1）安装Mysql数据库

[root@localhost ~]# rpm -q mysql mysql-server未安装软件包 mysql 未安装软件包 mysql-server [root@localhost ~]# yum -y install ncurses-devel[root@localhost ~]# rpm -q ncurses-develncurses-devel-5.9-14.20130511.el7_4.x86_64

安装配置工具cmake

[root@localhost ~]# tar xf cmake-3.13.1.tar.gz -C /usr/src/[root@localhost ~]# cd /usr/src/cmake-3.13.1/[root@localhost cmake-3.13.1]# ./configure && gmake && gmake install

创建运行用户

[root@localhost ~]# useradd -M -s /sbin/nologin mysql

解包，配置，编译，安装

[root@localhost ~]# tar xf mysql-8.0.11.tar.gz -C /usr/src/[root@localhost ~]# cd /usr/src/mysql-8.0.11/[root@localhost mysql-5.7.24]# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_EXTRA_CHARSETS=all -DSYSCONFDIR=/etc && make && make install-DCMAKE_INSTALL_PREFIX=/usr/local/mysql     //数据库程序安装目录-DDEFAULT_CHARSET=utf8                  //指定字符集编码-DDEFAULT_COLLATION=utf8_general_ci         //默认的字符集校对规则，utf8_general_ci适用于utf-8字符集的通用规则-DWITH_EXTRA_CHARSETS=all               //指定额外支持的字符集编码 -DSYSCONFDIR=/etc                       //指定配置文件存放目录

报错处理：

----------------------------------------------------------------------------------------------------------------------------CMake Error at cmake/boost.cmake:81 (MESSAGE):  You can download it with -DDOWNLOAD_BOOST=1 -DWITH_BOOST=
    
       This CMake script will look for boost in 
     
      .  If it is not there,  it will download and unpack it (in that directory) for you.  If you are inside a firewall, you may need to use an http proxy:  export http_proxy=http://example.com:80Call Stack (most recent call first):  cmake/boost.cmake:238 (COULD_NOT_FIND_BOOST)  CMakeLists.txt:507 (INCLUDE)-- Configuring incomplete, errors occurred!See also "/usr/src/mysql-5.7.24/CMakeFiles/CMakeOutput.log".See also "/usr/src/mysql-5.7.24/CMakeFiles/CMakeError.log".----------------------------------------------------------------------------------------------------------------------------
     
    

解决办法是：

1.在/usr/local下创建一个名为boost的文件夹

[root@localhost ~]# mkdir /usr/local/boost

2.进入目录并下载boost

[root@localhost ~]# cd /usr/local/boost[root@localhost boost]# wget https://sourceforge.net/projects/boost/files/boost/1.66.0/boost_1_66_0.tar.gz

3.解压boost

[root@localhost boost]# tar xf boost_1_66_0.tar.gz

4.继续cmake，添加上红色部分

[root@localhost mysql-5.7.24]# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_EXTRA_CHARSETS=all -DSYSCONFDIR=/etc -DWITH_BOOST=/usr/local/boost && make && make install

2）安装后的调整

对数据库目录进行权限设置

[root@localhost ~]# cd /usr/local/mysql/[root@localhost mysql]# chown -R mysql:mysql ./

建立配置文件(CentOS7系统默认支持MariaDB数据库，系统默认的/etc/my.cnf配置文件是MariaDB的配置文件 )

[root@localhost mysql]# vim /etc/my.cnf[mysqld]datadir=/usr/local/mysql/datasocket=/tmp/mysql.sock[mysqld_safe]log-error=/usr/local/mysql/data/mysql.logpid-file=/usr/local/mysql/data/mysql.pid

3）初始化数据库

[root@localhost mysql]# ./bin/mysqld --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --initialize2018-12-08T01:51:39.798903Z 1 [Note] A temporary password is generated for root@localhost: dskL0)8S3FGe--basedir=/usr/local/mysql/         //指定安装目录（产品目录）--datadir=/usr/local/mysql/data     //指定数据目录--user=mysql                    //指定用户身份

4）设置环境变量

[root@localhost mysql-5.7.24]# echo "PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile[root@localhost mysql-5.7.24]# . /etc/profile  =  source /etc/profile

5）添加系统服务

添加MySQL为系统服务，以便通过systemctl命令进行管理

[root@localhost mysql-5.7.24]# cp support-files/mysql.server /usr/local/mysql/bin/mysqld.sh[root@localhost mysql-5.7.24]# chmod +x /usr/local/mysql/bin/mysqld.sh[root@localhost ~]# vim /usr/lib/systemd/system/mysqld.service[Unit]Description=MySQL ServerAfter=network.target[Service]User=mysql  #指定程序运行的用户账户Group=mysql #指定程序运行的组账户Type=forkingPIDFile=/usr/local/mysql/data/localhost.pid #指定PID文件的位置，默认为“主机名.pid”ExecStart=/usr/local/mysql/bin/mysqld.sh startExecStop=/usr/local/mysql/bin/mysqld.sh stop[Install]WantedBy=mutil-user.target[root@localhost ~]# systemctl start mysqld[root@localhost ~]# systemctl enable mysqldCreated symlink from /etc/systemd/system/mutil-user.target.wants/mysqld.service to /usr/lib/systemd/system/mysqld.service.[root@localhost ~]# systemctl status mysqld● mysqld.service - MySQL Server   Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)   Active: active (running) since 六 2018-12-08 09:54:04 CST; 42s ago Main PID: 2520 (mysqld)   CGroup: /system.slice/mysqld.service           ├─2364 /bin/sh /usr/local/mysql/bin/mysqld_safe --datadir=/usr/local/mysql/data --pid...           └─2520 /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=/usr/local/my...12月 08 09:53:57 localhost systemd[1]: Starting MySQL Server...12月 08 09:54:04 localhost systemd[1]: mysqld.service: Supervising process 2520 which is not...ts.12月 08 09:54:04 localhost systemd[1]: Started MySQL Server.12月 08 09:54:16 localhost systemd[1]: mysqld.service: Supervising process 2520 which is not...ts.Hint: Some lines were ellipsized, use -l to show in full.[root@localhost ~]# netstat -lnpt | grep mysqldtcp6       0      0 :::3306                 :::*                    LISTEN      2520/mysqld

MySQL默认通过TCP3306端口提供服务，可通过编辑/etc/my.cnf文件中"port=3306"行进行修改。
