MySQL 5.7.21如何在Linux平台中安装Part 2

在本篇文章中，我们将详细介绍如何在Linux平台中安装MySQL 5.7.21，本文分为两个部分，第一部分将介绍在Ubuntu平台上的安装过程，第二部分将介绍在CentOS平台上的安装过程，我们还将提出两个与本文相关的问题并给出解答。

在Ubuntu平台上的安装过程

1、更新系统软件包列表

我们需要更新系统的软件包列表，以确保我们能够获取到最新版本的MySQL，在终端中输入以下命令：

sudo apt-get update

2、安装依赖库

接下来，我们需要安装一些依赖库，这些库将帮助我们编译和运行MySQL，在终端中输入以下命令：

sudo apt-get install build-essential libssl-dev

3、下载MySQL源码包

现在，我们可以开始下载MySQL的源码包了，在终端中输入以下命令：

wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.21.tar.gz

4、解压源码包

下载完成后，我们需要解压源码包，在终端中输入以下命令：

tar -xvf mysql-5.7.21.tar.gz

5、进入解压后的目录

解压完成后，我们需要进入解压后的目录，在终端中输入以下命令：

cd mysql-5.7.21

6、编译并安装MySQL

现在，我们可以开始编译并安装MySQL了，在终端中输入以下命令：

sudo apt-get install libaio1 libmecab2
make all testinstall && sudo make install

7、配置MySQL

编译完成后，我们需要对MySQL进行配置，创建一个名为mysql的数据目录：

sudo mkdir /usr/local/mysql/datadir

编辑MySQL的配置文件：

sudo nano /etc/my.cnf

在配置文件中，添加以下内容：

[mysqld]
basedir=/usr/local/mysql/binlog_basedir_testdb_testtable_testindex_testcharset_testcollation_testtimezone_testsystemvars_testrelaylog_testbinlog_testslave_testgtid_testrelayloginfo_testinnodb_file_per_table_testinnodb_file_per_table_data_home_dir=/usr/local/mysql/datadir/mysqldatahomedir_testdb_testtable_testindex_testcharset_testcollation_testtimezone_testsystemvars_testrelaylog_testbinlog_testslave_testgtid_testrelayloginfo_testinnodb_file_per_table_testinnodb_file_per_table_data_homedir=/usr/local/mysql/datadir/mysqldatahomedir_testdb_testtable_testindex_testcharset_testcollation_testtimezone_testsystemvars_testrelaylog_testbinlog_testslave_testgtid_testrelayloginfo_testinnodb_file_per_table=1 datadir=/usr/local/mysql/datadir log-error=/var/log/mysqld.err socket=/var/run/mysqld/mysqld.sock keyring-file=~/.mylogin.key server-id=1 port=3306 max-connections=200 threads=10 connections=10 wait-timeout=60 time-zone=SYSTEM datadir=/usr/local/mysql/datadir character-set-server=utf8 collation-server=utf8_general_ci init-connect='SET NAMES utf8' connect-timeout=10 local-infile=1 read-default-group-suffix=true sql-mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION client-runtime-hook=mysql57client runtime-hook-type=preexec safe-user-creation=1 secure-file-priv=NULL set-character-set-client=utf8 --defaults-file=/etc/my.cnf skip-external-locking --skip-networking --sysconfile=/etc
