介绍:

久闻php7的速度以及性能那可是比php5系列的任何一版本都要快,具体性能有多好,建议还是先尝试下再说。如果你是升级或新安装,那你首先需要考虑php7和程序是否存在兼容性,如果程序是基于php5开发的,那么就需要考虑php7是否适合你当前的生产环境,今天我就实操并安装用于生产中。

先安装php依赖包,否则在编译安装php7的过程当中会出现各种报错,安装完成后即可进入下一个环节。

安装扩展包并更新系统内核:

$ yum install epel-release -y $ yum update

安装php依赖组件(包含Nginx依赖):

复制代码代码如下:$ 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

创建用户和组,并下载php安装包解压:

$ 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

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-jis-conv –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

若无报错执行下一步安装,如果编译过程中出现错误,根据报错安装依赖包,通常不会出现这种问题。

注意:–enable-gd-jis-conv  此参数会导致Zabbix中文字符乱码,建议取消。

开始安装:

$ make -j 4 && make install

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

修改 php.ini 相关参数:

$ 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”

设置 OPcache 缓存:

[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

设置php安全函数:

$ vim /usr/local/php/etc/php.ini

默认值:

disable_functions =

修改为:

复制代码代码如下: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

或通配:

复制代码代码如下:disable_functions = passthru,exec,system,chroot,chgrp,chown,shell_exec,proc_open,proc_get_status,popen,ini_alter,ini_restore,dl,openlog,syslog,readlink,symlink,popepassthru

配置www.conf

取消以下注释并修改优化其参数:

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

创建php-cgi.sock存放目录

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

配置php-fpm.conf

取下以下注释并填写完整路径:

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

至此php7已经安装完成。

说明:禁用php函数,如果程序需要这些函数,可以取消禁止,新手建议忽略此步骤。

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

启动php-fpm服务并加入开机自启动:

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

PHP整个安装过程已经完成。如果你是按照本文安装未成功的,希望你能留言说明错误原因,我将无偿协助你配置。
