1.6 配置镜像加速
这里使用的是阿里云镜像加速，选择镜像加速器，地址：
https://cr.console.aliyun.com/cn-hangzhou/mirrors
[root@wldev08 ~]# mkdir -p /etc/docker
[root@wldev08 ~]# tee /etc/docker/daemon.json <<-'EOF'
> {
> "registry-mirrors": ["https://b3z80jv9.mirror.aliyuncs.com"]
> }
> EOF
{
"registry-mirrors": ["https://b3z80jv9.mirror.aliyuncs.com"]
}
[root@wldev08 ~]# systemctl daemon-reload
[root@wldev08 ~]# systemctl restart docker
或者
vim /etc/docker/daemon.json
{
"registry-mirrors": ["https://68rmyzg7.mirror.aliyuncs.com"]

- 容器后台与前台运行
- ctrl+P,Q 切换至后台运行
attach 可以将容器调用到前台
- 死循环方式 如sleep 100000
- 让程序前台一直运行(夯在前台)
制作守护式容器时，常用的方法
4. docker容器网络访问
- 指定映射(docker 会自动添加一条iptables规则来实现端口映射)
-p hostPort:containerPort
-p ip:hostPort:containerPort
-p ip::containerPort(随机端口:32768-60999)
-p hostPort:containerPort/udp
-p 81:80 –p 443:443 // 多端口映射
如：
[root@docker ~]# docker container run -d -p 8080:80 --name='n2' nginx:1.14
[root@docker ~]# docker container run -d -p 10.0.0.100:8081:80 --name='n3' nginx:1.14
- 随机映射
docker run -P 80（随机端口）
[root@docker ~]# docker container run -d -p 80 --name='n5' nginx:1.14
[root@docker ~]# docker container run -d -p 172.16.1.200::80 --name='n6' nginx:1.14
- 查看映射端口
[root@wldev08 ~]# docker container port 70a62f1987e0
80/tcp -> 0.0.0.0:8080
[root@wldev08 ~]# docker port 70a62f1987e0
80/tcp -> 0.0.0.0:8080
[root@wldev08 ~]#
5. 容器其他管理
- 查看所有容器ID
[root@wldev08 ~]# docker container ls -a -q
70a62f1987e0
e57937d57ac0
2117378dd5cd
[root@wldev08 ~]# docker ps -a -q
70a62f1987e0
e57937d57ac0
2117378dd5cd
[root@wldev08 ~]#
- 查看容器的进程信息
[root@wldev08 ~]# docker container top 70a62f1987e0
UID PID PPID C STIME TTY TIME CMD
root 13209 13194 0 10月30 ? 00:00:00 nginx: master process nginx -g daemon off;
101 13240 13209 0 10月30 ? 00:00:00 nginx: worker process
[root@wldev08 ~]# docker top 70a62f1987e0
UID PID PPID C STIME TTY TIME CMD
root 13209 13194 0 10月30 ? 00:00:00 nginx: master process nginx -g daemon off;
101 13240 13209 0 10月30 ? 00:00:00 nginx: worker process
[root@wldev08 ~]#
- 查看日志
[root@oldboy docker]# docker logs testxx
[root@oldboy docker]# docker logs -tf testxx
[root@oldboy docker]# docker logs -t testxx
[root@oldboy docker]# docker logs -tf --tail 10 testxx
[root@oldboy docker]# docker logs -tf --tail 0 testxx
6. Docker数据卷实现持久化存储
6.1 手工交互数据
[root@docker opt]# docker container cp index.html n1:/usr/share/nginx/html/
将/opt/目录下的index.html拷贝到容器
[root@docker opt]# docker container cp n1:/usr/share/nginx/html/50x.html ./
将容器里的html拷贝到当前目录
6.2 Volume实现宿主机和容器的数据共享
[root@docker opt]# mkdir -p /opt/html
[root@docker ~]# docker run -d --name="nginx_3" -p 83:80 -v /opt/html:/usr/share/nginx/html nginx
类似与软连接形式，作用: 数据持久化
6.3 数据卷容器
- 宿主机创建数据目录
[root@wldev08 ~]# mkdir -p /opt/Volume/a
[root@wldev08 ~]# mkdir -p /opt/Volume/b
[root@wldev08 ~]# touch /opt/Volume/a/a.txt
[root@wldev08 ~]# touch /opt/Volume/b/b.txt
[root@wldev08 ~]# tree /opt/Volume/
/opt/Volume/
├── a
│ └── a.txt
└── b
└── b.txt
2 directories, 2 files
[root@wldev08 ~]#
- 启动数据卷容器
[root@wldev08 ~]# docker image ls
REPOSITORY TAG IMAGE ID CREATED SIZE
nginx v2 540a289bab6c 8 days ago 126MB
nginx 1.14 295c7be07902 7 months ago 109MB
centos 6.9 2199b8eb8390 7 months ago 195MB
centos 7.5.1804 cf49811e3cdb 7 months ago 200MB
[root@wldev08 ~]# docker run -it --name="nginx_volumes" -v /opt/Volume/a:/opt/a -v /opt/Volume/b:/opt/b centos:6.9 /bin/bash
[root@3a5b7e9c3714 /]#
此处不能直接退出，否则容器会直接关闭
ctrl+p,q
- 使用数据卷容器
[root@wldev08 ~]# docker container ls
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
3895eac17824 nginx "nginx -g 'daemon of…" About an hour ago Up About an hour 0.0.0.0:8086->80/tcp nginx_8086
8b38eef11715 nginx "nginx -g 'daemon of…" About an hour ago Up About an hour 0.0.0.0:8085->80/tcp nginx_8085
ce66cc9aebda centos:6.9 "/bin/bash" About an hour ago Up About an hour nginx_volumes
[root@wldev08 ~]#
[root@wldev08 ~]# docker container exec -it nginx_8085 /bin/bash
root@8b38eef11715:/# ls /opt/a/
a.txt
root@8b38eef11715:/# ls /opt/b/
b.txt
作用: 在集中管理集群中,大批量的容器都需要挂载相同的多个数据卷时,可以采用数卷容器进行统一管理
7. 构建本地yum源
7.1 安装vsftpd服务
[root@wldev08 ~]# yum -y install vsftpd
[root@wldev08 ~]# rpm -qa |grep vsftpd
vsftpd-3.0.2-25.el7.x86_64
[root@wldev08 ~]# systemctl enable vsftpd
Created symlink from /etc/systemd/system/multi-user.target.wants/vsftpd.service to /usr/lib/systemd/system/vsftpd.service.
[root@wldev08 ~]# systemctl start vsftpd
[root@wldev08 ~]# ps -ef |grep vsftpd
root 28778 1 0 11:14 ? 00:00:00 /usr/sbin/vsftpd /etc/vsftpd/vsftpd.conf
root 28780 28190 0 11:14 pts/0 00:00:00 grep --color=auto vsftpd
[root@wldev08 ~]#
7.2 配置Yum仓库
[root@wldev08 ~]# mkdir -p /var/ftp/centos7.3
[root@wldev08 ~]# mkdir -p /var/ftp/centos6.8

[root@wldev08 ~]#
[root@wldev08 mnt]# mount -o loop /mnt/CentOS-7-x86_64-DVD-1611.iso /var/ftp/centos7.3/
mount: /dev/loop0 写保护，将以只读方式挂载
[root@wldev08 mnt]# mount -o loop /mnt/CentOS-6.8-x86_64-bin-DVD1.iso /var/ftp/centos6.8/
mount: /dev/loop1 写保护，将以只读方式挂载
[root@wldev08 mnt]#
开机自启动挂载
[root@wldev08 ~]# cat /etc/rc.local |grep -v "^#"
touch /var/lock/subsys/local
mount -o loop /mnt/CentOS-7-x86_64-DVD-1611.iso /var/ftp/centos7.3/
mount -o loop /mnt/CentOS-6.8-x86_64-bin-DVD1.iso /var/ftp/centos6.8/
[root@wldev08 ~]#
[root@wldev08 ~]# sh /etc/rc.local
mount: /mnt/CentOS-7-x86_64-DVD-1611.iso 已经挂载
mount: /mnt/CentOS-6.8-x86_64-bin-DVD1.iso 已经挂载
[root@wldev08 ~]#
7.3 ssh登录容器
[root@wldev08 ~]# docker attach ce66cc9aebda
[root@ce66cc9aebda /]# yum clean all
[root@ce66cc9aebda /]# yum -y install openssh*
[root@ce66cc9aebda /]# service sshd start
Generating SSH2 RSA host key: [ OK ]
Generating SSH1 RSA host key: [ OK ]
Generating SSH2 DSA host key: [ OK ]
Starting sshd: [ OK ]
设置密码后，即可使用ssh登录容器
8. 镜像制作

yum makecache fast && yum install openssh-server -y
/etc/init.d/sshd start ----->重要:ssh第一次启动时,需要生成秘钥,生成pam验证配置文件

Initializing MySQL database: Installing MySQL system tables...
OK
Filling help tables...
OK
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h 55e135461eb5 password 'new-password'
Alternatively you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd /usr/mysql-test ; perl mysql-test-run.pl
Please report any problems with the /usr/bin/mysqlbug script!

10. 镜像制作dockerfile
10.1 dockerfile常用指令
FROM： 基础镜像
Syntax：
FROM centos:6.9
FROM centos@2199b8eb8390
RUN： 构建镜像过程中运行的命令
Syntax：
RUN mv /etc/yum.repos.d/*.repo /tmp && echo -e "[ftp]\nname=ftp\nbaseurl=ftp://172.17.0.1/centos6.9\ngpgcheck
=0">/etc/yum.repos.d/ftp.repo && yum makecache fast && yum install openssh-server -y
RUN ["mysqld","--initialize-insecure","--user=mysql" ,"--basedir=/usr/local/mysql","--datadir=/data/mysql/data"]
EXPOSE: 向外暴露的端口,多个写多行即可
Syntax:
EXPOSE 22
CMD 使用镜像启动容器时运行的命令
Syntax：
CMD ["/usr/sbin/sshd","-D"]
10.2 dockerfile基本制作
[root@wldev08 ~]# mkdir -p /opt/dockfile/centos6.9_ssh
[root@wldev08 ~]# cat /opt/dockfile/centos6.9_ssh/dokerfile

RUN /etc/init.d/sshd start && /etc/init.d/sshd stop && echo "123456" | passwd root --stdin

10.4 copy命令和add命令解释
COPY命令：
Syntax：
<src>... <dest>
从dockerfile所在目录，拷贝目标文件到容器的制定目录下。
可以支持统配符，如果拷贝的是目录，只拷贝目录下的子文件子目录。
cp oldguo/*
ADD
Syntax：
<src>... <dest>
url <dest>
比COPY命令多的功能是，可以自动解压.tar*的软件包到目标目录下
可以指定源文件为URL地
VOLUME ["<mountpoint>"]
<src>... <dest>
/home/data /home/data
使容器中的一个目录具有持久化存储数据的功能，该目录可以被容器本身使用，也可以共享给其他容器使用
WORKDIR
ENV 设定变量
ENV CODEDIR /var/www/html/
ENV DATADIR /data/mysql/data
ADD bbs.tar.gz ${CODEDIR}
VOLUME ["${CODEDIR}","${DATADIR}"]
ENTRYPOINT
#CMD ["/bin/bash","/init.sh"]
ENTRYPOINT ["/bin/bash","/init.sh"]
说明：
ENTRYPOINT 可以方式，在启动容器时，第一进程被手工输入的命令替换掉，防止容器秒起秒关

14.4 docker 跨主机访问-overlay实现
overlay网络利用隧道技术，将数据包封装到UDP中进行传输。因为涉及数据包的封装解封，存在额外的cpu和网络开销
overlay较underlay可以支持更多的二层网络，更好的利用已有网络，以及有效的避免物理交换机MAC表耗尽等优势
- 启动 consul 服务,实现网络的统一配置管理

系统性能优化篇_软件系统 性能优化文档-程序员宅基地
文章浏览阅读203次。实际工作中,需要根据系统的业务场景和瓶颈来选择和实施合适的优化方案,这需要架构师的经验和技巧。选用合适的Web服务器:Web服务器的性能会直接影响应用服务的吞吐量和响应时间,常用的有Nginx、Apache、Tomcat等。减少外部访问:使用缓存可以减少对外部存储系统如数据库的访问,特别是在高并发场景下,可以大大降低外部存储的压力,提高系统的整体性能和可扩展性。尽量考虑并发用户场景下的测试。选择合适的算法和数据结构:这是性能优化的基础,例如用哈希表实现O(1)的查询,用堆排序实现O(nlogn)的排序等。_软件系统 性能优化文档
