騰訊雲雲主機全新環境安裝MySQL5.6.39

[root@VM_82_178_centos scripts]# cat /etc/redhat-release 
CentOS Linux release 7.4.1708 (Core)
磁盤偽雲盤40G
內存為2G

二、開始安裝：

上傳my.cnf模板文件到服務器/etc/下
上傳文件mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz到服務器root目錄下

useradd mysql -s /sbin/nologin -M
mkdir /data/mysql/{data,tmp,binlog,log} -p
chown -R mysql.mysql /data/mysql
tar xf /root/mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz -C /usr/local/
cd /usr/local/
mv mysql-5.6.39-linux-glibc2.12-x86_64  mysql
chown -R mysql.mysql /usr/local/mysql
cd /usr/local/mysql/scripts
 

2.1初始化報錯一

[root@VM_82_178_centos local]# cd /usr/local/mysql/scripts
報錯如下：
[root@VM_82_178_centos scripts]# ./mysql_install_db --datadir=/data/mysql/data --basedir=/usr/local/mysql --user=mysql --explicit_defaults_for_timestamp
FATAL ERROR: please install the following Perl modules before executing ./mysql_install_db:
Data::Dumper
[root@VM_82_178_centos scripts]# 
 

解決方法 ：安裝autoconf庫
命令: yum -y install autoconf //此包安裝時會安裝Data:Dumper模塊

yum -y install autoconf   

2.2初始化報錯二

重新執行初始化命令再次報錯：

[root@VM_82_178_centos scripts]# ./mysql_install_db --datadir=/data/mysql/data --basedir=/usr/local/mysql --user=mysql --explicit_defaults_for_timestamp
Installing MySQL system tables.../usr/local/mysql/bin/mysqld: error while loading shared libraries: libnuma.so.1: cannot open shared object file: No such file or directory
 

原因是這是缺少numactl。所以直接yum -y install numactl就可以解決這個問題了.

yum -y install numactl

再次初始化MySQL，此時初始化成功

三、準備啟動腳本並開啟MySQL服務

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chkconfig mysqld on
echo "export PATH=$PATH:/usr/local/mysql/bin" > /etc/profile.d/mysql.sh
source /etc/profile
/etc/init.d/mysqld restart
ps -ef|grep mysql

登錄MySQL給mysql初步優化：

drop database test;drop user root@‘::1‘;drop user ‘‘@‘localhost‘;drop user ‘‘@‘localhost.localdomain‘;drop user ‘root‘@‘localhost.localdomain‘; select user,host from mysql.user; flush privileges;

給MySQL服務設置登錄密碼：

mysqladmin -uroot password ‘123321123‘ 

到此處安裝完成

四、CentOS7.4上MySQL5.6.39快速安裝步驟：

useradd mysql -s /sbin/nologin -M
mkdir /data/mysql/{data,tmp,binlog,log} -p
chown -R mysql.mysql /data/mysql
yum -y install autoconf  numactl  libaio-devel 
tar xf /root/mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz -C /usr/local/
cd /usr/local/
mv mysql-5.6.39-linux-glibc2.12-x86_64  mysql
chown -R mysql.mysql /usr/local/mysql
cd /usr/local/mysql/scripts
./mysql_install_db --datadir=/data/mysql/data --basedir=/usr/local/mysql --user=mysql --explicit_defaults_for_timestamp
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chkconfig mysqld on
echo "export PATH=$PATH:/usr/local/mysql/bin" > /etc/profile.d/mysql.sh
source /etc/profile
/etc/init.d/mysqld restart
ps -ef|grep mysql

mysqladmin -uroot password ‘123321123‘ 

mysql -uroot -p‘123321123‘
mysql初步優化：
drop database test;drop user root@‘::1‘;drop user ‘‘@‘localhost‘;drop user ‘‘@‘localhost.localdomain‘;drop user ‘root‘@‘localhost.localdomain‘; select user,host from mysql.user; flush privileges;
