详解Centos7源码编译安装 php7.2之生产篇

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：

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：

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：
