When you running a highload website with PHP-FPM<\/span> via FastCGI, the following tips may be 1. Compile PHP\u2019s modules as less as possible, 2. Increas PHP FastCGI child number to 100 3. Using SOCKET PHP FastCGI, and put into 4. Increase Linux \u201cmax open files\u201d, using the 5. Increase PHP-FPM<\/span> \n6. Using PHP code accelerator, e.g \u4e8eNginx\u5bf9\u9ad8\u5e76\u53d1\u7684\u4f18\u826f\u6027\u80fd\uff0c\u6545\u914d\u4e86\u4e2aNginx+php-fpm\u6765\u8dd1\u5728\u7ebf\u4ee3\u7406\u7a0b\u5e8f\uff0c\u662f\u6309\u7167\u5f20\u5bb4\u6587\u7ae0\u914d\u7684\uff0c\u521a\u914d\u7f6e...<\/p>\n","protected":false},"author":3,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[15329],"tags":[],"class_list":["post-689","post","type-post","status-publish","format-standard","hentry","category-nginx"],"_links":{"self":[{"href":"https:\/\/lnmp.ivan.xin\/index.php?rest_route=\/wp\/v2\/posts\/689","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lnmp.ivan.xin\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lnmp.ivan.xin\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lnmp.ivan.xin\/index.php?rest_route=\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/lnmp.ivan.xin\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=689"}],"version-history":[{"count":1,"href":"https:\/\/lnmp.ivan.xin\/index.php?rest_route=\/wp\/v2\/posts\/689\/revisions"}],"predecessor-version":[{"id":690,"href":"https:\/\/lnmp.ivan.xin\/index.php?rest_route=\/wp\/v2\/posts\/689\/revisions\/690"}],"wp:attachment":[{"href":"https:\/\/lnmp.ivan.xin\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=689"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lnmp.ivan.xin\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=689"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lnmp.ivan.xin\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=689"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
