    第二章、web01搭建博客

    第一步、web01服务器环境配置准备

    确认环境
       netstat -lntup|egrep "80|3306|9000"
    下载上传开源BLOG
       cd /server/tools/
    上传解压
       rz
       unzip wordpress-5.1.1.zip 
    把目录下所有移动到blog站点目录
       mv wordpress/* /application/nginx/html/blog/
    站点目录授权
       chown -R nginx.nginx /application/nginx/html/blog/ 
    查看站点目录属性
       ls -ld /application/nginx/html/blog/
    将博客中动态网页转化成伪静态网页
       if (-f $request_filename/index.html){
            rewrite (.*) $1/index.html break;
        }
        if (-f $request_filename/index.php){
            rewrite (.*) $1/index.php;
        }
        if (!-f $request_filename){
            rewrite (.*) /index.php;
        }
    }

    第二步、打开blog网页安装

    第三章、数据库迁移:从单机LNMP迁移到DB01独立的mysql

    第一步、db01服务器搭建Mysql数据库

    步骤(一键脚本)

    useradd mysql -s /sbin/nologin -M
    id mysql
    cd /server/tools/
    tar xf mysql-5.7.26-linux- glibc2.12-x86_64.tar.gz
    mkdir -p /application
    mv mysql-5.7.26-linux-glibc2.12-x86_64 
    /application/mysql-5.7.26
    ln -s /application/mysql-5.7.26/  /application/mysql
    rpm -e --nodeps mariadb-libs
    cat >/etc/my.cnf<<EOF
    [mysqld]
    basedir = /application/mysql/
    datadir = /application/mysql/data
    socket = /tmp/mysql.sock
    server_id = 1
    port = 3306
    log_error = /application/mysql/data/oldboy_mysql.err
    [mysql]
    socket = /tmp/mysql.sock
    prompt = oldboy [\\d]>
    EOF
    rpm -qa mariadb-libs
    yum install libaio-devel -y
    mkdir -p /application/mysql/data
    chown -R mysql.mysql/application/mysql/
    /application/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/application/mysql/ --datadir=/application/mysql/data
    cat >/etc/systemd/system/mysqld.service<<EOF
    [Unit]
    Description=MySQL Server by oldboy
    Documentation=man:mysqld(8)
    Documentation=http://dev.mysq
    After=network.target
    After=syslog.target
    [Install]
    WantedBy=multi-user.target
    [Service]
    User=mysql
    Group=mysql
    ExecStart=/application/mysql/bin/mysqld --defaults-file=/etc/my.cnf
    LimitNOFILE = 5000
    EOF
    systemctl start mysqld
    systemctl enable mysqld
    netstat -lntup|grep mysql
    echo 'export PATH=/application/mysql/bin:$PATH' >>/etc/profile
    . /etc/profile
    mysql

    第二步、web01服务器停止Mysql服务

    备份:
    mysqldump -uroot -poldboy123 -A -B|gzip >/tmp/web01_db.sql.gz
    拷贝到db01:
    scp /tmp/web01_db.sql.gz 10.0.0.51:/tmp
    停止mysql服务
    systemctl stop mysqld
    systemctl disable mysqld
    lsof -i :3306
    cd /application/nginx/html/blog/
    vim wp-config.php (修改主机名和IP地址)
    
    
    image

    第三步、db01服务器Mysql数据库配置

    检查
        lsof -i :3306
    查看/tmp下文件
        cd /tmp
    解压文件
       gzip -d web01_db.sql.gz 
    把文件里内容输送到mysql数据库
       mysql </tmp/web01_db.sql 
    查看文件里内容
       less web01_db.sql 
    mysql数据库配置
       show databases;
       grant all privileges on wordpress.* to wordpress@'172.16.1.%' identified by 'oldboy123';
       flush privileges;
       select user,authentication_string,host from mysql.user
