项目部署流程

项目部署流程

系统更新（centos6.8）

1:更新系统
    yum update -y
2:更新软件
    yum upgrade -y

配置免密登录

1:ssh-****** -t rsa # (本机)
2：vim ~/.ssh/id_rsa.pub # (复制本机公钥)
3：登录服务器  vim ~/.ssh/authorized_keys # (粘贴公钥，服务器)
4: 保存退出断开连接，重新连接

安装软件

安装常用依赖

1:编写脚本:
        install_software() {
            echo '正在安装系统组件...'
            BASIC='man gcc make sudo lsof ssh openssl tree vim language-pack-zh-hans'
            EXT='dnsutils iputils-ping net-tools psmisc sysstat'
            NETWORK='curl telnet traceroute wget'
            LIBS='libbz2-dev libpcre3 libpcre3-dev libreadline-dev libsqlite3-dev libssl-dev zlib1g-dev'
            SOFTWARE='git mysql-server zip p7zip apache2-utils sendmail'
            yum install -y $BASIC $EXT $NETWORK $LIBS $SOFTWARE

            echo '正在清理临时文件'
            yum autoremove
            yum autoclean

            echo '正在设置中文环境'
            locale-gen zh_CN.UTF-8
            export LC_ALL='zh_CN.utf8'
            echo "export LC_ALL='zh_CN.utf8'" >> /etc/bash.bashrc

            echo '正在启动邮件服务'
            service sendmail start

            echo -e '系统组件安装完毕.\n'
        }

安装mysql

1:yum list installed | grep mysql（查看是否安装了mysql）
2:yum -y remove mysql(删除已经安装的mysql,看到complete说明删除成功)
3:yum list | grep mysql(查看mysql版本)
4: yum -y install mysql mysql-server mysql-devel(安装mysql)
5:rpm -qi mysql-server(验证是否安装成功)
6：service mysqld start(启动mysql)
7：mysql -u root(进入mysql)
    如果出现（ERROR 2002 (HY000):）# chown -R openscanner:openscanner /var/lib/mysql
8: use mysql;
    update user set password=password(‘123456‘) where user=‘root‘;
9:GRANT ALL PRIVILEGES ON *.* TO ‘root’@’%’ IDENTIFIED BY ‘你的密码’ WITH GRANT OPTION; 
FLUSH PRIVILEGES;

安装pyenv管理工具

1:安装：
    1:curl -L https://github.com/pyenv/pyenv-installer/raw/master/bin/pyenv-installer | bash
    2: export PATH="$HOME/.pyenv/bin:$PATH"
            eval "$(pyenv init -)"
            eval "$(pyenv virtualenv-init -)" 
    3:pyenv update    
2：配置pyenv:
    cat >> $HOME/.bashrc << EOF
    # PyenvConfig
    export PATH="\$HOME/.pyenv/bin:\$PATH"
    eval "\$(pyenv init -)"
    eval "\$(pyenv virtualenv-init -)"
    EOF
3:配置文件生效
    source $HOME/.bashrc
4：安装python
	pyenv install -v 3.6.7
    pyenv global 3.6.7
5:更新pip工具
    pip install -U pip

安装nginx

1:下载nginx(去官网拷贝地址)
    wget -P /tmp 'http://nginx.org/download/nginx-1.14.1.tar.gz'
2：解压：
	tar -xzf /tmp/nginx-1.14.1.tar.gz -C /tmp
3：安装：
	1：cd /tmp/nginx-1.14.1
    2：./configure
    3：make && make install
    4：cd -
    5：rm -rf /tmp/nginx*
    6：ln -s /usr/local/nginx/sbin/nginx /usr/local/bin/nginx
    

安装redis

1:下载nginx
    wget -P /tmp/ 'http://download.redis.io/releases/redis-5.0.0.tar.gz'
2:解压：
    tar -xzf /tmp/redis-5.0.0.tar.gz -C /tmp
3：安装：
	1：cd /tmp/redis-5.0.0
    2：make && make install
    3：cd -
    4：rm -rf /tmp/redis*

上传代码

1:服务器：
    1:cd /opt/
    2:mkdir -p swiper/logs
2本机：
	1：cd到项目下：
	2:rsync -crvP --exclude={.venv,.git,__pycache__,logs} ./[email protected].X.X.X:/opt/swiper/

创建虚拟环境，安装包

1:创建虚拟环境，cd到项目下
    cd /opt/swiper/
    python -m venv
2:**环境：(注意虚拟环境路径)
    source ./venv/bin/activate
3:按住包：
    pip freeze install -r requirement.txt

项目测试

1:启动项目
    gunicorn -c swiper/gunicorn-config.py swiper.wsgi
2:查看是否启动
	ps aux | grep gunicorn
3:测试：连接状态
    curl http://127.0.0.1:gunicorn配置端口号/请求路径
