    用户名/密码
    mysql/mysql

     


    一、安装mysql: 位置位于 /data/mysql

    如果遇到依赖,无法删除,使用 rpm -e --nodeps <包的名字> 不检查依赖,直接删除rpm包

    --1.0 查看linux系统版本、环境-------------------------------------------------------


    [root@kangvcar ~]# cat /etc/redhat-release //查看系统的版本
    [root@orcl bayaim]# cat /etc/redhat-release
    CentOS Linux release 7.6.1810 (Core)

    #安装环境
    [root@linux1 Mysql_src]# cat /etc/issue

    防火墙 chkconfig iptables off
    SELINUX
    gedit /etc/sysconfig/selinux
    (本来是:SELINUXTYPE=targeted )
    SELINUX=disabled
    重启reboot
    关闭---快照

    [root@ums-data mysql]# setenforce 0
    setenforce: SELinux is disabled
    [root@ums-data mysql]# getenforce
    Disabled
    [root@ums-data mysql]#


    ---2.0 安装CMAKE-------------------------------------------------------------
    [root@ums-data /]# yum install gcc
    [root@ums-data /]# yum install ncurses-devel

    [root@ums-data /]# tar -zxvf cmake-2.8.5.tar.gz
    [root@ums-data /]# cd cmake-2.8.5
    [root@ums-data /]# ./configure
    [root@UMS-DATA-SLAVE cmake-2.8.5]# make
    [root@UMS-DATA-SLAVE cmake-2.8.5]# make install


    ---3.0-配置 YUM--------------------------------------------------------------
    [root@ums-data /]# vi /etc/resolv.conf
    nameserver 114.114.114.114 (在结尾加上)

    ---CentOS 6
    [root@ums-data /]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
    [root@ums-data /]# yum makecache --生成缓存


    ---4.0-创建mysql用户及用户组------------------------------------------------------------
    [root@ rhel5~]# groupadd mysql

    创建mysql的安装目录及数据库存放目录

    useradd -d /home/mysql -m mysql
    passwd mysql

    [root@bayaim rpm-gpg]# id mysql
    uid=987(mysql) gid=1001(mysql) 组=1001(mysql)

    如果有,请修改:
    [root@tsxs bin]# usermod -s /bin/sh -d /usr/local/mysql -g mysql mysql
    输入密码mysql

    chown -R mysql:mysql /home/mysql
    chmod 755 /home/mysql

    [root@ rhel5~]# mkdir -p /usr/local/mysql //安装mysql
    [root@ rhel5~]# chown -R mysql.mysql /usr/local/mysql/
    [root@ rhel5~]# mkdir -p /data/mysql //存放数据库

    [root@bayaim bay]# mkdir -p /usr/local/mysql/scripts


    [root@ rhel5~]# chown -R mysql.mysql /data/
    [root@ rhel5~]# chown -R mysql.mysql /data/*
    [root@UMS-DATA-SLAVE data]# cd /bai/
    [root@ums-data bai]# tar -zxvf mysql-5.7.22.tar.gz
    [root@UMS-DATA-SLAVE bai]# cd mysql-5.7.22
    [root@UMS-DATA-SLAVE mysql-5.7.22]# ll

    ---5.0-源码编译mysql------------------------------------------------------------

    mysql软件目录: -DCMAKE_INSTALL_PREFIX
    mysql数据目录: -DMYSQL_DATADIR

    [root@UMS-DATA-SLAVE mysql-5.7.22]# time cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/data/mysql/ -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DEXTRA_CHARSETS=all -DENABLED_LOCAL_INFILE=1 -DWITH_BOOST=/usr/local/boost -DMYSQL_UNIX_ADDR=/data/mysql/mysql.sock

    一定记得无报错,才行!!!

    [root@UMS-DATA-SLAVE mysql-5.6.16]# make
    [root@UMS-DATA-SLAVE mysql-5.6.16]# make install
    ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

    ++++++++问题1: 《mysql5.7 必须安装2.9以上的cmake》++++++++
    bash: cmake: 未找到命令...
    tar -xzvf cmake-2.6.4.tar.gz
    cd cmake-2.6.4

    依次执行:
    ./bootstrap
    make
    make install

    ++++++++问题2:+++++++++++++

    mysql5.7.28 安装过程 报错CMake Error at cmake/boost.cmake:81 (MESSAGE)
    CMake Error at cmake/boost.cmake:81 (MESSAGE):
    You can download it with -DDOWNLOAD_BOOST=1 -DWITH_BOOST=

    问题描述:高版本mysql需要boots库的安装才可以正常运行

    解决办法:
    1.在/usr/local下创建一个名为boost的文件夹
    mkdir -p /usr/local/boost
    2.进入这个新创建的文件夹然后下载boost
    wget http://www.sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz
    3.解压
    tar -xvzf boost_1_59_0.tar.gz
    4.继续cmake,添加上红色部分
    即安装后运行:
    因为boost并不需要我们安装,只需要放到指定的目录,在安装mysql的时候,指定boost目录即可,再次我将解压后的文件移动到/usr/local/boost目录中。
    5.然后回到mysql安装。 只需要加上:-DWITH_BOOST=/usr/local/boost 即可

    ++++++++问题3:++++++++++
    CMake Error at cmake/readline.cmake:83(MESSAGE):Curses library not found.

    解决方法:
    安装ncurses-devel:
    yum -y install ncurses-devel(Debian/Ubuntu需安装libncurses5-dev)

    删除mysql解压目录 , 重新执行编译mysql安装

    make[2]: *** [sql/CMakeFiles/sql.dir/item_geofunc_setops.cc.o] 错误 4

    ++++++++问题4:+++++++++++
    make && make install 命令 执行到49% 报 c++: 编译器内部错误:已杀死(程序 cc1plus)
    内存不足,mysql 5.5以上版本编译需要1G以上内存,可以编译安装mysql5.5
    解决方法: linux dd 增加swap 内存

    ++++++++问题5:++++++++++
    [root@bayaim mysql-5.7.22]# yum install ncurses-devel
    Warning: Bison executable not found in PATH
    -- Configuring done
    -- Generating done
    -- Build files have been written to: /software/mysql-5.5.11

    [root@bayaim mysql-5.7.22]# yum install bison

    继续安装:

    [root@bayaim mysql-5.7.22]# make && make install -- 这个安装时间真是JB长。大约半小时呢。XX

    ---6.0-添加环境变量------------------------------------------------------------
    方法一:
    [root@ums-data support-files]# vi /root/.bash_profile
    在PATH=$PATH:$HOME/bin添加参数为:
    PATH=$PATH:$HOME/bin:/usr/local/mysql/bin:/usr/local/mysql/lib
    [root@ rhel5~]#source /root/.bash_profile

    方法二:
    [root@query-db data]# echo 'export PATH=$PATH:/usr/local/mysql/bin' >> /etc/profile
    [root@query-db data]# source /etc/profile

    ---7.0-建立多实例目录------------------------------------------------------------
    [root@UMS-DATA-SLAVE scripts]# pwd
    /usr/local/mysql/scripts ---------这个目录是 make install 系统自动时候建立的
    [root@query-db data]# mkdir -p /data/{mysql3308,mysql3309}
    [root@query-db data]# ll
    [root@query-db data]# mkdir /data/mysql3308/{log,tmp} ##千万不要建/data/ 听网上人瞎写

    更改目录权限
    [root@query-db data]# chown -R mysql:mysql /usr/local/mysql/
    [root@query-db data]# chown -R mysql:mysql /data/
    [root@query-db data]# chown -R mysql:mysql /etc/my.cnf

    ---先,简单的改改---3307同3306---
    [root@orcl mysql3306]# cat my3306.cnf

     

    --8.0-安装数据库------------------------------------------------------------
    --8.1-初始化数据库
    [root@orcl bin]# /usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql

    注意:所以要把data directory文件删除掉再执行,如果删除目录下的文件还是报同样的错,可以试试把目录删除掉,再创建一个,然后授权:

    --8.2-初始化3308/3309数据库

    /usr/local/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql3308/data
    /usr/local/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql3309/data

    注意:1.每次执行都会生成 data/ 文件夹,如果中途失败,就要手动删除!!
    2.这一步执行完,/data/mysql3307/data 下就生成数据库文件了。

    --defaults-file="/data/mysql3306/my3306.cnf"


    修改my.cnf(在一个文件中修改即可)

    [client]
    port=3308
    socket=/data/mysql3308/mysql.sock

    [mysqld_multi]
    mysqld = /usr/local/mysql/bin/mysqld_safe
    mysqladmin = /usr/local/mysql/bin/mysqladmin
    log = /data/mysql/mysqld_multi.log

    [mysqld]
    user=mysql
    basedir = /usr/local/mysql
    sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

    [mysqld3308]

    mysqld=mysqld
    mysqladmin=mysqladmin
    datadir=/data/mysql3308/data
    port=3308
    server_id=3308
    socket=/data/mysql3308/mysql3308.sock
    log-output=file
    slow_query_log = 1
    long_query_time = 1
    slow_query_log_file = /data/mysql3308/log/slow.log
    log-error = /data/mysql3308/log/error.log
    binlog_format = row
    log-bin = /data/mysql3308/log/mysql3308_bin

    [mysqld3309]

    mysqld=mysqld
    mysqladmin=mysqladmin
    datadir=/data/mysql3309/data
    port=3309
    server_id=3309
    socket=/data/mysql3309/mysql3309.sock
    log-output=file
    slow_query_log = 1
    long_query_time = 1
    slow_query_log_file = /data/mysql33079/log/slow.log
    log-error = /data/mysql3309/log/error.log
    binlog_format = row
    log-bin = /data/mysql3309/log/mysql3309_bin


    注意:这种方式,不需要建立log 日志。

     

    7 创建自动启动文件
    # cp /usr/local/mysql/support-files/mysql.server /etc/rc.d/init.d/mysqld3306
    [root@query-db init.d]# vi /etc/rc.d/init.d/mysqld3307

    [root@query-db init.d]# service mysqld3307 restart


    --9.0-启动mysql数据库------------------------------------------------------------

    分配独立配置文件

    #配置文件优先级,/etc/与basedir目录下不要存在my.cnf配置文件

    /etc/my.cnf >basedir/my.cnf >datadir/my.cnf

    /usr/local/mysql/bin/mysqld_safe --defaults-file=/data/mysql3306/my3306.cnf --user=mysql & //启动MySQL,但不能停止


    mysql --socket=/data/mysql3306/mysql.sock -uroot -proot
    回车,直接进去mysql

     

    2.14.mysqld_multi进行多实例管理

    启动全部实例:[root@mysql ~]# /usr/local/mysql/bin/mysqld_multi start
    关闭全部实例: [root@mysql ~]# /usr/local/mysql/bin/mysqld_multi report

    查看全部实例状态:/usr/local/mysql/bin/mysqld_multi report
    启动单个实例:/usr/local/mysql/bin/mysqld_multi start 3306
    停止单个实例:/usr/local/mysql/bin/mysqld_multi stop 3306
    查看单个实例状态:/usr/local/mysql/bin/mysqld_multi report 3306


    [root@test4 ~]# /usr/local/mysql/bin/mysqld_multi --defaults-file=/etc/my.cnf start 3308

    启动mysql服务器:./mysqld_multi --defaults-file=/etc/my.cnf start 3306-3307
    关闭mysql服务器: mysqladmin shutdown


    (2)启动多实例
    [root@test4 ~]# /usr/local/mysql/bin/mysqld_multi --defaults-file=/etc/my.cnf start 3308
    [root@test4 ~]# mysqld_multi --defaults-extra-file=/etc/my.cnf stop 1,2,3
    --------------------------------------------

    [root@oradata mysql3308]# mysql -h127.0.0.1 -P 3308 -uroot -p
    [root@oradata mysql3308]# mysql --socket=/data/mysql_3306/data/mysql_3306.sock
    [root@oradata mysql3308]# mysql -S /data/mysql_3306/data/mysql_3306.sock

    [root@query-db data]# mysql --socket=/data/mysql_3306/data/mysql_3306.sock -uroot -proot
    [root@query-db data]# mysql --socket=/data/mysql_3307/data/mysql_3307.sock -uroot -proot

    mysql --socket=/data/mysql3308/mysql3308.sock -uroot -p
    mysql --socket=/data/mysql3308/mysql3308.sock -uroot -prootBPY123.#

    mysql --socket=/data/mysql3309/mysql3309.sock -uroot -p
    mysql --socket=/data/mysql3309/mysql3309.sock -uroot -prootBPY123.#

    [root@orcl data]# mysql -h127.0.0.1 -P 3308 -uroot -p
    [root@orcl data]# mysql --socket=/data/mysql3308/mysql3308.sock -uroot -prootBPY123.# -hlocalhost

     


    修改3307实例密码:
    # /usr/local/mysql/bin/mysqladmin -u root password 'root' -S /data/mysql_3308/data/mysql_3308.sock #设置管理员密码


    5. 关闭mysql多实例方式
    # /usr/local/mysql/bin/mysqladmin -u root -p -P 3306 -S /data/mysql_3306/mysql_3306.sock shutdown
    # /usr/local/mysql/bin/mysqladmin -u root -p -P 3307 -S /data/mysql_3307/data/mysql_3307.sock shutdown
    # /usr/local/mysql/bin/mysqladmin -u root -p -P 3308 -S /data/mysql_3308/data/mysql_3308.sock shutdown

    [root@orcl data]# mysqladmin shutdown --socket=/data/mysql3308/mysql3308.sock -uroot -prootBPY123.# -hlocalhost
    [root@orcl data]# mysqladmin shutdown --socket=/data/mysql3309/mysql3309.sock -uroot -prootBPY123.# -hlocalhost


    或采用kill方式,或编

     


    查看端口:

    [root@oradata ~]# lsof -i :3306
    [root@oradata ~]# netstat -lnt|grep 330

     


    --10.0-修改mysql密码------------------------------------------------------------

    --10.1-登录
    修改MySQL的root用户的密码以及打开远程连接

    [root@UMS-DATA-SLAVE mysql]# mysql -uroot -p
    Enter password:
    回车
    直接进去

    --10.2-修改密码
    MySQL5.7 加强了安全保障,以上意思是密码不符合安全策略要求,我们输入一个8位或以上长度,复杂一点的密码,比如:

    mysql>use mysql;
    mysql>desc user;
    mysql>GRANT ALL PRIVILEGES ON *.* TO root@'%' IDENTIFIED BY 'rootBPY123.#' WITH GRANT OPTION;
    mysql>update mysql.user set authentication_string=password('rootBPY123.#') where user='root' ;
    mysql> select Host,User from user where User='root';

    删除空用户
    mysql>DELETE FROM mysql.user WHERE user='';
    mysql>flush privileges;
    mysql>exit
