基礎(chǔ)
筆記
- 選擇安裝JeMalloc或者TCMalloc, 則在編譯安裝 mysql 和 nginx時存在添加對應(yīng)的擴(kuò)展選項
- swap 策略: x<1024, y=1024; 1024<x<2048, y=2048; 2048<x<4096, y=4096; 4096<x<16384, y=8192; x>16384,y=8192
- swap 需要考慮剩余磁盤空間
- 安裝系統(tǒng)相關(guān)庫時, 需要動態(tài)鏈接
- 腳本運(yùn)行前執(zhí)行clear, 清空控制臺
軟件介紹
- FreeType庫是一個完全免費(fèi)(開源)的, 高質(zhì)量的且可移植的字體引擎, 它提供統(tǒng)一的接口來訪問多種字體格式文件
- PCRE(Perl Compatible Regular Expressions)是一個Perl庫, 包括 perl 兼容的正則表達(dá)式庫
- Boost庫是一個可移植、提供源代碼的C++庫
- cmake讀入所有源文件之后, 自動生成makefile, make依據(jù)makefile來批處理編譯
版本號
格式: major.minor.maintenance.build
- major: 是主版本號, 一般在軟件有重大升級時增長
- minor: 是次版本號, 一般在軟件有新功能時增長
- maintenance: 是維護(hù)版本, 一般在軟件有問題修復(fù)后增長
- build: 是構(gòu)建版本, 一般只要軟件被重新編譯過就會增長
.user.ini
配置參考地址: http://php.net/manual/zh/ini.list.php
- 只有 PHP_INI_USER 和 PHP_INI_ALL可以被 .user.ini 和 ini_set 還有 nginx 設(shè)置
- PHP_INI_PERDIR可在 php.ini, .htaccess 或 httpd.conf 中設(shè)定
- PHP_INI_SYSTEM 可在 php.ini 或 httpd.conf 中設(shè)定
- .user.ini 文件路徑 DOCUMENT_ROOT 下
nginx
- 通過增加配置PHP_ADMIN_VALUE設(shè)置 php.ini 的值, 優(yōu)先級高于 .user.ini
php.ini
- 默認(rèn)用戶配置文件為 .user.ini
文件描述符
- 系統(tǒng)級別: 使用cat /proc/sys/fs/file-max查看, 默認(rèn)值是根據(jù)內(nèi)存大小自動設(shè)置, 一般為內(nèi)存為 x KB, 則描述符數(shù)量為 x/10
- 用戶級別: 默認(rèn)為 1024
- 限制原因: 1. 內(nèi)存資源有限 2. 防止程序惡意創(chuàng)建, 影響系統(tǒng)穩(wěn)定性
- 用戶級別優(yōu)先級高于系統(tǒng)級別
系統(tǒng)級別
# 查看 cat /proc/sys/fs/file-max# 臨時設(shè)置 echo 1000000 > /proc/sys/fs/file-max# 永久設(shè)置 vi /etc/sysctl.conf fs.file-max = 1000000用戶級別
/etc/security/limits.conf
* soft nproc 65535 * hard nproc 65535 * soft nofile 65535 * hard nofile 65535- 第一列表示用戶和組(@開頭), * 表示所有用戶, 第二列表示軟限制還是硬限制, 第三列表示限制的資源類型, 第四列表示限制的最大值
- /etc/security/limits.d/ 里面配置會覆蓋 /etc/security/limits.conf 的配置
- core 是內(nèi)核文件, nofile 是文件描述符, noproc 是進(jìn)程
- hard和soft的區(qū)別: soft是一個警告值, 而hard則是一個真正意義的閥值, 超過就會報錯, 一般情況下都是設(shè)為同一個值
