MySQL5.6的Linux安装之二进制安装（一）

2024-08-21 07:57:25 221人阅读

最近在写一个MySQL的shell安装脚本

说明一点着里面的所有路径都是绝对路径

下面来总结一下安装遇到的一些问题，以及安装的过程

这个是自带的安装过程

shell> groupadd mysql
shell> useradd -r -g mysql mysql
shell> cd /usr/local
shell> tar zxvf /path/to/mysql-VERSION-OS.tar.gz
shell> ln -s full-path-to-mysql-VERSION-OS mysql
shell> cd mysql
shell> chown -R mysql .
shell> chgrp -R mysql .
shell> scripts/mysql_install_db --user=mysql
shell> chown -R root .
shell> chown -R mysql data
shell> bin/mysqld_safe --user=mysql &
# Next command is optional
shell> cp support-files/mysql.server /etc/init.d/mysql.server

安装之前首先检查有没有mysql的进程，如果有我们还安装个啥

mysqlProcessNum=`/bin/ps aux | /bin/grep mysql | /usr/bin/wc -l | /bin/awk ‘{ print $1 }‘`;
if [ $mysqlProcessNum -gt 3 ]; then
    echo "已经安装MySQL"
    exit
fi

然后下载（可以从官网下载，但是个人感觉太慢了，于是就搭建了一个简单的ftp服务器，当然也可以本地上传嘛，在这里我就不细说了）

# download mysql package
yum install libaio   #MySQL的一个依赖包
/usr/bin/yum install awk wget -y
mysqlDownloadURL=ftp://。。。。。。。。。/pub/mysql/mysql-5.6.25-linux-glibc2.5-x86_64.tar.gz;
cd /tmp;
/bin/rm -rf mysql*.tar.gz
/usr/bin/wget $mysqlDownloadURL;

好我们已经下载好了

下面开始进入正题

解压，建立软连接

packageName=`/bin/ls | /bin/grep mysql*.tar.gz`;
# unpakcage mysql
/bin/tar zxvf $packageName -C /usr/local
mysqlAllNameDir=`/bin/ls -l /usr/local | grep mysql | /bin/awk ‘{ print $9 }‘`
/bin/ln -s $mysqlAllNameDir /usr/local/mysql

添加用户和用户组（判断一下，如果没添加就添加一下）

userNum=`/bin/cat /etc/passwd | /bin/grep mysql | /bin/awk -F ‘:‘ ‘{ print $1 }‘ | /usr/bin/wc -l`
if [ $userNum -lt 1 ];then
    /usr/sbin/groupadd mysql
    /usr/sbin/useradd -d /usr/local/mysql -s /sbin/nologin -g mysql mysql
    echo "成功添加"
fi

检查/etc下面是否有my.cnf文件，有的话就干掉，或者备份

/bin/mv /etc/my.cnf /etc/my.cnf.bak

下面初始化

/usr/local/mysql/scripts/mysql_install_db --datadir=/usr/local/mysql/data --user=mysql --basedir=/usr/local/mysql

说明一点！！！修改权限一定要在初始化之后，否则初始化之后的data目录不一定被附有权限

/bin/chown -R root.mysql /usr/local/mysql

/bin/chown -R mysql.mysql /usr/local/mysql/data/

现在可以自己写一个配置文件放在/etc下面

/etc/my.cnf （这里也说明一点，MySQL配置文件有参数替换原则）

顺序是这样的

/etc/my.cnf /etc/mysql/my.cnf /usr/local/mysql/etc/my.cnf ~/.my.cnf

[client]
socket=/usr/local/mysql/mysql-files/mysql.sock
[mysqld]
explicit_defaults_for_timestamp=true
datadir=/usr/local/mysql/data
socket=/usr/local/mysql/mysql-files/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# LOG
slow_query_log = 1
slow_query_log_file = /usr/local/mysql/mysql-files/mysql-slow.log
long_query_time = 2
# GENERAL LOG
#general_log = 1
#general_log_file = /usr/local/mysql/mysql-files/mysql-general.log
# BINARY LOG
server_id=101
log_bin=/usr/local/mysql/mysql-files/mysql-bin.log
binlog_format=ROW
sync_binlog=1
expire_logs_days=7
# ERROR LOG
log_error=/usr/local/mysql/mysql-files/mysql.err

# OTHER
character_set_server = utf8mb4
transaction-isolation = READ-COMMITTED
max_connections = 1000
log-queries-not-using-indexes
log_throttle_queries_not_using_indexes = 10

innodb_purge_threads=1 # SSD:4
innodb_lock_wait_timeout=3
innodb_print_all_deadlocks=1
pid-file=/usr/local/mysql/data/mysqld/mysqld.pid

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/usr/local/mysql/data/mysqld/mysqld.pid

下面以mysql_safe方式启动

/usr/local/mysql/bin/mysqld_safe &

好下面启动mysqld

/usr/local/mysql/bin/mysqld restart

[root@db mysql]# ./bin/mysql

mysql>

说明几点：

1.删除重新安装的时候一定要看看是不是mysqld 的进程全部杀死了（ps -ef|grep mysqld），如果有使用“kill -9 进程号”杀死不然会严重影响下次安装

2.可能是第二次在机器上安装mysql，有残余数据影响了服务的启动。去mysql的数据目录/data看看，如果存在mysql-bin.index，就删除掉

其他要说明的我在之前的安装过程中已经说明了

下面就是安装脚本的基本过程

#!/bin/bash
# mysql install script, the home directory is /usr/local/mysql-VERSION and the soft link is /usr/local/mysql
yum install libaio
/usr/bin/yum install awk wget -y
config=`/bin/pwd`
mysqlProcessNum=`/bin/ps aux | /bin/grep mysql | /usr/bin/wc -l | /bin/awk ‘{ print $1 }‘`;
if [ $mysqlProcessNum -gt 3 ]; then
    echo "已经安装MySQL"
fi

# download mysql package
mysqlDownloadURL=ftp://222.26.224.236/pub/mysql/mysql-5.6.25-linux-glibc2.5-x86_64.tar.gz;
cd /tmp;
/bin/rm -rf mysql*.tar.gz
/usr/bin/wget $mysqlDownloadURL;
packageName=`/bin/ls | /bin/grep mysql*.tar.gz`;
# unpakcage mysql
/bin/tar zxvf $packageName -C /usr/local
mysqlAllNameDir=`/bin/ls -l /usr/local | grep mysql | /bin/awk ‘{ print $9 }‘`
/bin/ln -s $mysqlAllNameDir /usr/local/mysql
userNum=`/bin/cat /etc/passwd | /bin/grep mysql | /bin/awk -F ‘:‘ ‘{ print $1 }‘ | /usr/bin/wc -l`
if [ $userNum -lt 1 ];then
    /usr/sbin/groupadd mysql
    /usr/sbin/useradd -d /usr/local/mysql -s /sbin/nologin -g mysql mysql
    echo "成功添加"
fi

#/bin/mv /etc/my.cnf /etc/my.cnf.bak

/usr/local/mysql/scripts/mysql_install_db --datadir=/usr/local/mysql/data --user=mysql --basedir=/usr/local/mysql
/bin/chown -R root.mysql /usr/local/mysql
/bin/chown -R mysql.mysql /usr/local/mysql/data/

#我的配置文件放到root目录下面了

/bin/cp $config/my.cnf /etc/　　　　

/usr/local/mysql/bin/mysqld_safe &

#/bin/chown -R mysql.mysql /usr/local/mysql/data/#/bin/cp $config/my.cnf /etc/
#cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
#chmod 755 /etc/init.d/mysqld

祝成功
