root@centos777.ssh]#ab -c 10 -n 200 http://192.168.34.100/ ab命令测试
