`
+
++ 更新系统：`sudo apt update && sudo apt upgrade -y`
+
+## 从源代码构建NGINX
+
++ NGINX是用C编写的程序，所以我们需要安装C编译器（GCC）。
+
+ ```bash
+ sudo apt install build-essential -y
+ ```
+
++ 下载最新版本的NGINX源代码并解压缩：
+
+ ```bash
+ wget https://nginx.org/download/nginx-1.13.1.tar.gz && tar zxvf nginx-1.13.1.tar.gz
+ ```
++ 下载NGINX依赖项的源代码并解压缩
+
+ > NGINX依赖于3个库：PCRE，zlib和OpenSSL：
+
+ ```bash
+ # PCRE version 4.4 - 8.40
+ wget https://ftp.pcre.org/pub/pcre/pcre-8.40.tar.gz && tar xzvf pcre-8.40.tar.gz
+
+ # zlib version 1.1.3 - 1.2.11
+ wget http://www.zlib.net/zlib-1.2.11.tar.gz && tar xzvf zlib-1.2.11.tar.gz
+
+ # OpenSSL version 1.0.2 - 1.1.0
+ wget https://www.openssl.org/source/openssl-1.1.0f.tar.gz && tar xzvf openssl-1.1.0f.tar.gz
+ ```
+
++ 删除所有.tar.gz文件。我们不再需要了
+
+ ```bash
+ wget https://nginx.org/download/nginx-1.13.1.tar.gz && tar zxvf nginx-1.13.1.tar.gz
+ ```
+
++ 转到NGINX源目录：``
+
+ cd ~/nginx-1.13.1
+
++ 有关帮助，您可以通过运行以下列出可用的配置开关
+
+ ./configure --help
+
++ 配置，编译和安装NGINX：
+

+ rm -r nginx-1.13.1/ openssl-1.1.0f/ pcre-8.40/ zlib-1.2.11/
+
++ 检查NGINX版本和编译时间选项：
+
+ sudo nginx -v && sudo nginx -V
+
+ # nginx version: nginx/1.13.0 (Ubuntu)
+ # built by gcc 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.4)

+ # TLS SNI support enabled
+ # configure arguments: --prefix=/etc/nginx . . .
+ # . . .
+ # . . .
+
++ 检查语法和潜在错误：
+
+ sudo nginx -t
+ # Will throw this error nginx: [emerg] mkdir() "/var/lib/nginx/body" failed (2: No such file or directory)
+ # Just create directory
+ mkdir -p /var/lib/nginx && sudo nginx -t
+
++ 为NGINX创建systemd单元文件：
+
+ sudo vim /etc/systemd/system/nginx.service
+
++ 复制/粘贴以下内容：
+ > 注意：根据NGINX的编译方式，PID文件和NGINX二进制文件的位置可能不同。
+

+ KillMode=mixed
+
+ [Install]
+ WantedBy=multi-user.target
+
++ 启动并启用NGINX服务：
+
+ sudo systemctl start nginx.service && sudo systemctl enable nginx.service
+
++ 检查NGINX是否在重启后启动：
+
+ sudo systemctl is-enabled nginx.service
+ # enabled
+
++ 检查NGINX是否正在运行：
+
+ sudo systemctl status nginx.service
+ ps aux | grep nginx
+ curl -I 127.0.0.1
+
++ 重新启动Ubuntu VPS以验证NGINX是否自动启动：
+
+ sudo shutdown -r now
+
++ 创建UFW NGINX应用程序配置文件：
+
+ sudo vim /etc/ufw/applications.d/nginx
+
++ 复制/粘贴以下内容：
+
+ [Nginx HTTP]

+ 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
+ opcache.huge_code_pages=1
+ opcache.file_cache=/tmp
+ ```
++ 缓存文件记录
+
+ ```bash
+ www@TinywanAliYun:/tmp$ tree -L 6
+ .
+ ├── 8fc9c56d14b6542c6ff7147207730f6b
+ │ └── home

+ │ └── web
+ │ └── go-study-line
+ │ ├── application
+ │ ├── config
+ │ ├── public
+ │ ├── runtime
+ │ ├── thinkphp
+ │ └── vendor
+ ```
++ 使用新的编译器,使用新一点的编译器, 推荐GCC 4.8以上, 因为只有GCC 4.8以上PHP才会开启Global Register for opline and execute_data支持, 这个会带来5%左右的性能提升
+
++ 开启HugePages,然后开启Opcache的huge_code_pages
+
+ + 系统中开启HugePages
+
+ ```bash
+ sudo sysctl vm.nr_hugepages=512
+ ```
+ + 分配512个预留的大页内存
+
+ ```bash
+ $ cat /proc/meminfo | grep Huge
+ AnonHugePages: 106496 kB
+ HugePages_Total: 512
+ HugePages_Free: 504
+ HugePages_Rsvd: 27
+ HugePages_Surp: 0
+ Hugepagesize: 2048 kB
+ ```
+ + 然后在php.ini中加入，`opcache.huge_code_pages=1`
+
+ + 开启Opcache File Cache,`opcache.file_cache=/tmp`
+
+ + 启用Zend Opcache
+ +
+## PHP-FPM优化
+
++ 结构
+
+ ```bash
+ +---> php.ini PHP配置文件
+ |
+ PHP-->|---> php-fpm 服务控制脚本
+ +---> php-fpm.conf 进程服务主配置文件
+ |
+ +---> www.conf 进程服务扩展配置文件
+ ```
++ `php.ini`
+
+ ```php
+ # 设置错误日志的路径
+ error_log = /var/log/php-fpm/error.log
+
+ # 引入www.conf文件中的配置
+ include=/usr/local/php7/etc/php-fpm.d/*.conf
+
+ # 设置主进程打开的最大文件数
+ rlimit_files = 102400
+ ```
+
++ `php-fpm.conf` 进程服务主配置文件
+
+ ```php

+ # 设置错误日志的路径
+ error_log = /var/log/php-fpm/error.log
+
+ # 引入www.conf文件中的配置
+ include=/usr/local/php7/etc/php-fpm.d/*.conf
+
+ # 设置主进程打开的最大文件数
+ rlimit_files = 65535
+ ```
+
++ `www.conf` 进程服务扩展配置文件
+
+ ```php
+ # 设置启动进程的帐户和组
+ user = www
+ group = www
+
+ # 设置php监听方式,注意这里要设置PHP套接字文件的权限，默认是root，Nginx无法访问
+ # listen = 127.0.0.1:9000
+ listen = /var/run/php-fpm/php-fpm.sock
+
+ #backlog数，-1表示无限制，由操作系统决定，此行注释掉就行。backlog含义参考：http://www.3gyou.cc/?p=41
+
+ listen.allowed_clients = 127.0.0.1
+ # 允许访问FastCGI进程的IP，设置any为不限制IP，如果要设置其他主机的nginx也能访问这台FPM进程，
+ # listen处要设置成本地可被访问的IP。默认值是any。每个地址是用逗号分隔.
+ # 如果没有设置或者为空，则允许任何服务器请求连接
+
+ #backlog数，-1表示无限制，由操作系统决定，此行注释掉就行。backlog含义参考：http://www.3gyou.cc/?p=41

+ request_slowlog_timeout = 10s
+ request_terminate_timeout = 30
+
+ #对于专用服务器，pm可以设置为static。
+ pm = dynamic
+
+ # 设置工作进程数(根据实际情况设置)
+ pm.max_children = 50
+
+ # pm.start_servers不能小于pm.min_spare_servers,推荐为最大的pm.max_children的%10
+ pm.start_servers = 8
+ pm.min_spare_servers = 5
+ pm.max_spare_servers = 10
+ pm.max_requests = 10240
+
+ # cat /usr/local/php-5.5.10/etc/php-fpm.conf | grep status_path
+ pm.status_path = /status
+
+ # 设置扩展配置主进程打开的最大文件数
+ rlimit_files = 65535
+
+ # 设置php的session目录（所属用户和用户组都是www）
+ php_value[session.save_handler] = files
+ php_value[session.save_path] = /var/tmp/php/session
+ ```
+
++ 调整PHP-FPM（Nginx）的子进程
+ + 日志中出现以下警告消息,这意味着没有足够的PHP-FPM进程
+
+ ```php
+ [19-Aug-2017 01:02:20] WARNING: [pool www] seems busy (you may need to increase pm.start_servers, or pm.min/max_spare_servers)
+ [19-Aug-2017 01:02:21] WARNING: [pool www] server reached pm.max_children setting (256), consider raising it
+ ```
+
+ + 根据系统内存量来计算和更改这些值，` /etc/php-fpm.d/www.conf`
+
+ ```php
+ pm.max_children = 50
+ pm.start_servers = 5
+ pm.min_spare_servers = 5
+ pm.max_spare_servers = 35
+ ```
+
+ + 以下命令将帮助我们确定每个（PHP-FPM）子进程使用的内存：
+
+ > RSS列显示PHP-FPM进程的未交换的物理内存使用量，单位为千字节
+ > 平均每个PHP-FPM进程在我的机器上占用大约75MB的RAM
+
+ ```php
+ ps -ylC php-fpm --sort:rss
+ ```
+
+ + pm.max_children的适当值可以计算为:
+
+ ```php
+ pm.max_children = Total RAM dedicated to the web server / Max child process size
+ ```
+
+ + 在我的情况下是56MB,服务器有16GB的RAM，所以：
+
+ >我留下了一些记忆，让系统呼吸。在计算内存使用情况时，您需要考虑计算机上运行的任何其他服务。
+
+ ```php
+ pm.max_children = 15806MB / 56MB = 282
+ # Tinywan 计算方式(实战)
+ # pm.max_children = (15806MB - 1024MB) / 57MB = 259
+ ```
+
+ + 已经改变了如下设置
+ >请注意，非常高的价值并不意味着任何好处
+
+ ```php
+ pm.max_children = 256
+ pm.start_servers = 32
+ pm.min_spare_servers = 32
+ pm.max_spare_servers = 128
+ pm.max_requests = 65535
+ ```
+
+ + 您可以使用此方便的命令检查单个PHP-FPM进程的平均内存使用情况
+
+ ```php
+ ps --no-headers -o "rss,cmd" -C php-fpm | awk '{ sum+=$1 } END { printf ("%d%s\n", sum/NR/1024,"M") }'
+ ```

++ 各个phase说明
+ + (1) post read phase
+ > `post-read ` 属于 `rewrite`阶段
+
+ > `post-read` 支持Nginx模块的钩子
+
+ > 内置模块 `ngx_realip` 把它的处理程序`post-read`分阶段挂起，强制重写请求的原始地址作为特定请求头的值
+
+ ```
+ server {
+ listen 8080;
+
+ set_real_ip_from 127.0.0.1;
+ real_ip_header X-My-IP;
+
+ location /test {
+ set $addr $remote_addr;
+ echo "from: $addr";
+ }
+ }
+ ```
+
+ > 该配置告诉Nginx强制将每个请求的原始地址重写127.0.0.1为请求头的值X-My-IP。同时它使用内置变量 `$remote_addr`来输出请求的原始地址
+
+ ```
+ $ curl -H 'X-My-IP: 1.2.3.4' localhost:8080/test
+ from: 1.2.3.4
+ ```
+ > curl 参数 -H ：自定义头信息传递给服务器
+
+ > 该选项X-My-IP: 1.2.3.4在请求中包含一个额外的HTTP头
+
+ > 测试结果
+ ```
+ $ curl localhost:8080/test
+ from: 127.0.0.1
+
+ $ curl -H 'X-My-IP: abc' localhost:8080/test
+ from: 127.0.0.1
+ ``
+
+ + server_rewrite phase
+
+ > 这个阶段主要进行初始化全局变量，或者server级别的重写。如果把重写指令放到 server 中，那么就进入了server rewrite 阶段。（重写指令见rewrite phase）
+
+ > ( 1 ) `server-rewrite ` 阶段运行时间早于 `rewrite` 阶段
+
+ ```
+ location /tinywan {
+ set $bbb "$aaa, world";
+ echo $bbb;
+ }
+ set $aaa "HELLO";
+ ```
+
+ > `set $a hello` 声明被放在`server`指令中，所以它运行在`server-rewrite`阶段
+
+ > 因此 `set $b "$a, world'" `，在location指令中执行 `set ` 指令后，它将获得正确的`$a`值
+
+ > 执行结果
+
+ ```
+ # curl http://127.0.0.2:8008/tinywan
+ HELLO, world
+ ```
+ > ( 2 ) `post-read` 阶段阶段运行时间早于 `server-rewrite` 阶段执行
+
+ ```
+ server {
+ listen 8080;
+
+ set $addr $remote_addr;
+
+ set_real_ip_from 127.0.0.1;
+ real_ip_header X-Real-IP;
+
+ location /test {
+ echo "from: $addr";
+ }
+ }
+ ```
+
+ > ( 3 ) `ngx_realip` 阶段阶段运行时间早于 `server 的 set 指令` 阶段执行
+
+ ```
+ $ curl -H 'X-Real-IP: 1.2.3.4' localhost:8080/test
+ from: 1.2.3.4
+ ```
+
+ > 服务器指令中的命令集始终比模块ngx_realip晚，
+
+ > ( 4 ) `server-rewrite` 阶段阶段运行时间早于 `find-config` 阶段执行
+
+ + find config phase
+ > ( 5 ) `find-config` 阶段阶段运行时间早于 `rewrite` 阶段执行
+
+ > 这个阶段使用重写之后的uri来查找对应的location，值得注意的是该阶段可能会被执行多次，因为也可能有location级别的重写指令。这个阶段并不支持 Nginx 模块注册处理程序，而是由 Nginx 核心来完成当前请求与 location 配置块之间的配对工作
+
+ + rewrite phase：
+ > 如果把重写指令放到 location中，那么就进入了rewrite phase，这个阶段是location级别的uri重写阶段，重写指令也可能会被执行多次
+
+ > 有`HttpRewriteModule` 的set指令、rewrite指令
+
+ > HttpLuaModule的 set_by_lua指令,
+
+ > ngx_set_misc模块的set_unescape_uri指令
+
+ > 另外HttpRewriteModule的几乎所有指令都属于rewrite阶段。
++ 结论：作用域为同一个phase的不同modules的指令，如果modules之间做了特殊的兼容，则它们按照指令在配置文件中出现的顺序依次执行下来
++ HttpLuaModule 模块指令
+ + init_by_lua
+ > 在nginx重新加载配置文件时，运行里面lua脚本，常用于全局变量的申请。例如lua_shared_dict共享内存的申请，只有当nginx重起后，共享内存数据才清空，这常用于统计。
+
+ + set_by_lua
+ > 设置一个变量，常用与计算一个逻辑，然后返回结果,该阶段不能运行Output API、Control API、Subrequest API、Cosocket API
+
+ + rewrite_by_lua
+ > 在access阶段前运行，主要用于rewrite
+
+ + access_by_lua
+ > 主要用于访问控制，能收集到大部分变量，类似status需要在log阶段才有。这条指令运行于nginx access阶段的末尾，因此总是在 allow 和 deny 这样的指令之后运行，虽然它们同属 access 阶段。
+
+ + content_by_lua
+ > 阶段是所有请求处理阶段中最为重要的一个，运行在这个阶段的配置指令一般都肩负着生成内容（content）并输出HTTP响应。
+
+ + header_filter_by_lua
+ > 一般只用于设置Cookie和Headers等,该阶段不能运行Output API、Control API、Subrequest API、Cosocket API
+
+ + body_filter_by_lua
+ > 一般会在一次请求中被调用多次, 因为这是实现基于 HTTP 1.1 chunked 编码的所谓“流式输出”的,该阶段不能运行Output API、Control API、Subrequest API、Cosocket API
+
+ + log_by_lua
+ > 该阶段总是运行在请求结束的时候，用于请求的后续操作，如在共享内存中进行统计数据,如果要高精确的数据统计，应该使用body_filter_by_lua
+
++ --with-http_realip_module 模块
+ + set_real_ip_from 192.168.1.0/24; 指定接收来自哪个前端发送的 IP head 可以是单个IP或者IP段
+ + set_real_ip_from 192.168.2.1;
+ + real_ip_header X-Real-IP; IP head 的对应参数，默认即可。

+### PHP-FPM 服务
++ 下载文件[php-fpm.sh](https://github.com/Tinywan/Lua-Nginx-Redis/blob/master/PHP/PHP-FPM/php-fpm.sh)
++ 注意配置文件：`sudo vim /usr/local/php-7.2/etc/php-fpm.conf`
+ > 务必开启配置文件的pid路径：`pid = run/php-fpm.pid`
+ 否则会报错：`no pid file found - php-fpm is not running ?`
++ CP到默认开启的服务脚本：
+
+ ```
+ sudo cp php-fpm.sh /etc/init.d/php-fpm
+ ```
++ 给予权限：
+
+ ```
+ sudo chmod +x /etc/init.d/php-fpm

+### Nginx 服务
+
++ 第一种安装方式
+ + 查看当前nginx是否已经在开机启动项里面:
+
+ ```bash
+ ls /etc/rc*
+ ```
+ + 如何安装
+
+ ```bash
+ #使用wget -O 下载并以不同的文件名保存
+ sudo wget https://raw.github.com/JasonGiedymin/nginx-init-ubuntu/master/nginx -O /etc/init.d/nginx
+ # 给与权限
+ sudo chmod +x /etc/init.d/nginx
+ # 设置为启动项
+ sudo update-rc.d nginx defaults
+ ```
+ + 需要修改的地方：
+ + 1、`NGINXPATH=${NGINXPATH:-/opt/openresty/nginx}` 修改为自己的路径
+ + 2、`PIDSPATH=${PIDSPATH:-$NGINXPATH/logs}` pid文件路径
+ > 如果在配置文件修改为：`pid /run/nginx.pid;`
+ PIDSPATH=${PIDSPATH:-$NGINXPATH/logs}修改为：PIDSPATH="/run"
++ 第二种安装方式
+ + 和PHP-FPM一样，`nginx.sh`代码
