Centos7源码编译安装PHP7.2（生产环境）

1. 安装PHP依赖包，否则在编译的过程中可能会出现各种报错

   # Centos 安装epel-release源并将系统包更新到最新版本
   $ yum install epel-release-y
   $ yum update
   
   # 安装PHP依赖组件（包括Nginx依赖）
   $ yum -y install wget vim pcre pcre-devel openssl openssl-devel libicu-devel gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel ncurses ncurses-devel curl curl-devel krb5-devel libidn libidn-devel openldap openldap-devel nss_ldap jemalloc-devel cmake boost-devel bison automake libevent libevent-devel gd gd-devel libtool* libmcrypt libmcrypt-devel mcrypt mhash libxslt libxslt-devel readline readline-devel gmp gmp-devel libcurl libcurl-devel openjpeg-devel
   

2. 创建用户和组，下载PHP安装包并解压

   $ cd /tmp
   $ groupadd www
   $ useradd -g www www
   $ wget http://am1.php.net/distributions/php-7.2.1.tar.gz
   $ tar xvf php-7.2.1.tar.gz
   $ cd php-7.2.1
   

3. 设置变量并开始源码编译

   $ cp -frp /usr/lib64/libldap* /usr/lib/
   $ ./configure --prefix=/usr/local/php 
   --with-config-file-path=/usr/local/php/etc 
   --enable-fpm 
   --with-fpm-user=www 
   --with-fpm-group=www 
   --enable-mysqlnd 
   --with-mysqli=mysqlnd 
   --with-pdo-mysql=mysqlnd 
   --enable-mysqlnd-compression-support 
   --with-iconv-dir 
   --with-freetype-dir 
   --with-jpeg-dir 
   --with-png-dir 
   --with-zlib 
   --with-libxml-dir 
   --enable-xml 
   --disable-rpath 
   --enable-bcmath 
   --enable-shmop 
   --enable-sysvsem 
   --enable-inline-optimization 
   --with-curl 
   --enable-mbregex 
   --enable-mbstring 
   --enable-intl 
   --with-mcrypt 
   --with-libmbfl 
   --enable-ftp 
   --with-gd 
   --enable-gd-native-ttf 
   --with-openssl 
   --with-mhash 
   --enable-pcntl 
   --enable-sockets 
   --with-xmlrpc 
   --enable-zip 
   --enable-soap 
   --with-gettext 
   --disable-fileinfo 
   --enable-opcache 
   --with-pear 
   --enable-maintainer-zts 
   --with-ldap=shared 
   --without-gdbm 
   

   注：如果报错请根据报错情况安装依赖包

4. 编译安装

   # make 加上 j 参数 指定并行的job数量 提高编译速度
   $ make -j 4 && make install
   

5. 完成安装后配置php.ini文件：

   $ cp php.ini-development /usr/local/php/etc/php.ini
   $ cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
   $ cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
   

6. 修改参数

   1. 修改php.ini

      1. $ vim /usr/local/php/etc/php.ini
         
         expose_php = Off
         short_open_tag = ON
         max_execution_time = 300
         max_input_time = 300
         memory_limit = 128M
         post_max_size = 32M
         date.timezone = Asia/Shanghai
         mbstring.func_overload=2
         extension = "/usr/local/php/lib/php/extensions/no-debug-zts-20160303/ldap.so"
         

         注：ldap是一个轻量级目录访问协议,不安装也可以，详情见：https://ldap.com/

      2. 设置OPcache缓存（在php.ini添加下面内容）

         [opcache]
         zend_extension=/usr/local/php/lib/php/extensions/no-debug-zts-20160303/opcache.so
         opcache.memory_consumption=128
         opcache.interned_strings_buffer=8
         opcache.max_accelerated_files=4000
         opcache.revalidate_freq=60
         opcache.fast_shutdown=1
         opcache.enable_cli=1
         

      3. 添加禁用函数列表

         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
         

   2. 配置www.conf

      1. 取消以下注释并修改

         listen = /var/run/www/php-cgi.sock
         listen.owner = www
         listen.group = www
         listen.mode = 0660
         listen.allowed_clients = 127.0.0.1
         pm = dynamic
         listen.backlog = -1
         pm.max_children = 180
         pm.start_servers = 50
         pm.min_spare_servers = 50
         pm.max_spare_servers = 180
         request_terminate_timeout = 120
         request_slowlog_timeout = 50
         slowlog = var/log/slow.log
         

      2. 创建php-cgi.sock存放目录

         $ mkdir /var/run/www/
         $ chown -R www:www /var/run/www
         

      3. 配置php-fpm.conf

         pid = /usr/local/php/var/run/php-fpm.pid
         

7. 创建system系统单元文件php-fpm启动脚本：

   $ vim /usr/lib/systemd/system/php-fpm.service
   
   # 添加 如下变量内容
   [Unit]
   Description=The PHP FastCGI Process Manager
   After=syslog.target network.target
    
   [Service]
   Type=simple
   PIDFile=/usr/local/php/var/run/php-fpm.pid
   ExecStart=/usr/local/php/sbin/php-fpm --nodaemonize --fpm-config /usr/local/php/etc/php-fpm.conf
   ExecReload=/bin/kill -USR2 $MAINPID
    
   [Install]
   WantedBy=multi-user.target
   

   注：关于systemctl命令可以参考：Systemd 入门教程

8. 启动php-fpm服务并加入开机自启动：

   $ systemctl enable php-fpm.service
   $ systemctl restart php-fpm.service
   

9. 之后就可以使用下面命令开启关闭php-fpm服务了

   service php-fpm start/restart/stop
