MySQL5.7.20单实例二进制包安装

一、环境

OS: CentOS release 6.9 (Final)
MySQL: mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz

说明：类似的操作系统也可以的。为了方便起见，涉及到的操作，均可以直接粘贴复制，比较直观快捷的实施，我没有将带有命令行的截图或者文字粘贴出来。

可能会与路径有关，本文档是基于实践而记录下的，可能与你的环境有所不同，请遇到问题，具体分析查找资料。

二、准备工作

2.1、修改主机名称

hostname myserver
sed -i 's/shell/myserver/' /etc/sysconfig/network

2.2、关闭selinux

sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
setenforce  0

2.3、修改系统内核参数

cat >> /etc/sysctl.conf <

2.4、安装依赖包

# 需要配置yum

yum  clean all
yum -y update
yum -y install gd libxml2-devel libjpeg-devel libpng-devel net-snmp-devel wget telnet vim zip unzip 
yum -y install curl-devel libxslt-devel pcre-devel libjpeg libpng libcurl4-openssl-dev 
yum -y install libcurl-devel libcurl freetype-config freetype freetype-devel unixODBC libxslt 
yum -y install libtool openssl-devel
yum -y install perl-devel perl-ExtUtils-Embed 
yum -y install ncurses-devel.x86_64  openldap-devel.x86_64 lrzsz  openssh-clients gcc-g77  bison 
yum -y install libmcrypt libmcrypt-devel mhash mhash-devel bzip2 bzip2-devel
yum -y install ntpdate rsync svn  patch  iptables iptables-services
yum -y install libevent libevent-devel  cyrus-sasl cyrus-sasl-devel
yum -y install gd-devel libmemcached-devel memcached git libssl-devel libyaml-devel auto 
yum -y install gcc gcc-c++ make autoconf automake ncurses-devel ncurses  cmake libaio libaio-devel  boost
yum -y install perl-DBI perl-DBD-MySQL perl-Time-HiRes perl-IO-Socket-SSL perl perl-devel
yum -y groupinstall "Server Platform Development" "Development tools"
yum -y groupinstall "Development tools" 

2.5、基本初始化

mkdir -p /opt/mysql
cd /opt/mysql/
wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz
tar -zxf mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz
cd /usr/local/
ln -s /opt/mysql/mysql-5.7.20-linux-glibc2.12-x86_64 mysql

2.6、创建所需要的目录

mkdir -p /gomeo2o/data/mysql/mysql_3306/{data,logs,tmp}
mkdir -p /data/backup/

# 更改权限
groupadd mysql
useradd -g mysql mysql -d /home/mysql -s /sbin/nologin

2.7、创建配置文件

# 排除干扰因素

if [ -f /etc/my.cnf ]; then
    mv /etc/my.cnf /etc/my.cnf.bak
fi 

cat >/gomeo2o/data/mysql/mysql_3306/my_3306.cnf <

2.8、初始化数据库

chown -R mysql.mysql /gomeo2o/data
chown -R mysql.mysql /data/backup/
chmod -R 775 /data/backup/
/usr/local/mysql/bin/mysqld --defaults-file=/gomeo2o/data/mysql/mysql_3306/my_3306.cnf --initialize-insecure &

　# 查看日志
  # tail -f /gomeo2o/data/mysql/mysql_3306/logs/error.log

2.9、启动数据库推荐做法

/usr/local/mysql/bin/mysqld_safe --defaults-file=/gomeo2o/data/mysql/mysql_3306/my_3306.cnf & 

2.10、进入mysql,修改账号

/usr/local/mysql/bin/mysql  -uroot -p -P3306 -S /gomeo2o/data/mysql/mysql_3306/tmp/mysql_3306.sock

set sql_log_bin = 0;

set password=password('123456');

set password for 'root'@'%' = password('123456');

  update mysql.user set host = "%" where user='root';

grant all privileges on *.* to 'root'@'%' identified by 'root';

 select host,user,authentication_string,plugin from mysql.user;
create user 'rpl_user'@'%';
grant replication slave on *.* to 'rpl_user'@'10.%' identified by 'BR8KLwXCKHgN';
update mysql.user set authentication_string=password('rootpwd2017') where user='root';
flush privileges;
set sql_log_bin = 1;
reset  master ; reset slave all;
exit;
mysqldump --master-data --single-transaction --default-character-set=utf8 

$ mysqldump -h localhost -uroot -ppassword --master-data=2 --single-transaction --add-drop-table --create-options --quick \

--extended-insert --default-character-set=utf8 \

--databases discuz > backup-file.sql

######## 配置主从复制方法开始 ########
#    CHANGE MASTER TO MASTER_HOST='172.16.1.10',MASTER_USER='rpl_user',
#    MASTER_PASSWORD='BR8KLwXCKHgN',MASTER_PORT=3306,
#    MASTER_CONNECT_RETRY=10,MASTER_AUTO_POSITION =1;
#    
#    start slave;
#    show slave status\G;
######## 配置主从复制方法结束 ########

2.12、设置便捷使用方式

/usr/local/mysql/bin/mysql_config_editor set --host=localhost --login-path=3306_localhost_login --user=root --port=3306  --password --socket=/gomeo2o/data/mysql/mysql_3306/tmp/mysql_3306.sock

# 请输入root密码： rootpwd2017

alias mysql.3306.start='/usr/local/mysql/bin/mysqld_safe --defaults-file=/gomeo2o/data/mysql/mysql_3306/my_3306.cnf &'
alias mysql.3306.stop='/usr/local/mysql/bin/mysqladmin --defaults-file=/gomeo2o/data/mysql/mysql_3306/my_3306.cnf --login-path=3306_localhost_login shutdown &'
alias mysql.3306.login='/usr/local/mysql/bin/mysql --defaults-file=/gomeo2o/data/mysql/mysql_3306/my_3306.cnf --login-path=3306_localhost_login'
# alias mysql.3306.all_dump='/usr/local/mysql/bin/mysqldump --defaults-file=/gomeo2o/data/mysql/mysql_3306/my_3306.cnf --login-path=3306_localhost_login  -R -E --triggers -e --max_allowed_packet=16777216 --net_buffer_length=16384  --default-character-set=utf8mb4 --set-gtid-purged=OFF --master-data=2 --single-transaction --all-databases --quick | gzip >/data/backup/all_database_bak_`date +%Y-%m-%d_%H_%M_%S`.sql.gz'


cat  >>/root/.bashrc <>/etc/rc.local <

 四、配套卸载删除脚本

[root@myserver mysql]# sh Uninstall_mysql.sh 
  请注意,你正在关闭mysqld服务!!!
[Y/N]: Y
你已经选择关闭mysqld服务操作,即将关闭!!!
 1 2 3 4 5 6 7 8 9 10
mysql卸载完毕...

[root@myserver mysql]# chmod +x Uninstall_mysql.sh 

 

 

 

cat Uninstall_mysql.sh 
#!/bin/bash
mysqld_count=`ps -ef|grep -v 'grep' | grep mysqld |wc -l`
echo "  请注意,你正在关闭mysqld服务!!!"


function shutdown_and_delete_files () {

        /usr/local/mysql/bin/mysqladmin --defaults-file=/gomeo2o/data/mysql/mysql_3306/my_3306.cnf --login-path=3306_localhost_login shutdown &
fi

# 模拟打印进度条
for i in {1..10}
do 
        echo -n " $i"
        sleep 1
done

# 删除链接文件

if [ -L /usr/local/mysql ]; then
        unlink /usr/local/mysql
