Mysql Series II: CentOS 7.4 installation of mysql5.7.28 source code

Keywords: MySQL vim yum OpenSSL

This article is the blog Mysql Series II: CentOS 7.4 install Mysql 5.7.28 source code

There are many ways to install mysql. Take Centos7 as an example, you can download the compiled binary code on the official website for installation, and you can download the rpm package on the official website for installation. In this paper, we introduce the self compilation and installation of the download source code on the official website.

According to the source code downloaded from MySQL series I, we started to install MySQL source code. We hope that you can read more about the installation method from the document on the official website and learn the essence. The installation method and order are not unique. The following content is for reference.

Basic environment:

yum install -y ntp wget curl lrzsz vim sysstat iftop pcre pcre-devel openssl openssl-devel

Compile installation environment:

yum -y install wget gcc gcc-c++ cmake openssl-devel ncurses-devel zlib-devel

Download and decompress on the official website:

mysql-5.7.28.tar.gz and mysql-boost-5.7.28.tar.gz
cd /data/app_install/package
 tar zxvf mysql-5.7.28.tar.gz 
mkdir mysql-boost
tar zxvf mysql-boost-5.7.28.tar.gz -C mysql-boost

Create mysql user:

groupadd mysql 
useradd  -g mysql -s /sbin/nologin -d /data/app_install/mysql_3306 mysql

Create mysql related directory:

MKDIR - P / data / logs / MySQL
 MKDIR - P / data / app? Install / MySQL? Install directory
 MKDIR - P / data / app? Install / MySQL? 3306 / conf my.cnf configuration file directory
 MKDIR - P / data / APP ﹐ install / MySQL ﹐ 3306 / tmp mysql.sock directory
 MKDIR - P / data / data / data? MySQL database file directory

Compile configuration:

cmake . 
-DDEFAULT_CHARSET=utf8mb4 -DDEFAULT_COLLATION=utf8mb4_general_ci 




make install

Startup file:

cp /data/app_install/mysql_3306/support-files/mysql.server /etc/init.d/mysqld


chown -R mysql:mysql /data/app_install/mysql_3306/
chown -R mysql:mysql /data/data/data_mysql/
chown -R mysql:mysql /data/logs/mysql_3306/

Environment variable:

mkdir /data/env
cd /data/env
vim mysql.env
export PATH=$PATH:/data/app_install/mysql_3306/bin
vim /etc/profile
source /data/env/mysql.env

Initialize database:
– initialize means that a random security password is generated by default, – initialize execute means that no password is generated, and you do not want to find and use random password in the log. You can initialize it in the following way, and then set the password in the security initialization boot

mysqld --defaults-file=/data/app_install/mysql_3306/conf/my.cnf --user=mysql --initialize-insecure

Start mysql:

/etc/init.d/mysqld start

When starting, if there is no log path or permission problem, re create and assign mysql:mysql permission. At the same time, if there is a Starting MySQL. ERROR! The server quit without updating PID file (/data/app_install/mysql_3306/, it is also a permission problem. All involved directory files need mysql:mysql permission except the startup file
Try to log in:

Login without password

Security initialization boot:
When using this function, the mysql process needs to be online, and use the mysql ﹣ secure ﹣ installation command for security initialization and boot

After setting, use the new password to log in again.
Setup self start:

chkconfig --add mysqld
chkconfig mysqld on

service mysqld start
service mysqld stop
service mysqld restart

In fact, Centos7 can already use system D to manage services and support self startup. mysql can also be used. For example, to install using the source version, you need to add the compile item - dwith UU systemd = 1. At the same time, configure a self named file under the directory / etc/systemd/system/mysqld.service.d, and then describe the following contents according to the actual situation:


Systemctl daemon reload

It can be seen that the download source installation on the official website supports the service configuration and management of chkconfig+service and systemd+systemctl, which need manual step-by-step practice, which is very helpful to understand the whole principle and process.

If the compiled binary downloaded from the official website is used for installation, only chkconfig+service and systemd+systemctl can be used for service configuration and management. If the rpm package downloaded from the official website is used for yum installation, systemd+systemctl can be directly used for service configuration and management.

After that, you can package the installation process and compiled files into an automatic installation script, install mysql database with one click, and manually configure and compile from scratch every time.

We will talk about some simple and practical commands of mysql in the next section, which are often used in actual combat.
