本次主要是mysql-5.5.54 的安裝

基礎(chǔ)環(huán)境為：

centos 6.8

一、下載mysql-5.5.54 安裝包

創(chuàng)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(chuàng)建用戶和組分區(qū)

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

make install

5、編寫(xiě)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

log-bin = /u01/app/mysql/log/mysql-binlog

log-bin-index = /u01/app/mysql/log/mysql-bin.index

binlog_cache_size = 32M

max_binlog_size=512M

binlog_format=row

innodb_file_per_table=1

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

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

skip-name-resolve

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

############pool#########

#*******skip-innodb*********

innodb_additional_mem_pool_size = 64M

innodb_buffer_pool_size=256M

innodb_write_io_threads = 8

innodb_read_io_threads = 8

innodb_thread_concurrency = 16

innodb_flush_log_at_trx_commit = 1

[mysqldump]

read_buffer = 32M

6、將mysql啟動(dòng)腳本腳本命令復(fù)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(jù)my.cnf 創(chuàng)建目錄他不會(huì)自動(dòng)創(chuàng)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(yǔ)句數(shù)據(jù)庫(kù)安裝指定的目錄，數(shù)據(jù)庫(kù)默認(rèn)存放目錄

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

更改環(huán)境變量

vim ~/.bash_profile

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

環(huán)境變量生效

source ~/.bash_profile

如果報(bào)錯(cuò)：

/etc/init.d/mysqld start

配置文件的問(wèn)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(shè)置的參數(shù)過(guò)大或者過(guò)小，查看機(jī)器內(nèi)存是否過(guò)小，如果都是可以的請(qǐng)刪除除了db 文件之外的所有然后重新創(chuàng)建目錄

##########啟動(dòng)成功之后設(shè)置密碼###########

mysqladmin -uroot password "123456"
