Centos7源碼編譯安裝PHP7.2（生產環境）

1. 安裝PHP依賴包，不然在編譯的過程當中可能會出現各類報錯

   # Centos 安裝epel-release源並將系統包更新到最新版本
   $ yum install epel-release-y
   $ yum update
   
   # 安裝PHP依賴組件（包括Nginx依賴）
   $ 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. 建立用戶和組，下載PHP安裝包並解壓

   $ 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. 設置變量並開始源碼編譯

   $ 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：若是報錯請根據報錯狀況安裝依賴包

4. 編譯安裝

   # make 加上 j 參數 指定並行的job數量 提升編譯速度
   $ make -j 4 && make install

5. 完成安裝後配置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. 修改參數

   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是一個輕量級目錄訪問協議，詳情見：https://ldap.com/

      2. 設置OPcache緩存（在php.ini添加下面內容）

         [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. 添加禁用函數列表

         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. 取消如下注釋並修改

         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. 建立php-cgi.sock存放目錄

         $ 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. 建立system系統單元文件php-fpm啓動腳本：

   $ vim /usr/lib/systemd/system/php-fpm.service
   
   # 添加 以下變量內容
   [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：關於systemctl命令能夠參考：Systemd 入門教程

8. 啓動php-fpm服務並加入開機自啓動：

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

9. 以後就能夠使用下面命令開啓關閉php-fpm服務了

   service php-fpm start/restart/stop
