LNMP和LAMP相識,只不過web服務由apache換成了nginx。javascript
而且php是做爲一個獨立服務存在的,這個服務叫作php-fpmphp
Nginx直接處理靜態請求,動態請求會轉發給php-fpmcss
在lamp中php做爲一個模塊,在lnmp中php是做爲一個服務。當用戶請求時nginx會把它交給php而後與mysql進行交互。靜態文件,如htmp或者圖片nginx會直接處理從而加快速度。html
因爲以前已安裝過mysql,這裏就略過。java
下載安裝包node
cd /usr/local/src/php-5.6.30
mysql
清理以前編譯的可執行文件及配置文件nginx
make clear
web
編譯安裝sql
執行如下語句:
./configure --prefix=/usr/local/php-fpm --with-config-file-path=/usr/local/php-fpm/etc --enable-fpm --with-fpm-user=php-fpm --with-fpm-group=php-fpm --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-pdo-mysql=/usr/local/mysql --with-mysql-sock=/tmp/mysql.sock --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-ftp --enable-mbstring --enable-exif --with-pear --with-curl --with-openssl
開始編譯:
make
make install
檢查是否報錯:
查看安裝路徑
ll /usr/local/php-fpm/
比以前安裝多了sbin和var兩個目錄:
sbin:啓動php-fpm服務目錄
var: 存放php日誌的目錄
配置php.ini
在解壓安裝包的目錄中複製php.ini-production文件到php-fpm/etc文件中,重命名爲php.ini
cp php.ini-production /usr/local/php-fpm/etc/php.ini
配置php-fpm.conf
vi /usr/local/php-fpm/etc/php-fpm.conf
寫入如下內容:
[global] pid = /usr/local/php-fpm/var/run/php-fpm.pid error_log = /usr/local/php-fpm/var/log/php-fpm.log [www] listen = /tmp/php-fcgi.sock listen.mode = 666 user = php-fpm group = php-fpm pm = dynamic pm.max_children = 50 pm.start_servers = 20 pm.min_spare_servers = 5 pm.max_spare_servers = 35 pm.max_requests = 500 rlimit_files = 1024
設置啓動腳本
把安裝解壓包中的init.d.php-fpm文件複製到/etc/init.d/並更名爲php-fpm
cp /usr/local/src/php-5.6.30/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
賦予775權限
chmod 755 /etc/init.d/php-fpm
啓動php
service php-fpm start
查看php進程
ps -ef|grep php-fpm
Nginx簡介
Nginx官網:nginx.org
Nginx應用場景:web服務、反向代理、負載均衡
Nginx分支:淘寶基於nginx開發的Tengine,使用與nginx一致。區別在於Tengine增長了一些定製化模塊,在安全限速方面表現突出,另外它支持對接js/css合併。Nginx+lua相關組件和模塊組成支持lua的高性能openresty,參考: http://jinnianshilongnian.iteye.com/blog/2280928
Nginx特色
體積小
處理能力強
併發高
可擴展性高
下載nginx安裝包
cd /usr/local/src
wget http://nginx.org/download/nginx-1.17.0.tar.gz
編譯安裝
cd /usr/local/src/nginx-1.17.0
./configure --prefix=/usr/local/nginx
make && make install
查看nginx安裝目錄
conf:nginx配置文件
html:主頁樣例文件
logs:日誌
sbin:核心進程文件
Nginx啓動配置文件
vim /etc/init.d/nginx
寫入如下內容:
#!/bin/bash # chkconfig: - 30 21 # description: http service. # Source Function Library . /etc/init.d/functions # Nginx Settings NGINX_SBIN="/usr/local/nginx/sbin/nginx" NGINX_CONF="/usr/local/nginx/conf/nginx.conf" NGINX_PID="/usr/local/nginx/logs/nginx.pid" RETVAL=0 prog="Nginx" start() { echo -n $"Starting $prog: " mkdir -p /dev/shm/nginx_temp daemon $NGINX_SBIN -c $NGINX_CONF RETVAL=$? echo return $RETVAL } stop() { echo -n $"Stopping $prog: " killproc -p $NGINX_PID $NGINX_SBIN -TERM rm -rf /dev/shm/nginx_temp RETVAL=$? echo return $RETVAL } reload() { echo -n $"Reloading $prog: " killproc -p $NGINX_PID $NGINX_SBIN -HUP RETVAL=$? echo return $RETVAL } restart() { stop start } configtest() { $NGINX_SBIN -c $NGINX_CONF -t return 0 } case "$1" in start) start ;; stop) stop ;; reload) reload ;; restart) restart ;; configtest) configtest ;; *) echo $"Usage: $0 {start|stop|reload|restart|configtest}" RETVAL=1 esac exit $RETVAL
啓動nginx
修改權限爲755
chmod 755 /etc/init.d/nginx
設置開機啓動
chkconfig --add nginx
chkconfig nginx on
啓動/關閉/檢查
啓動:
/usr/local/nginx/sbin/nginx
service nginx start
關閉:
pkill nginx
//殺死nginx進程,中止nginx服務
檢查:
/usr/local/nginx/sbin/nginx -t
//檢測配置文件語法錯誤
啓動並查看進程
service nginx start
修改nginx配置文件
nginx配置文件:
vim /usr/local/nginx/conf/nginx.conf
添加如下內容:
user nobody nobody; worker_processes 2; error_log /usr/local/nginx/logs/nginx_error.log crit; pid /usr/local/nginx/logs/nginx.pid; worker_rlimit_nofile 51200; events { use epoll; worker_connections 6000; } http { include mime.types; default_type application/octet-stream; server_names_hash_bucket_size 3526; server_names_hash_max_size 4096; log_format combined_realip '$remote_addr $http_x_forwarded_for [$time_local]' ' $host "$request_uri" $status' ' "$http_referer" "$http_user_agent"'; sendfile on; tcp_nopush on; keepalive_timeout 30; client_header_timeout 3m; client_body_timeout 3m; send_timeout 3m; connection_pool_size 256; client_header_buffer_size 1k; large_client_header_buffers 8 4k; request_pool_size 4k; output_buffers 4 32k; postpone_output 1460; client_max_body_size 10m; client_body_buffer_size 256k; client_body_temp_path /usr/local/nginx/client_body_temp; proxy_temp_path /usr/local/nginx/proxy_temp; fastcgi_temp_path /usr/local/nginx/fastcgi_temp; fastcgi_intercept_errors on; tcp_nodelay on; gzip on; gzip_min_length 1k; gzip_buffers 4 8k; gzip_comp_level 5; gzip_http_version 1.1; gzip_types text/plain application/x-javascript text/css text/htm application/xml; server { listen 80; server_name localhost; index index.html index.htm index.php; root /usr/local/nginx/html; location ~ \.php$ { include fastcgi_params; fastcgi_pass unix:/tmp/php-fcgi.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name; } } }

vim /usr/local/nginx/html/1.php
添加如下內容:
<?phpecho "hello";
測試:
curl localhost/1.php
