mysql 在linux安裝Mysql 5.6.41

一：到mysql官網下載最新的mysql包

二：在linux /usr/local/中解壓mysql壓縮包 改名爲mysql
#  cd /usr/local/
#  tar -xzvf mysql  壓縮包名

三：創建用戶組mysql，創建用戶mysql並將其添加到用戶組mysql中，並賦予讀寫權限

# groupadd mysql --創建mysql用戶組組
# useradd -r -g mysql mysql --創建mysql用戶並添加到mysql用戶組中
# chown -R mysql mysql/ --將mysql目錄訪問權限賦爲myql用戶
# chgrp -R mysql mysql/ --改變mysql目錄的用戶組屬於mysql組

 

四：創建配置文件 保存並退出

# vim /etc/my.cnf
#複製以下內容 開始-----------------------------------
[client]
port = 3306
socket = /tmp/mysql.sock
[mysqld]
character_set_server=utf8
init_connect='SET NAMES utf8'
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
socket=/tmp/mysql.sock
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
#不區分大小寫
lower_case_table_names = 1
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
max_connections=5000
default-time_zone = '+8:00'

#複製以下內容 結束-----------------------------------

五：初始化數據庫

# /usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --lc_messages_dir=/usr/local/mysql/share --lc_messages=en_US

查看日記  cat /var/log/mysqld.log
看到有錯誤信息（第1次報錯）
2018-10-10 16:50:42 21449 [ERROR] Can't open the mysql.plugin table. Please run mysql_upgrade to create it.
於是上網找原因：
從報錯上來看，是由於缺少了mysql.plugin表所致的，不過現在連啓動都啓動不了，怎樣創建表呢？所以肯定是其他原因導致的，於時繼續網上找繼續試，最後找到了這個處理方法，進入mysql安裝後的目錄scripts執行以下語句：
# /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
又報錯下，如下:（第2次報錯）
FATAL ERROR: please install the following Perl modules before executing /usr/local/mysql/scripts/mysql_install_db:
Data::Dumper

好吧，繼續百度

解決方法 ：安裝autoconf庫

# yum -y install autoconf   //此包安裝時會安裝Data:Dumper模塊

六、配置環境變量
在文件中增加以下兩行：
export MYSQL_HOME="/usr/local/mysql"
export PATH="$PATH:$MYSQL_HOME/bin"

七、讓環境變量生效
#source /etc/profile

八、添加自啓動服務
#chkconfig --add mysql
#chkconfig mysql on

九、啓動mysql
#cd /user/local/mysql/bin
#service mysql start



十、增加root用戶密碼：
#cd /user/local/mysql/bin
#mysqladmin -u root password 'hww123456'
如果報mysqladmin：command not found
# ln -s /user/local/mysql/bin/mysql /usr/bin
# ln -fs /user/local/mysql/bin/mysql mysql 


十一、登錄mysql 創建用戶並賦予所有權限使得遠程可以訪問
#mysql -u root -p  
#GRANT ALL PRIVILEGES ON *.* TO test@"%" IDENTIFIED BY "123456"; 

 

後面按照上面的方式安裝不成功了，不知道啥原因，又有了下面的方式，步驟 一，二，三 是一樣的

cd mysql/scripts
[root@localhost scripts]# ./mysql_install_db --user=mysql --datadir=/usr/local/mysql/data/ --basedir=/usr/local/mysql
FATAL ERROR: please install the following Perl modules before executing ./mysql_install_db:
Data::Dumper

# yum -y install autoconf   //此包安裝時會安裝Data:Dumper模塊


[root@localhost scripts]# ./mysql_install_db --user=mysql --datadir=/usr/local/mysql/data/ --basedir=/usr/local/mysql
