• MySQL运维---源码安装


    一、二进制安装Mysql

      1、下载mysql-5.6.40源码文件  

    wget https://mirrors.sohu.com/mysql/MySQL-5.6/mysql-5.6.40.tar.gz

      2、安装epel源

    wget -O /etc/yum.repos.d/epel.repo https://mirrors.aliyun.com/repo/epel-7.repo

      3、安装依赖包

    yum install -y ncurses-devel libaio-devel
    yum install -y gcc-c++ gcc glibc

      4、安装cmake

    yum install -y cmake

      5、创建mysql用户,不允许登录,不设置家目录

    useradd mysql -s /sbin/nologin -M

      6、修改hosts映射

    [root@computer ~]# vi /etc/hosts
    
    127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
    ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
    10.0.0.31   computer

      7、解压源码包

    [root@computer ~]# tar -zxvf mysql-5.6.40.tar.gz

      8、创建安装目录

    [root@computer ~]# mkdir /application

      9、进入目录

    cd mysql-5.6.40

      10、生成

    cmake . -DCMAKE_INSTALL_PREFIX=/application/mysql-5.5.40 
    -DMYSQL_DATADIR=/application/mysql-5.5.40/data 
    -DMYSQL_UNIX_ADDR=/application/mysql-5.5.40/tmp/mysql.sock 
    -DDEFAULT_CHARSET=utf8 
    -DDEFAULT_COLLATION=utf8_general_ci 
    -DWITH_EXTRA_CHARSETS=all 
    -DWITH_INNOBASE_STORAGE_ENGINE=1 
    -DWITH_FEDERATED_STORAGE_ENGINE=1 
    -DWITH_BLACKHOLE_STORAGE_ENGINE=1 
    -DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 
    -DWITH_ZLIB=bundled 
    -DWITH_SSL=bundled 
    -DENABLED_LOCAL_INFILE=1 
    -DWITH_EMBEDDED_SERVER=1 
    -DENABLE_DOWNLOADS=1 
    -DWITH_DEBUG=0

           

      

      生成完成

      

       11、编译

    [root@computer mysql-5.6.40]# make

       编译完成

      

       12、安装

    [root@computer mysql-5.6.40]# make install

      安装完成

      

       13、创建软链接

    [root@computer mysql-5.6.40]# ln -s /application/mysql-5.5.40/ /application/mysql

      14、拷贝配置文件

    [root@computer mysql-5.6.40]# cp support-files/my*.cnf /etc/my.cnf
    cp:是否覆盖"/etc/my.cnf"? y

      15、拷贝mysql启动脚本

    [root@computer mysql-5.6.40]# cp support-files/mysql.server /etc/init.d/mysqld

      16、进入Mysql初始化脚本目录

    [root@computer mysql-5.6.40]# cd /application/mysql/scripts/
    [root@computer scripts]# yum install autoconf -y 安装依赖包

      17、初始化Mysql

    [root@computer scripts]# ./mysql_install_db --user=mysql --basedir=/application/mysql --datadir=/application/mysql/data

      初始化完成

      

       18、授权

    [root@computer scripts]# chown -R mysql.mysql /application/mysql

      19、给启动脚本授700权限

    [root@computer scripts]# chmod 700 /etc/init.d/mysqld

       20、systemd管理MySQL启动

    [root@computer scripts]# vim /usr/lib/systemd/system/mysqld.service
    [Unit]
    Description=MySQL server
    Documentation=man:mysql(8)
    Documentation=https://dev.mysql.com/doc/refman/en/using-systemd.html
    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
    [root@computer ~]# systemctl daemon-reload 重新加载一下

      21、设置开机自启

    [root@computer scripts]# chkconfig mysqld on                        centos6设置开机自启
    [root@computer scripts]# systemctl enable mysqld centos7设置开机自启

      22、启动mysql服务

    [root@computer scripts]# mkdir /application/mysql-5.5.40/tmp         创建目录
    [root@computer scripts]# /etc/init.d/mysqld start centos6启动服务
    [root@computer scripts]# systemctl start mysqld centos7启动服务

      报错1:

      

      报错原因:msyql找不到PID文件,Mysql启动不成功,肯定找不到PID文件

      解决办法:授权

    [root@computer support-files]# chown -R mysql.mysql /application/mysql*

      报错2:

      

         报错原因:没有做初始化

      解决办法:去做初始化

      报错3:

      

       报错原因:socket文件已经存在

      解决办法:删除socket文件

      报错4:

      

       报错原因:socket存放目录权限被拒绝

      解决办法:给socket存放目录授权

    [root@computer support-files]# chown -R mysql.mysql /application/mysql/tmp/

      启动成功:

           

      23、添加环境变量

    [root@computer mysql]# echo 'PATH=/application/mysql/bin/:$PATH' >>/etc/profile
    个人推荐
    [root@computer mysql]# echo 'PATH=/application/mysql/bin/:$PATH' >/etc/profile.d/mysql.sh

      24、重新加载环境变量

    [root@computer mysql]# source /etc/profile

       25、登录msyql

    [root@computer mysql]# mysql
    Welcome to the MySQL monitor.  Commands end with ; or g.

    [root@computer mysql]# mysql -uroot -p123456 -h127.0.0.1                     Mysql登录

      26、基本命令操作
