MySQL最新版本 MySQL5.7.11 批量自动化一键式安装

Posted 2020-09-06

以前都喜欢了源码安装MySQL，总觉得源码是高大上的事情，不过源码也需要时间，特别是make的时候，如果磁盘和cpu差的话，时间很长很长，在虚拟机上安装mysql尤其甚慢了。

 

现在业务发展了，开始在云上部署了，需要经常安装mysql，有的时候一次部署很多台，如果还是源码安装一个个去执行，效率就比较差了，所以准备采用更快效率的二进制来实现一键式自动化安装mysql。

 

1，mysql二进制安装包下载地址

下载地址：http://download.csdn.net/detail/mchdba/9488918，包括

1）  一键式自动安装脚本：auto_install_mysql5.7.sh;

2）  Mysql参数文件my.cnf

3）  Mysql5.7二进制安装包，在readme_mysql5.7_down_address.txt文件里面有下载地址连接，比mysql官网下载速度快很多倍。

 

PS：下载之后，将脚本已经所有软件放在同一个目录比如/soft目录下面。

2，自动化初始化linux服务器脚本

执行bash -x init_linux.sh就开始自动初始化Linux服务器了， 自动化安装脚本init_linux.sh如下，下载地址为http://download.csdn.NET/detail/mchdba/9488929：

#1 instal jdk , add tomcat user                                                                                sh init_jdk.sh   useradd tomcat mkdir -p /usr/local/app/ chown -R tomcat.tomcat /usr/local/app   #2 # vim /etc/sudoers echo "tomcat  ALL=(ALL)       ALL" >> /etc/sudoers   #3 set limits.conf echo "*    soft nofile 65536" >>  /etc/security/limits.conf echo "*    hard nofile 65536" >> /etc/security/limits.conf ulimit -a       #4 kernel optimization grep "net.ipv4.tcp_keepalive_time = 30" /etc/sysctl.conf if [ $? != 0 ]   then cat <<EOF>> /etc/sysctl.conf net.ipv4.tcp_max_tw_buckets = 6000 net.ipv4.ip_local_port_range = 1024 65000 net.ipv4.tcp_tw_recycle = 0 net.ipv4.tcp_tw_reuse = 1 net.core.somaxconn = 262144 net.core.netdev_max_backlog = 262144 net.ipv4.tcp_max_orphans = 262144 net.ipv4.tcp_max_syn_backlog = 262144 net.ipv4.tcp_synack_retries = 2 net.ipv4.tcp_syn_retries = 1 net.ipv4.tcp_fin_timeout = 1 net.ipv4.tcp_keepalive_time = 30 net.ipv4.tcp_keepalive_probes = 6 net.ipv4.tcp_keepalive_intvl = 5 net.ipv4.tcp_timestamps = 0 EOF     sed -i ‘s/net.bridge.bridge-nf-call-ip6tables = 0/#net.bridge.bridge-nf-call-ip6tables = 0/g‘ /etc/sysctl.conf sed -i ‘s/net.bridge.bridge-nf-call-iptables = 0/#net.bridge.bridge-nf-call-iptables = 0/g‘ /etc/sysctl.conf sed -i ‘s/net.bridge.bridge-nf-call-arptables = 0/#net.bridge.bridge-nf-call-arptables = 0/g‘ /etc/sysctl.conf fi   sysctl -p   #5 selinux disabled sed -i ‘s/SELINUX=enforcing/SELINUX=disabled/g‘ /etc/sysconfig/selinux sed -i ‘s/id:5:initdefault:/id:3:initdefault:/g‘ /etc/inittab   #6 stop some services service iptables stop sh stopservice.sh   #7 see the version #less /etc/issue   #8 set 90-nproc sed -i ‘s/*          soft    nproc     1024/#*          soft    nproc     1024/g‘   /etc/security/limits.d/90-nproc.conf sed -i ‘s/root       soft    nproc     unlimited/*       soft    nproc     unlimited/g‘   /etc/security/limits.d/90-nproc.conf   #9 system basic lib package install yum install gcc gcc-c++ ncurses-devel.x86_64 cmake.x86_64 libaio.x86_64 bison.x86_64 gcc-c++.x86_64 bind-utils wget curl curl-devel perl openssh-clients setuptool sysstat -y yum search rz -y yum install -y lrzsz.x86_64   #10 set shanghai time cp -f /usr/share/zoneinfo/Asia/Shanghai /etc/localtime hwclock   #11 restart the linux server shutdown -r now

 

3，自动化安装脚本

执行脚本bash  -x auto_install_mysql5.7.sh，开始一键式安装，自动化安装脚本如下：

# install the basie lib yum install cmake -y groupadd mysql useradd -g mysql mysql  autoreconf --force --install libtoolize --automake --force automake --force --add-missing yum install -y libtoolize yum install gcc gcc-c++ -y 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 make -y   # add mysql account,create the basic directory mkdir -p /data/mysql/data cd /data/mysql/data chown -R mysql.mysql /data chown -R mysql.mysql /usr/local/mysql5711 mkdir -p /data/mysql/binlog/ chown -R mysql.mysql /data/mysql/binlog/ cd /usr/local/mysql5711/   # init databases rm -rf /data/mysql/data/* cp my.cnf /usr/local/mysql5711/my.cnf time bin/mysqld --defaults-file=/usr/local/mysql5711/my.cnf --initialize --user=mysql   # set the auto start on linux server started cp support-files/mysql.server /etc/init.d/mysql chmod 700 /etc/init.d/mysql echo "export PATH=$PATH:/usr/local/mysql5711/bin">>/etc/profile source /etc/profile chkconfig --add mysql   # do a soft link to start mysql cd /usr/local/ ln -s /usr/local/mysql5711 mysql   # remove default my.cnf mv /etc/my.cnf /tmp/   # set the default password /usr/local/mysql/bin/mysqld_safe --skip-grant-tables --skip-networking & /usr/local/mysql/bin/mysql -uroot --password=‘‘ --socket=‘/usr/local/mysql/mysql.sock‘ -e " update mysql.user set authentication_string=password(‘dns_yuerld‘) where user=‘root‘ and Host = ‘localhost‘; flush privileges;" /usr/local/mysql/bin/mysql -uroot --password=‘dns_yuerld‘ --socket=‘/usr/local/mysql/mysql.sock‘ -e " set PASSWORD=PASSWORD(‘dns_yuerld‘); create database t; create table t1 select 1 as a; select * from t1;"   如果mysqld_safe启动失败，可以直接在my.cnf的mysqld选项卡里面添加skip-grant-tables=1，然后重启mysql，就可以无密码登陆进来。 # restart the mysql server service mysql restart   # check the test /usr/local/mysql/bin/mysql -uroot --password=‘dns_yuerld‘ --socket=‘/usr/local/mysql/mysql.sock‘ -e " select * from t1;"

 

4，批量安装很多mysql实例

将脚本和安装软件scp到N台服务器，然后ssh ip地址 " sh /soft/init_linux.sh; sh /soft/install_mysql.sh;"，用后台批量进程来安装。

5，why？采用二进制安装而不采用源码安装

主要是源码安装在make环节需要消耗太多时间，一次源码安装mysql需要很久，而二进制安装免去了configure、make、make install这一步骤，大大缩减了安装时间提升了效率，单台安装mysql感觉不大，如果一次性安装成千上万台，这个差距就是天上地下咯。

 

另外：安装过程中要实时查看控制台信息，如果有诡异的错误信息，要及时排查。
