安装准备
yum install \ vim \ gcc \ gcc-c++ \ wget \ make \ re2c \ libtool \ automake \ autoconf \ curl-devel \ libpng-devel \ libxml2-devel \ libxslt-devel \ openssl-devel \ freetype-devel \ bzip2-devel \ libicu-devel \ libuuid-devel \ libmcrypt-devel \ postgresql-devel \ -y -
安装php
cd /root wget http://cn2.php.net/distributions/php-7.2.6.tar.gz tar -zxvf php-7.2.6.tar.gz cd php-7.2.6 ./configure \ --prefix=/usr/local/php \ --enable-mysqlnd \ --with-openssl \ --enable-fpm # 如果在/usr/local/apache/路径下安装了apache并且想让php运行在apache下,需要加上: # --with-apxs2=/usr/local/apache/bin/apxs # 或 --with-apxs2=/usr/local/apache/bin/apxs2 # apxs在有些apache发行版中已经改名为apxs2 make make install # 如果在/usr/local/apache/路径下安装了apache并且想让php运行在apache下,apache不需要重新编译 # 这时候/usr/local/apache/modules/下多了一个libphp7.so文件 # 编辑/etc/httpd/httpd.conf添加如下行: LoadModule php7_module modules/libphp7.so DocumentRoot "/www" <FilesMatch \.php$> SetHandler application/x-httpd-php </FilesMatch> # 编辑/www/index.php添加如下行: <?php phpinfo(); # 重启apache # 访问http://xxx.xxx.xxx.xxx/index.php -
生成php.ini、php-fpm.conf、www.conf
# 检查php.ini是否正确放置（只需要第一行不为none） /usr/local/php/bin/php --ini 部署环境执行： cp ./php.ini-production /usr/local/php/lib/php.ini 开发环境执行： cp ./php.ini-development /usr/local/php/lib/php.ini # 拷贝php-fpm.conf cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf # PHP7才执行(PHP5中，www.conf的配置项在php-fpm.conf) cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf -
php.ini常规配置
# 下载cacert.pem cd /usr/local/php/lib wget https://curl.haxx.se/ca/cacert.pem vim /usr/local/php/lib/php.ini ;php版本信息隐藏 expose_php=Off ;防止显示php错误输出,Off: 不输出但存入日志 display_errors=Off ;防止用户将可执行文件伪装成静态文件(如图片、文档)上传后，通过访问WEB页面执行该文件 cgi.fix_pathinfo=0 ;允许上传单个文件最大20M upload_max_filesize=20M ;session.name如果自己开发程序可以改,但如果是部署已有项目,修改后可能导致session相关功能异常 session.name=self_key ;每请求10次session的key,检查1次key是否需要过期删除 session.gc_probability=1 session.gc_divisor=1000 ;设置session默认5分钟(300秒)过期 session.gc_maxlifetime=1440 ;时区中国上海 date.timezone=Asia/Shanghai ;curl、openssl配置cacert.pem curl.cainfo=/usr/local/php/lib/cacert.pem openssl.cafile=/usr/local/php/lib/cacert.pem ESC :wq -
配置php-fpm.conf
vim /usr/local/php/etc/php-fpm.conf pid=run/php-fpm.pid error_log=log/php-fpm.log # 如开启该配置↓,下一步不可跳过 rlimit_files=51200 ESC :wq -
调整最大文件打开数(数值仅供参考,如上一步骤未配置rlimit_files,本步可跳过)
# 在文件末尾添加 vim /etc/security/limits.conf * soft nproc 65535 * hard nproc 65535 * soft nofile 65535 * hard nofile 65535 ESC :wq -
配置www.conf(内存较大、较小两套方案)
vim /usr/local/php/etc/php-fpm.d/www.conf user=www group=www # 静态分配子进程(内存1G,计划为php分配 640M 内存) pm=static pm.max_children=20 pm.start_servers=15 pm.min_spare_servers=10 pm.max_spare_servers=20 pm.process_idle_timeout=10s pm.max_requests=500 slowlog=log/$pool.log.slow php_admin_value[memory_limit]=32M # 动态分配子进程(内存1G,计划为php分配 640M 内存) pm=dynamic pm.max_children=20 pm.start_servers=15 pm.min_spare_servers=10 pm.max_spare_servers=20 pm.process_idle_timeout=10s pm.max_requests=500 slowlog=log/$pool.log.slow php_admin_value[memory_limit]=32M ESC :wq # 以下配置仅供了解,不建议这样使用 listen=127.0.0.1:9000 若改为 listen=/usr/local/php/var/run/php-fpm.sock 则nginx配置 fastcgi_pass 127.0.0.1:9000; 要改为 fastcgi_pass unix:/usr/local/php/var/run/php-fpm.sock; -
将php加入环境变量
vim /etc/profile export PATH=$PATH:/usr/local/php/bin ESC :wq source /etc/profile -
安装composer
# 下载(需要先安装zlib扩展) cd /usr/local/php/bin curl -sS https://getcomposer.org/installer | /usr/local/php/bin/php mv ./composer.phar ./composer composer -V -
启动php并设置开机启动
# 添加www用户 useradd www mkdir /www chown -R www:www /www chown -R www:www /usr/local/php # 进入单元文件目录 cd /etc/systemd/system vim php7.service [Unit] Description=Start php7 on boot. After=network.target [Service] User=root Group=root Type=forking ExecStart=/usr/local/php/sbin/php-fpm ExecReload=/bin/kill -USR2 `cat /usr/local/php/var/run/php-fpm.pid` ExecStop=/bin/kill -INT `cat /usr/local/php/var/run/php-fpm.pid` PrivateTmp=true [Install] WantedBy=multi-user.target ESC :wq # 修改文件权限为只有root用户可以编辑该文件 chown -R root:root /etc/systemd/system/php7.service chmod -R 644 /etc/systemd/system/php7.service # 更新systemd systemctl daemon-reload systemctl enable php7 systemctl start php7 -
查看运行情况
# 查看主进程、子进程 ps aux | grep php-fpm # 查看pid文件(存在即成功) ll /usr/local/php/var/run/ -
php进程操作
# 平滑关闭 kill -INT `cat /usr/local/php/var/run/php-fpm.pid` # 平滑重启 kill -USR2 `cat /usr/local/php/var/run/php-fpm.pid` -
