1、依賴html
1. gcc 安裝
安裝 nginx 須要先將官網下載的源碼進行編譯,編譯依賴 gcc 環境,若是沒有 gcc 環境,則須要安裝:linux
yum install gcc-c++
2. PCRE pcre-devel 安裝
PCRE(Perl Compatible Regular Expressions) 是一個Perl庫,包括 perl 兼容的正則表達式庫。nginx 的 http 模塊使用 pcre 來解析正則表達式,因此須要在 linux 上安裝 pcre 庫,pcre-devel 是使用 pcre 開發的一個二次開發庫。nginx也須要此庫。命令:nginx
yum install -y pcre pcre-devel
3. zlib 安裝
zlib 庫提供了不少種壓縮和解壓縮的方式, nginx 使用 zlib 對 http 包的內容進行 gzip ,因此須要在 Centos 上安裝 zlib 庫。c++
yum install -y zlib zlib-devel
4. OpenSSL 安裝
OpenSSL 是一個強大的安全套接字層密碼庫,囊括主要的密碼算法、經常使用的密鑰和證書封裝管理功能及 SSL 協議,並提供豐富的應用程序供測試或其它目的使用。
nginx 不只支持 http 協議,還支持 https(即在ssl協議上傳輸http),因此須要在 Centos 安裝 OpenSSL 庫。git
yum install -y openssl openssl-devel
yum install -y gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel
2、安裝包下載github
直接下載.tar.gz
安裝包,地址:https://nginx.org/en/download.html正則表達式
wget -c https://nginx.org/download/nginx-1.14.0.tar.gz
3、解壓算法
tar zxvf nginx-1.14.0.tar.gz
4、配置安裝sql
cd nginx-1.14.0 ./configure --prefix=/usr/local/nginx --with-stream make && make install
mkdir -p /var/cache/nginx /etc/nginx/http.d /etc/nginx/stream.d
5、配置nginx轉發api
stream { upstream proxy_card { # simple round-robin 轉發IP和端口 server 192.168.1.12:12340; server 192.168.1.13:12340; #check interval=3000 rise=2 fall=5 timeout=1000; #check interval=3000 rise=2 fall=5timeout=1000 #check interval=3000 rise=2 fall=5timeout=1000 #check_http_send "GET /HTTP/1.0\r\n\r\n"; #check_http_expect_alive http_2xxhttp_3xx; } server { listen 12340; #監聽端口 proxy_pass proxy_card; #轉發請求 } }
6、工具
查找安裝路徑:
whereis nginx
啓動中止
cd /usr/local/nginx/sbin/ ./nginx ./nginx -s stop ./nginx -s quit ./nginx -s reload ./nginx -s quit:此方式中止步驟是待nginx進程處理任務完畢進行中止。 ./nginx -s stop:此方式至關於先查出nginx進程id再使用kill命令強制殺掉進程。
查詢nginx進程:
ps aux|grep nginx
重啓
1.先中止再啓動(推薦): 對 nginx 進行重啓至關於先中止再啓動,即先執行中止命令再執行啓動命令。以下: ./nginx -s quit ./nginx 2.從新加載配置文件: 當 ngin x的配置文件 nginx.conf 修改後,要想讓配置生效須要重啓 nginx,使用-s reload不用先中止 ngin x再啓動 nginx 便可將配置信息在 nginx 中生效,以下: ./nginx -s reload
自啓動:
即在rc.local增長啓動代碼就能夠了。 vi /etc/rc.local 增長一行 /usr/local/nginx/sbin/nginx 設置執行權限: chmod 755 rc.local
7、tcp轉發測試
編輯/etc/nginx/nginx.conf文件,追加
stream { log_format proxy '$remote_addr [$time_local] ' '$protocol $status $bytes_sent $bytes_received ' '$session_time "$upstream_addr" ' '"$upstream_bytes_sent" "$upstream_bytes_received" "$upstream_connect_time"'; access_log /var/log/nginx/stream.access.log proxy; upstream slb_test_apiserver_local { server 172.31.185.139:6443 weight=5 max_fails=3 fail_timeout=30s; server 172.31.185.138:6443 weight=5 max_fails=3 fail_timeout=30s; server 172.31.185.137:6443 weight=5 max_fails=3 fail_timeout=30s; } server { listen 6443; proxy_pass slb_test_apiserver_local; proxy_connect_timeout 1s; proxy_timeout 3s; access_log /var/log/nginx/slb_test_apiserver_local.log proxy; } }
重啓nginx,測試成功
8、快速編譯配置
快速編譯能夠應付大部分狀況
./configure --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib64/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --group=nginx --with-compat --with-file-aio --with-threads --with-http_addition_module --with-http_auth_request_module --with-http_dav_module --with-http_flv_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_mp4_module --with-http_random_index_module --with-http_realip_module --with-http_secure_link_module --with-http_slice_module --with-http_ssl_module --with-http_stub_status_module --with-http_sub_module --with-http_v2_module --with-mail --with-mail_ssl_module --with-stream --with-stream_realip_module --with-stream_ssl_module --with-stream_ssl_preread_module --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -fPIC' --with-ld-opt='-Wl,-z,relro -Wl,-z,now -pie' --add-module=/tmp/echo-nginx-module
其中,如不須要echo模塊,將最後一個選項去掉,如須要echo模塊,從github上面拉到指定位置
9、grpc協議轉發
upstream myservice { server 10.0.0.1:8888 weight=5 max_fails=3 fail_timeout=30s; server 10.0.0.2:8888 weight=5 max_fails=3 fail_timeout=30s; } server { listen 9999 http2 ; server_name www.myhost.com; if ( $host != "www.myhost.com"){ return 404; } location / { grpc_pass grpc://myservice; proxy_connect_timeout 1s; } access_log /var/log/nginx/myservice.log main; }
10、nginx.conf配置文件以下
user nobody; #Single core worker_processes 2; #Multicore #worker_processes 8; #worker_cpu_affinity 00000001 00000010 00000100 00001000 00010000 00100000 01000000 10000000; error_log /var/log/nginx/error.log warn; pid /var/run/nginx.pid; events { worker_connections 10240; } http { include /etc/nginx/mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for" "$http_host"' '$request_time $upstream_response_time $pipe - $upstream_addr'; log_format post_format $request_body; access_log /var/log/nginx/access.log main; sendfile on; #tcp_nopush on; keepalive_timeout 120; proxy_connect_timeout 600; proxy_send_timeout 600s; proxy_read_timeout 600s; #gzip on; include /etc/nginx/http.d/*.conf; } stream { log_format proxy '$remote_addr [$time_local] ' '$protocol $status $bytes_sent $bytes_received ' '$session_time "$upstream_addr" ' '"$upstream_bytes_sent" "$upstream_bytes_received" "$upstream_connect_time"'; access_log /var/log/nginx/stream.access.log proxy; include /etc/nginx/stream.d/*.conf; }
