安裝Nginx
首先拉下centos鏡像docker pull centos
我們安裝最新的nginx1.19版本:下載地址
將centos鏡像運(yùn)行起來(lái)并進(jìn)入:
docker run --name ver -d -p 8051:80 -it nginx_start
將nginx-1.19.0.tar.gz這個(gè)包放入容器里面:
docker cp nginx-1.19.0.tar.gz 10e87af84c05:/root
(10e87af84c05為centos容器id)
安裝nginx前先裝一些依賴:
yum -y install gcc gcc-c++ autoconf automake make
yum -y install zlib zlib-devel openssl openssl-devel pcre pcre-devel
解壓:
tar -zxvf nginx-1.19.0.tar.gz
#進(jìn)入到nginx-1.10.1 ,并配置nginx
cd nginx-1.19.0
#配置nginx
#--prefix 指定安裝的目錄
#/usr/local/nginx 是安裝目錄,不能和自己下載的文件目錄重了
#./configure --prefix=/usr/local/nginx
#帶ssl stub_status模塊 添加strem模塊 –with-stream,這樣就能傳輸tcp協(xié)議了
#http_stub_status_module 狀態(tài)監(jiān)控
#http_ssl_module 配置https
#stream 配置tcp得轉(zhuǎn)發(fā)
#http_gzip_static_module 壓縮
#http_sub_module 替換請(qǐng)求
./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-stream
注:
在這里我出現(xiàn)了pcre和zlib缺失的錯(cuò),可以使用yum -y install zlib zlib-devel openssl openssl--devel pcre pcre-devel
命令,安裝所有依賴。
再 make & make install
進(jìn)行編譯安裝
安裝成功后,在./configure --prefix=/usr/local/nginx
指定目錄會(huì)生成四個(gè)文件,我們也只需要輸入/usr/local/nginx/sbin/nginx
來(lái)啟動(dòng)nginx服務(wù)即可。
要驗(yàn)證是否成功,可以輸入curl localhost
來(lái)查看是否啟動(dòng)成功。
生成鏡像
10. 將裝有nginx的centos容器打包為鏡像docker commit ba5ba0d81912 nginx_centos
(ba5ba0d81912 為容器ID,重命名為nginx_centos)
11. 重新運(yùn)行新的鏡像:docker run --name ver -d -p 8051:80 -it nginx_centos
12. 而此時(shí)的鏡像,則是有我們安裝好的nginx,我們就可以拿他開(kāi)始為所欲為,做一些其他的騷操作了。
安裝python2.7環(huán)境
yum install gcc openssl-devel bzip2-devel
用 wget 下載 python 2.7 并解壓
進(jìn)入目錄 /usr/src 再用 wget 下載 python 2.7
cd /usr/src
wget https://www.python.org/ftp/python/2.7.15/Python-2.7.15.tgz
再解壓 python2.7
tar -zxvf Python-2.7.15.tgz
安裝 python 2.7
進(jìn)入上面解壓的 Python-2.7.15 解壓文件中使用下面命令行安裝
cd Python-2.7.15
./configure --enable-optimizations
make altinstall
安裝 PIP
curl "https://bootstrap.pypa.io/get-pip.py" -o "get-pip.py"
python2.7 get-pip.py
因?yàn)榘姹緸?.7,且requirements.txt里面有一個(gè) MYSQL-python
的庫(kù),會(huì)報(bào)一個(gè)找不到libmysqlclient-dev
的錯(cuò),執(zhí)行yum install mysql-devel
即可解決。
安裝UWSGI
pip install uwsgi
的時(shí)候會(huì)報(bào)一個(gè)錯(cuò):
plugins/python/uwsgi_python.h:2:20: fatal error: Python.h: No such file or directory
#include <Python.h>
運(yùn)行yum install python-devel.x86_64
即可解決,并重新pip install即可下載。
配置uWSGI服務(wù)器
相關(guān)uwsgi.ini
文件內(nèi)容如下:
[uwsgi]
socket = /tmp/uwsgi.sock
chown-socket = nginx:nginx
chmod-socket = 664
# Graceful shutdown on SIGTERM, see https://github.com/unbit/uwsgi/issues/849#issuecomment-118869386
hook-master-start = unix_signal:15 gracefully_kill_them_all
在項(xiàng)目目錄下/app/創(chuàng)建uwsgi.ini
文件:
[uwsgi]
uwsgi-socket = /tmp/uwsgi.sock
chmod-socket = 777
callable = app
wsgi-file = main.py
buffer-size = 65535
processes = %(%k * 2)
threads = %(%k * 20
其中每個(gè)參數(shù)的意思:
uwsgi-socket:將uwsgi-socket這個(gè)配置項(xiàng)指定了一個(gè)文件,這個(gè)文件是Unix套接字,即通過(guò)文件系統(tǒng)
(而非網(wǎng)絡(luò)地址)進(jìn)行尋址和訪問(wèn)的套接字。配置uwsgi-socket之后,還需要配置chmod-socket,
Unix socket是個(gè)文件,所以會(huì)受到Unix系統(tǒng)的權(quán)限限制,可以配置成660或者777,
使得uwsgi客戶端能夠訪問(wèn)這個(gè)Unix socket文件,這里配置為777。
callable:設(shè)置在收到請(qǐng)求時(shí),uwsgi加載的模塊中哪個(gè)變量將被調(diào)用,默認(rèn)是名字為“application”的變量。
wsgi-file:加載指定的wsgi文件。
buffer-size:設(shè)置用于uwsgi包解析的內(nèi)部緩存區(qū)大小。默認(rèn)是4k。
processes和threads,分別是開(kāi)啟的進(jìn)程數(shù)和線程數(shù),而%k是魔數(shù)變量,代表CPU核數(shù),如果我們是雙核CPU,
那這里的processes和threads分別為4和40,即有4個(gè)進(jìn)程,每個(gè)進(jìn)程有40個(gè)線程。
安裝Supervisor(可選)
直接yum安裝會(huì)報(bào)一個(gè)No package supervisor available.
的錯(cuò)誤,那是因?yàn)镃entOS是RedHat企業(yè)版編譯過(guò)來(lái)的,去掉了所有關(guān)于版權(quán)問(wèn)題的東西。只需要執(zhí)行yum install epel-release
即可解決。安裝好后會(huì)生成如下目錄:
現(xiàn)在我們將配置supervisor,使得supervisor監(jiān)聽(tīng)nginx和uwsgi服務(wù)。
首先在/etc
目錄下創(chuàng)建supervisor
文件,然后創(chuàng)建supervisord.conf
文件和conf.d目錄:
supervisord.conf目錄配置如下:
; supervisor config file
[unix_http_server]
file=/var/run/supervisor/supervisor.sock ; (the path to the socket file)
chmod=0700 ; sockef file mode (default 0700)
[supervisord]
logfile=/var/log/supervisor/supervisord.log ; (main log file;default $CWD/supervisord.log)
pidfile=/var/run/supervisord.pid ; (supervisord pidfile;default supervisord.pid)
childlogdir=/var/log/supervisor ; ('AUTO' child log dir, default $TEMP)
; the below section must remain in the config file for RPC
; (supervisorctl/web interface) to work, additional interfaces may be
; added by defining them in separate rpcinterface: sections
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface
[supervisorctl]
serverurl=unix:///var/run/supervisor.sock ; use a unix:// URL for a unix socket
; The [include] section can just contain the "files" setting. This
; setting can list multiple files (separated by whitespace or
; newlines). It can also contain wildcards. The filenames are
; interpreted as relative to this file. Included files *cannot*
; include files themselves.
[include]
files = /etc/supervisor/conf.d/*.conf
再在conf.d目錄下創(chuàng)建supervisord.conf
文件并編輯:
[supervisord]
nodaemon=true
[program:uwsgi]
command=/usr/bin/uwsgi --ini /etc/uwsgi/uwsgi.ini --die-on-term --need-app
stdout_logfile=/dev/stdout
stdout_logfile_maxbytes=0
stderr_logfile=/dev/stderr
stderr_logfile_maxbytes=0
[program:nginx]
command=/usr/local/nginx/sbin/nginx
stdout_logfile=/dev/stdout
stdout_logfile_maxbytes=0
stderr_logfile=/dev/stderr
stderr_logfile_maxbytes=0
# Graceful stop, see http://nginx.org/en/docs/control.html
stopsignal=QUIT
以上路徑均為實(shí)際目錄配置,如果有不一樣則需要更改。
然后將supervisor啟動(dòng):
以上配置弄好后,我們將容器重新打包生成一個(gè)新的鏡像,記為base_v3
,我們寫一個(gè)打包docker應(yīng)用的Dockerfile:
FROM base_v3
# 創(chuàng)建工作路徑
RUN mkdir /app
# 指定容器啟動(dòng)時(shí)執(zhí)行的命令都在app目錄下執(zhí)行
WORKDIR /app
# 替換nginx的配置
COPY nginx.conf /etc/nginx/nginx.conf
# 將本地app目錄下的內(nèi)容拷貝到容器的app目錄下
COPY ./app/ /app/
這里,在Dockerfile和app同級(jí)目錄下,再建立一個(gè)nginx.conf文件,并將nginx.conf內(nèi)容修改如下:
user nginx;
worker_processes 1;
error_log /usr/local/nginx/logs/error.log warn;
pid /usr/local/nginx/logs/nginx.pid;
worker_rlimit_nofile 20480;
events {
use epoll;
worker_connections 20480;
multi_accept on;
}
http {
include /usr/local/nginx/conf/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
#請(qǐng)求量級(jí)大建議關(guān)閉acccess_log
#access_log /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;
keepalive_timeout 300s;
client_header_timeout 300s;
client_body_timeout 300s;
gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_types text/html application/javascript application/json;
include /usr/local/nginx/conf.d/*.conf;
server {
listen 6666;
charset utf-8;
client_max_body_size 75M;
location / {
include uwsgi_params;
uwsgi_pass unix:///tmp/uwsgi.sock;
uwsgi_send_timeout 300;
uwsgi_connect_timeout 300;
uwsgi_read_timeout 300;
}
}
}
接下來(lái)只需要docker build -t new_project .
并docker run --name test -d -p 8055:6666 -v /root/web/mim_backend/data:/app/static -v /root/logs/mim_backend:/app/log -it new_project
即可。
當(dāng)然,這個(gè)時(shí)候進(jìn)去nginx和uwsgi沒(méi)有自動(dòng)啟動(dòng),需要手動(dòng)拉起來(lái),如想自動(dòng)拉起服務(wù),可選用supervisor或者在dockerfile里面加一個(gè)ENTRYPOINT nginx -g "daemon on;" && uwsgi --ini /app/uwsgi.ini
然后隨便跑一個(gè)接口測(cè)試:
