本次安裝操做在騰訊雲上實現（版本：CentOS Linux release 7.4.1708 (Core) ）。html
根據教程實現（中途各類挖坑，填坑。。。），地址：http://www.runoob.com/linux/mysql-install-setup.html mysql

MySQL 安裝
1、安裝編譯工具及庫文件
c++
yum -y install gcc gcc-c++ make autoconf libtool-ltdl-devel gd-devel freetype-devel libxml2-devel libjpeg-devel libpng-devel openssl-devel curl-devel bison patch unzip libmcrypt-devel libmhash-devel ncurses-devel sudo bzip2 flex libaio-develweb
2、 安裝cmake 編譯器sql
cmake 版本：cmake-3.1.1。數據庫
一、下載地址：http://www.cmake.org/files/v3.1/cmake-3.1.1.tar.gzbootstrap
$ wget http://www.cmake.org/files/v3.1/cmake-3.1.1.tar.gz服務器
二、解壓安裝包curl
$ tar zxvf cmake-3.1.1.tar.gz
三、進入安裝包目錄
$ cd cmake-3.1.1
四、編譯安裝
$ ./bootstrap $ make && make install
3、安裝 MySQL
MySQL版本：mysql-5.6.15。
一、下載地址： http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.15.tar.gz
本人下載安裝包路徑：/usr/local （嚴重影響之後各配置路徑）
$ wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.15.tar.gz
二、解壓安裝包
$ tar zxvf mysql-5.6.15.tar.gz
三、進入安裝包目錄
$ cd mysql-5.6.15
四、編譯安裝
$ cmake -DCMAKE_INSTALL_PREFIX=/usr/local/webserver/mysql/ -DMYSQL_UNIX_ADDR=/tmp/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_EXTRA_CHARSETS=all -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DWITH_INNODB_MEMCACHED=1 -DWITH_DEBUG=OFF -DWITH_ZLIB=bundled -DENABLED_LOCAL_INFILE=1 -DENABLED_PROFILING=ON -DMYSQL_MAINTAINER_MODE=OFF -DMYSQL_DATADIR=/usr/local/webserver/mysql/data -DMYSQL_TCP_PORT=3306 $ make && make install
五、查看mysql版本:
$ /usr/local/webserver/mysql/bin/mysql --version
MySQL 配置
一、建立mysql運行使用的用戶mysql：
$ /usr/sbin/groupadd mysql $ /usr/sbin/useradd -g mysql mysql
二、建立binlog和庫的存儲路徑並賦予mysql用戶權限
$ mkdir -p /usr/local/webserver/mysql/binlog /www/data_mysql $ chown mysql.mysql /usr/local/webserver/mysql/binlog/ /www/data_mysql/
三、建立my.cnf配置文件
將/etc/my.cnf替換爲下面內容
（建議將原文件重命名，再新建立這個名字的文件，將下面內容粘貼進去，其中datadir 是數據庫存放的位置，默認/var/lib/mysql）
[client]
port = 3306
socket = /tmp/mysql.sock
[mysqld]
replicate-ignore-db = mysql

四、初始化數據庫
$/usr/local/webserver/mysql/scripts/mysql_install_db --defaults-file=/etc/my.cnf --user=mysql
上面語法報錯FATAL ERROR: Could not find ./bin/my_print_defaults
問題緣由：操做時絕對路徑下找不到該文件，改爲相對路徑下執行
解決方法：切換到安裝目錄路徑（/usr/local/webserver/mysql）下執行
./scripts/mysql_install_db --defaults-file=/etc/my.cnf --user=mysql
五、建立開機啓動腳本
$ cd /usr/local/webserver/mysql/ $ cp support-files/mysql.server /etc/rc.d/init.d/mysqld $ chkconfig --add mysqld $ chkconfig --level 35 mysqld on
六、啓動mysql服務器
$ service mysqld start
上面語法報錯 The server quit without updating PID file (/usr/local/webserver/mysql/mysql.pid).
問題緣由：查看路徑下沒有文件mysql.pid，mysql全部者是root，mysql用戶沒有建立權限
解決方法：將mysql文件夾下的全部者給mysql，chown -R mysql:mysql mysql
七、鏈接 MySQL
$ /usr/local/webserver/mysql/bin/mysql -u root -p
root用戶下沒有密碼，或者直接su mysql 進入
客戶端鏈接服務器
使用Navicat鏈接mysql時報錯，主機不容許鏈接服務器。
1.鏈接MySQL
$ /usr/local/webserver/mysql/bin/mysql -u root -p
2.設置鏈接信息
用戶：mysql使用密碼：mypassword從任何主機鏈接到mysql服務器
GRANT ALL PRIVILEGES ON *.* TO 'mysql'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
若是你想容許用戶myuser從ip爲192.168.2.3的主機鏈接到mysql服務器，並使用mypassword做爲密碼
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.2.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
其餘命令
- 啓動：service mysqld start
- 中止：service mysqld stop
- 重啓：service mysqld restart
- 重載配置：service mysqld reload
- 查看進程 ps -elf | grep mysqld
