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，详情见：

    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
