安裝MySQL 教程詳解

發布時間:2020-04-28 11:50:03 來源:億速云 閱讀:255 作者:三月 欄目:數據庫

本文主要給大家介紹安裝MySQL 教程詳解,希望可以給大家補充和更新些知識,如有其它問題需要了解的可以持續在億速云行業資訊里面關注我的更新文章的。

 本次主要是mysql-5.5.54 的安裝

基礎環境為:

                  centos 6.8 

 一、下載mysql-5.5.54 安裝包

       創建軟件存放目錄

                    mkdir /home/softwares/

                    cd  /home/softwares/

                    wget  http://dev.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.54.tar.gz

二、安裝mysql 依賴包

                    yum install -y cmake;

                    yum install -y gcc gcc-c++ ;

                    yum install -y ncurses-devel.x86_64 ;

                    yum install -y cmake.x86_64 ;

                    yum install -y libaio.x86_64 ;

                    yum install -y bison.x86_64 ;

                    yum install -y gcc-c++.x86_64;

                    yum install -y perl-Module-Build;

                    yum install -y libtool zilib-devel ;

                    yum install -y libaio.x86_64;

                    yum install -y perl.x86_64;

                    yum install -y perl-Module-Pluggable.x86_64;

                    yum install -y perl-Pod-Escapes.x86_64;

                    yum install -y perl-Pod-Simple.x86_64;

                    yum install -y perl-libs.x86_64;

                    yum install -y perl-version.x86_64  ;

                    yum install –y openssl openssl-devel ncurses ncurses-devel;

            2、創建用戶和組分區

                   groupadd mysql  

                   useradd mysql -g mysql -M -s /sbin/nologin

            3、解壓mysql-5.5.54.tar.gz

                   tar -zxvf mysql-5.5.54.tar.gz && cd mysql-5.5.54/  && chmod +x *

            4、編譯安裝

安裝MySQL 教程詳解

cmake \ ##相當于config
-DCMAKE_INSTALL_PREFIX=/u01/app/mysql/db \   ##數據庫安裝的目錄
-DSYSCONFDIR=/u01/app/mysql/db/etc \       ##數據庫安裝的配置文件,不用原來的默認文件可以避免多次升級的時候讀取錯誤的配置文件
-DMYSQL_DATADIR=/u01/data/mysql/db/data \ ##數據庫默認存放庫表存放的位置
-DWITH_MYISAM_STORAGE_ENGINE=1 \ 
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DMYSQL_UNIX_ADDR=/u01/app/mysql/db/mysql.sock \ ##本地通信日志
-DMYSQL_TCP_PORT=3306 \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DEXTRA_CHARSETS=all \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \

             make  install

           5、編寫配置文件

                cd /u01/app/mysql/db/  &&  mkdir etc && cd etc

                mkdir etc

                vi my.cnf

cat my.cnf 

[mysqld]

#########data###########

user=mysql

basedir = /u01/app/mysql/db

datadir = /u01/app/mysql/data

innodb_log_group_home_dir=/u01/app/mysql/engine/innolog

innodb_log_file_size = 50M

innodb_data_home_dir=/u01/app/mysql/engine/innodata

#innodb_data_file_path = ibdata1:100M;ibdata2:150M:autoextend

innodb_data_file_path = ibdata1:100M:autoextend

innodb_file_per_table=1

log-error = /u01/app/mysql/mysql-error.log

pid-file = /u01/app/mysql/mysql.pid

innodb_write_io_threads = 8

innodb_read_io_threads = 8

write_buffer = 32M

[mysqlhotcopy]

interactive-timeout

[client]

socket=/u01/app/mysql/mysql.sock

port=3306

           6、將mysql啟動腳本腳本命令復制到/etc/init.d/

                cp /u01/app/mysql/db/support-files/mysql.server  /etc/init.d/mysqld && chmod +x                 /etc/init.d/mysqld

                chmod +x /etc/init.d/mysqld

               

           7、根據my.cnf 創建目錄他不會自動創建目錄

               mkdir -p /u01/app/mysql/data/engine/innolog

               mkdir -p /u01/app/mysql/data/engine/innodata

               mkdir -p /u01/app/mysql/data/mysql-binlog

               mkdir -p /u01/app/mysql/log/

               chown mysql. /u01/app/mysql/ -R

                cd /u01/app/mysql/db

          8、初始化語句數據庫安裝指定的目錄,數據庫默認存放目錄

               ./scripts/mysql_install_db --basedir=/u01/app/mysql/db --datadir=/u01/app/mysql/data --user=mysql

           更改環境變量

            vim ~/.bash_profile

            PATH=$PATH:$HOME/bin:/u01/app/mysql/db/bin/

            環境變量生效

             source ~/.bash_profile

            如果報錯:

 /etc/init.d/mysqld start

 配置文件的問題

 Starting MySQL... ERROR! The server quit without updating PID file (/data/mysql/mysql.pid).

一般需要自己查詢配置文件是否設置的參數過大或者過小,查看機器內存是否過小,如果都是可以的請刪除除了db 文件之外的所有 然后重新創建目錄

              ##########啟動成功之后設置密碼###########

                mysqladmin -uroot password "123456"
