HomeDatabaseMysql TutorialCentOS 6.5下编译安装MySQL 5.6.20

CentOS 6.5下通过yum安装的MySQL是5.1版的,比较老,所以就想通过源代码安装高版本的5.6.20。

概述:
CentOS 6.5下通过yum安装的MySQL是5.1版的,比较老,所以就想通过源代码安装高版本的5.6.20。

正文:
一:卸载旧版本
使用下面的命令检查是否安装有MySQL Server

rpm -qa | grep mysql有的话通过下面的命令来卸载掉

rpm -e mysql  //普通删除模式
rpm -e --nodeps mysql    // 强力删除模式,如果使用上面命令删除时,提示有依赖的其它文件,则用该命令可以对其进行强力删除二:安装MySQL
安装编译代码需要的包
yum -y install make gcc-c++ cmake bison-devel  ncurses-devel下载MySQL 5.6.14
wget
tar xvf mysql-5.6.20.tar.gz
cd mysql-5.6.20编译安装
cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DSYSCONFDIR=/etc \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DENABLE_DOWNLOADS=1 \
-DENABLED_LOCAL_INFILE=1 \
-DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock \
-DMYSQL_TCP_PORT=3306 \
-DEXTRA_CHARSETS=all \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci

make && make install编译的参数可以参考。

整个过程需要30分钟左右……漫长的等待

三:配置MySQL
设置权限
使用下面的命令查看是否有mysql用户及用户组

cat /etc/passwd 查看用户列表
cat /etc/group  查看用户组列表如果没有就创建

groupadd mysql
useradd -g mysql mysql修改/usr/local/mysql权限

chown -R mysql:mysql /usr/local/mysql修改/usr/local/mysql权限

初始化配置
进入安装路径

cd /usr/local/mysql进入安装路径,执行初始化配置脚本,创建系统自带的数据库和表

scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql注:在启动MySQL服务时,会按照一定次序搜索my.cnf,先在/etc目录下找,找不到则会搜索"$basedir/my.cnf",,在本例中就是 /usr/local/mysql/my.cnf,这是新版MySQL的配置文件的默认位置!注意:在CentOS 6.4版操作系统的最小安装完成后,在/etc目录下会存在一个my.cnf,需要将此文件更名为其他的名字,如:/etc/my.cnf.bak,否则,该文件会干扰源码安装的MySQL的正确配置,造成无法启动。

启动MySQL
添加服务,拷贝服务脚本到init.d目录,并设置开机启动

cp support-files/mysql.server /etc/init.d/mysql
chkconfig mysql on
service mysql start  --启动MySQL配置用户
MySQL启动成功后,root默认没有密码,我们需要设置root密码。

设置之前,我们需要先设置PATH,要不不能直接调用mysql

修改/etc/profile文件,在文件末尾添加

PATH=/usr/local/mysql/bin:$PATH
export PATH关闭文件,运行下面的命令,让配置立即生效

source /etc/profile现在,我们可以在终端内直接输入mysql进入,mysql的环境了

执行下面的命令修改root密码

mysql -uroot 
mysql> SET PASSWORD = PASSWORD('123456');若要设置root用户可以远程访问,执行

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'172.16.%' IDENTIFIED BY 'password' WITH GRANT OPTION;红色的password为远程访问时,root用户的密码,可以和本地不同。

配置防火墙
防火墙的3306端口默认没有开启,若要远程访问,需要开启这个端口

打开/etc/sysconfig/iptables

在“-A INPUT –m state --state NEW –m tcp –p –dport 22 –j ACCEPT”,下添加:

-A INPUT -m state --state NEW -m tcp -p -dport 3306 -j ACCEPT然后保存,并关闭该文件,在终端内运行下面的命令,刷新防火墙配置:

service iptables restart OK,一切配置完毕,你可以访问你的MySQL了~

Explain the InnoDB Buffer Pool and its importance for performance.Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
