1）安裝Mysql數據庫

[root@localhost ~]# rpm -q mysql mysql-server
未安裝軟件包 mysql 
未安裝軟件包 mysql-server 
[root@localhost ~]# yum -y install ncurses-devel
[root@localhost ~]# rpm -q ncurses-devel
ncurses-devel-5.9-14.20130511.el7_4.x86_64

安裝配置工具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
 

創建運行用戶

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

解包，配置，編譯，安裝

[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     //數據庫程序安裝目錄
-DDEFAULT_CHARSET=utf8                  //指定字符集編碼
-DDEFAULT_COLLATION=utf8_general_ci         //默認的字符集校對規則，utf8_general_ci適用於utf-8字符集的通用規則
-DWITH_EXTRA_CHARSETS=all               //指定額外支持的字符集編碼 
-DSYSCONFDIR=/etc                       //指定配置文件存放目錄
 

報錯處理：

----------------------------------------------------------------------------------------------------------------------------
CMake Error at cmake/boost.cmake:81 (MESSAGE):
  You can download it with -DDOWNLOAD_BOOST=1 -DWITH_BOOST=<directory>

  This CMake script will look for boost in <directory>.  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:80

Call 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/CMakeError.log".
----------------------------------------------------------------------------------------------------------------------------
 

解決辦法是：
1.在/usr/local下創建一個名為boost的文件夾

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

2.進入目錄並下載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.解壓boost

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

4.繼續cmake，添加上紅色部分

[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）安裝後的調整
對數據庫目錄進行權限設置

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

建立配置文件(CentOS7系統默認支持MariaDB數據庫，系統默認的/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/data
socket=/tmp/mysql.sock

[mysqld_safe]
log-error=/usr/local/mysql/data/mysql.log
pid-file=/usr/local/mysql/data/mysql.pid

3）初始化數據庫

[root@localhost mysql]# ./bin/mysqld --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --initialize
2018-12-08T01:51:39.798903Z 1 [Note] A temporary password is generated for root@localhost: dskL0)8S3FGe

--basedir=/usr/local/mysql/         //指定安裝目錄（產品目錄）
--datadir=/usr/local/mysql/data     //指定數據目錄
--user=mysql                    //指定用戶身份

4）設置環境變量

[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）添加系統服務
添加MySQL為系統服務，以便通過systemctl命令進行管理

[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 Server
After=network.target

[Service]
User=mysql  #指定程序運行的用戶賬戶
Group=mysql #指定程序運行的組賬戶

Type=forking
PIDFile=/usr/local/mysql/data/localhost.pid #指定PID文件的位置，默認為“主機名.pid”
ExecStart=/usr/local/mysql/bin/mysqld.sh start
ExecStop=/usr/local/mysql/bin/mysqld.sh stop

[Install]
WantedBy=mutil-user.target

[root@localhost ~]# systemctl start mysqld
[root@localhost ~]# systemctl enable mysqld
Created symlink from /etc/systemd/system/mutil-user.target.wants/mysqld.service to /usr/lib/systemd/system/mysqld.service.

[root@localhost ~]# systemctl status mysqld

[root@localhost ~]# netstat -lnpt | grep mysqld

MySQL默認通過TCP3306端口提供服務，可通過編輯/etc/my.cnf文件中"port=3306"行進行修改。
