How to install myql database for linux system in xshell

How to install myql database for linux system in xshell

Ideas:

step

1. Install mysql:
   1.1 Check the environment before installation, clear related mysql files and configuration files
   1.1.1 Check the current installation of mysql, and determine whether there is a myql database

mysql–version 这个是最好的
find / -name mysql  这个来查找文件
ps -ef |grep mysql  这个来看mysql的运行状态

The search results are as follows:


here it means that the myql file exists and is running.
Note: The myql rpm file is not installed here, so you can't use the following statement to check the statement: rpm -qa|grep -i mysql(This is only for rpm file detection, a bit unreliable) If you
have any questions, you can see this detailed uninstallation of mysql under Linux
1.1. 2 Close the mysql service, delete the myql file found

关闭服务： service mysqld stop

Result: Successfully shut down, if it fails, kill -9 pid process number will be used to shut down

删除文件： rm -rf 文件夹  来删除

Until all mysql-related files are deleted,

finally delete the my.cnf file.

rm -rf /etc/my.cnf

1.2 Install cmake compiler
1.2.1 Install compilation tools and library files

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-devel

1.2.2 Install cmake compiler
1 Download method wegt;
install wget statement# yum -y install wget

wget http://www.cmake.org/files/v3.1/cmake-3.1.1.tar.gz

State of normal startup

Picture of failed startup:

The reason is that the widget is not installed. There is no-check-certificate in the prompt of the reason error, which is usually not installed or damaged. re-install.

Download cmake statement:

wget http://www.cmake.org/files/v3.1/cmake-3.1.1.tar.gz

2. Unzip the installation packagetar zxvf cmake-3.1.1.tar.gz

3. Enter the installation package directory cd cmake-3.1.1
4. Compile and install

1  ./bootstrap
2   make && make install

1.3 Install mysql
1. Download address:

wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.15.tar.gz

2. Unzip the installation package
tar zxvf mysql-5.6.15.tar.gz

3. Enter the installation package directory cd mysql-5.6.15
4. Compile and install

 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

5. View the mysql version

/usr/local/webserver/mysql/bin/mysql --version

1.4
mysql configuration 1. Create user mysql for mysql operation:

1  /usr/sbin/groupadd mysql
2  /usr/sbin/useradd -g mysql mysql

2. Create the storage path of binlog and library and grant mysql user permissions

1    mkdir -p /usr/local/webserver/mysql/binlog /www/data_mysql
2   chown mysql.mysql /usr/local/webserver/mysql/binlog/ /www/data_mysql/

3. Create my.cnf configuration file

vim /etc/my.cnf

4. Initialize the database

/usr/local/webserver/mysql/scripts/mysql_install_db --defaults-file=/etc/my.cnf  --user=mysql

The above syntax error FATAL ERROR: Could not find ./bin/my_print_defaults Cause of the
problem: The file cannot be found in the absolute path during the operation, and the file is changed to the relative path.
Solution: Switch to the installation directory path (/usr/local/webserver/ mysql) under
./scripts/mysql_install_db --defaults-file=/etc/my.cnf --user=mysql
5. Create a boot script

cd /usr/local/webserver/mysql/
cp support-files/mysql.server /etc/rc.d/init.d/mysqld 
 chkconfig --add mysqld 
 chkconfig --level 35 mysqld on
 

6. Start the mysql server

service mysqld start

The above syntax error The server quit without updating PID file (/usr/local/webserver/mysql/mysql.pid). The
cause of the problem: there is no file mysql.pid in the view path, the mysql owner is root, and the mysql user does not have the creation permission
. : Give mysql the owner of the mysql folder, chown -R mysql:mysql mysql

7. Connect to MySQL

/usr/local/webserver/mysql/bin/mysql -u root -p

There is no password under the root user, press Enter to enter
8. Modify the password:
first log in to MySQL.
Format: mysql> set password for username@localhost = password('new password');

9. Add mysql to the linux environment variable, mysql -u username -p password takes effect

MYSQL_HOME=/usr/local/webserver/mysql
JAVA_HOME=/usr/local/src/jkd1.8
JAVA_BIN=/usr/local/src/jkd1.8/bin
PATH=$JAVA_HOME/bin:$PATH:$MYSQL_HOME/bin
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export JAVA_HOME JAVA_BIN PATH CLASSPATH MYSQL_HOME

10. Connect to external sql software. Open permissions:

grant all on *.* to
'root'@'%' identified by 'root';

11. Other commands
Start: service mysqld start
stop: service mysqld stop
restart: service mysqld restart
Reload configuration: service mysqld reload
