一、項(xiàng)目背景和要求
公司在實(shí)際的生產(chǎn)環(huán)境中，需要使用Docker 技術(shù)在一臺主機(jī)上創(chuàng)建LNMP服務(wù)并運(yùn)行Wordpress網(wǎng)站平臺。
然后對此服務(wù)進(jìn)行相關(guān)的性能調(diào)優(yōu)和管理工作
二、項(xiàng)目環(huán)境
| 主機(jī) | 操作系統(tǒng) | IP地址 | 主要軟件 |
|---|---|---|---|
| 宿主機(jī) | CentOS 7.3 x86_64 | 192.168.2.106 | Docker 19.03 |
| Nginx容器 | 172.18.0.10 | ||
| Mysql容器 | 172.18.0.20 | ||
| PHP容器 | 172.18.0.30 |
三、部署過程
1）創(chuàng)建自定義網(wǎng)絡(luò)
#關(guān)閉防火墻和selinux
systemctl stop firewalld
systemctl disable firewalld
setenforce 0
#創(chuàng)建自定義網(wǎng)絡(luò)
docker network create --subnet=172.18.0.0/16 --opt "com.docker.network.bridge.name"="docker1" mynetwork
2）部署Nginx
容器IP：172.18.0.10
Step1 創(chuàng)建工作目錄并上傳相關(guān)軟件包
mkdir /opt/nginx
cd /opt/nginx
mkdir /opt/nginx/html
tar zxvf wordpress-4.9.4-zh_CN.tar.gz -C /opt/nginx/html
Step2 編寫Dockerfile文件
vim Dockerfile
FROM centos:7
MAINTAINER this is nginx image <wl>
RUN yum -y install pcre-devel zlib-devel gcc gcc-c++ make
RUN useradd -M -s /sbin/nologin nginx
ADD nginx-1.24.0.tar.gz /usr/local/src/
WORKDIR /usr/local/src/nginx-1.24.0
RUN ./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module && make && make install
ENV PATH /usr/local/nginx/sbin:$PATH
ADD nginx.conf /usr/local/nginx/conf/
#ADD wordpress-4.9.4-zh_CN.tar.gz /usr/local/nginx/html/
RUN chmod 777 -R /usr/local/nginx/html/
EXPOSE 80
EXPOSE 443
ENTRYPOINT [ "/usr/local/nginx/sbin/nginx", "-g", "daemon off;" ]
Step3 編寫配置文件nginx.conf
vim nginx.conf
#user nobody;
worker_processes 2;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;

use epoll
worker_connections 1024;
}
http {
include 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"';
#access_log logs/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;
server {
listen 80;
server_name www.byyb.com;
charset utf-8;
#access_log logs/host.access.log main;
location / {
root html;
index index.php index.html;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
root html;
fastcgi_pass 172.18.0.30:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;
include fastcgi_params;
}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
# listen 8000;
# listen somename:8080;
# server_name somename alias another.alias;
# location / {
# root html;
# index index.html index.htm;
# }
#}
# HTTPS server
#
#server {
# listen 443 ssl;
# server_name localhost;
# ssl_certificate cert.pem;
# ssl_certificate_key cert.key;
# ssl_session_cache shared:SSL:1m;
# ssl_session_timeout 5m;
# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
# location / {
# root html;
# index index.html index.htm;
# }
#}
}
Step4 創(chuàng)建nginx鏡像
docker build -t nginx:lnmp .
Step5 運(yùn)行容器
#以nginx容器 在后臺運(yùn)行鏡像
docker run -d --name nginx -p 80:80 -v /opt/nginx/html:/usr/local/nginx/html --net mynetwork --ip 172.18.0.10 nginx:lnmp
- "-d" 表示以后臺運(yùn)行的方式啟動(dòng)容器。
- "--name nginx" 設(shè)置容器的名稱為 "nginx"。
- "-p 80:80" 將主機(jī)的 80 端口映射到容器的 80 端口，使得可以通過主機(jī)的 IP 地址訪問 NGINX 服務(wù)器。
- "-v /opt/nginx/html:/usr/local/nginx/html" 將主機(jī)上的 /opt/nginx/html 目錄與容器內(nèi)的 /usr/local/nginx/html 目錄進(jìn)行掛載，實(shí)現(xiàn)文件共享。
- "--net mynetwork --ip 172.18.0.10" 將容器連接到名為 "mynetwork" 的用戶自定義網(wǎng)絡(luò)，并指定容器的 IP 地址為 172.18.0.10。
- "nginx:lnmp" 指定了要使用的 NGINX 服務(wù)器鏡像和標(biāo)簽。
3）部署Mysql
容器IP 為 172.168.0.20
多階段構(gòu)造
Step1 創(chuàng)建工作目錄
mkdir /opt/mysqld
cd /opt/mysqld
上傳 mysql-boost-5.7.20.tar.gz 到 /opt/mysqld 目錄中
Step2 編寫Dockerfie文件（多階段構(gòu)建）
vim Dockerfile
# 第一階段 - 構(gòu)建階段
FROM centos:7 AS builder
MAINTAINER this is mysql image <byyb>
RUN yum -y install gcc gcc-c++ ncurses ncurses-devel bison cmake make
ADD mysql-boost-5.7.20.tar.gz /usr/local/src/
WORKDIR /usr/local/src/mysql-5.7.20/
RUN cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \
-DSYSCONFDIR=/etc \
-DSYSTEMD_PID_DIR=/usr/local/mysql \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \

-DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DWITH_BOOST=boost \
-DWITH_SYSTEMD=1 && make && make install
# 第二階段 - 配置階段
FROM centos:7 AS config
COPY --from=builder /usr/local/mysql /usr/local/mysql
COPY my.cnf /etc/
ENV PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH
RUN useradd -M -s /sbin/nologin mysql && \
chown mysql:mysql /etc/my.cnf && \
chown -R mysql:mysql /usr/local/mysql/ && \
/usr/local/mysql/bin/mysqld \
--initialize-insecure \
--user=mysql \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data
EXPOSE 3306
CMD ["/usr/local/mysql/bin/mysqld"]
Step3 編寫配置文件
vim my.cnf
[client]
port = 3306
socket = /usr/local/mysql/mysql.sock
[mysql]
port = 3306
socket = /usr/local/mysql/mysql.sock
[mysqld]
user = mysql
basedir = /usr/local/mysql
datadir = /usr/local/mysql/data
port = 3306
character_set_server=utf8
pid-file = /usr/local/mysql/mysqld.pid
socket = /usr/local/mysql/mysql.sock
server-id = 1
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_AUTO_VALUE_ON_ZERO,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,PIPES_AS_CONCAT,ANSI_QUOTES
Step4 創(chuàng)建鏡像
docker build -t mysql:lnmp .
#名稱:標(biāo)簽
Step5 使用新的鏡像運(yùn)行容器并測試
docker run --name=mysql -d --privileged -v /usr/local/mysql --net mynetwork --ip 172.18.0.20 mysql:lnmp
- `--name=mysql`：指定容器的名稱為mysql。
- `-d`：以后臺模式運(yùn)行容器。
- `--privileged`：在容器內(nèi)部啟用特權(quán)模式，可以執(zhí)行一些底層操作。
- `-v /usr/local/mysql`：將宿主機(jī)的`/usr/local/mysql`目錄掛載到容器的相應(yīng)位置。
- `--net mynetwork`：將容器連接到名為mynetwork的網(wǎng)絡(luò)。
4）PHP安裝
容器IP：172.168.0.30
Step1 創(chuàng)建工作目錄并上傳代碼包
mkdir /opt/php
cd /opt/php
上傳 php-7.1.10.tar.bz2 到 /opt/php 目錄中
Step2 編寫相關(guān)配置文件
php-fpm.conf
www.conf
php.ini
Step3 編寫Dockerfile文件
vim Dockerfile
FROM centos:7 AS first
MAINTAINER this is php image <byyb 20231021>
ADD php-7.1.10.tar.bz2 /opt/
RUN yum -y install gd \

useradd -M -s /sbin/nologin nginx && \
rm -rf /var/cache/yum/*
EXPOSE 9000
CMD ["/usr/local/php/sbin/php-fpm", "-F"]
Step4 創(chuàng)建php鏡像
docker build -t php:lnmp .
Step5 運(yùn)行容器
docker run --name=php -d -p 9000:9000 --volumes-from mysql --volumes-from nginx --net mynetwork --ip 172.18.0.30 php:lnmp
5）數(shù)據(jù)庫授權(quán)
docker exec -it mysql /bin/bash
mysql
create database wordpress;
grant all privileges on wordpress.* to 'wordpress'@'%' identified by '123456';
grant all privileges on *.* to 'root'@'%' identified by 'abc123';
flush privileges;
