docker部署环境相关

搞后台的小伙伴应该都知道，我们部署测试环境或者生产环境都需要经常去下载安装各种环境，原生安装超级耗时！这时候就可以用docker来安装mysql、redis这些了(如果公司用K8S的话，这个就不用看了~)

安装docker

#安装必要的一些系统工具
yum install -y yum-utils
#添加软件源信息
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
#安装Docker
yum install docker-ce docker-ce-cli containerd.io
#开启Docker服务
systemctl start docker

安装mysql

#docker安装mysql
docker run -d -e MYSQL_ROOT_PASSWORD=123456 --name mysql5.7 --restart always -v /usr/local/dockerData/mysql/data:/var/lib/mysql -v /usr/local/dockerData/mysql/logs:/logs -v /usr/local/dockerData/mysql/conf:/etc/mysql -e TZ=Asia/Shanghai -p 3306:3306 mysql:5.7

#查看mysql容器id
docker ps 

#进入容器  62349aa31687为容器id
docker exec -it 62349aa31687 /bin/bash

#登录mysql
mysql -uroot -p12345

#授权：
GRANT ALL ON *.* TO 'root'@'%';

#刷新权限：
flush privileges;

#更新加密规则：
ALTER USER 'root'@'localhost' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER;

#更新root用户密码：
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';

#刷新权限：
flush privileges;

#退出mysql
exit;

#退出容器
exit;

#mysql5.7默认情况下启动了 ONLY_FULL_GROUP_BY 模式
#因此需要在挂载的conf目录下新建my.cnf
cd /usr/local/dockerData/mysql/conf

vi my.cnf
#写入配置信息

[mysqld]
default-storage-engine=INNODB
character-set-server=utf8
collation-server=utf8_general_ci
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# Settings user and group are ignored when systemd is used.
# If you need to run mysqld under a different user or group,
# customize your systemd unit file for mariadb according to the
# instructions in http://fedoraproject.org/wiki/Systemd

#重启mysql容器
docker restart 62349aa31687

安装redis

#docker安装redis
#开启数据持久化 --appendonly yes
docker run -d --privileged=true -p 6379:6379 --restart always -v /usr/local/dockerData/redis/conf:/etc/redis -v /usr/local/dockerData/redis/data:/data --name myredis redis:5.0-alpine redis-server /etc/redis/redis.conf --appendonly yes

安装rabbitmq

#docker安装rabbitmq
docker run -d --restart always -p 5672:5672 -p 15672:15672 --name rabbitmq -v /usr/local/rabbitmq/data:/var/lib/rabbitmq -e RABBITMQ_DEFAULT_USER=guest -e RABBITMQ_DEFAULT_PASS=guest rabbitmq:3.7.7-management

安装nginx

#在将要挂载的ng配置文件的目录下先创建配置
#/usr/local/dockerData/nginx/conf
cd /usr/local/dockerData/nginx/conf

#创建配置
vi nginx.conf

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


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"';

    access_log  /var/log/nginx/access.log  main;
    sendfile        on;
    #tcp_nopush     on;
    keepalive_timeout  65;
    #gzip  on;
    include /etc/nginx/conf.d/*.conf;
}



#启动nginx
docker run -d -p 80:80 --name mynginx --restart=always --privileged=true -v /usr/local/dockerData/nginx/conf/nginx.conf:/etc/nginx/nging.conf nginx:1.16.1
