之前 写了个 426.【数据库】centos 7系统，二进制方式安装mysql ，很喜欢用二进制装mysql的方法，现在这个需求又出来了，我要装一个mysql在服务器上，于是乎，就想着这次把整个安装步骤，写出一个脚本出来。
直接上脚本：
#!/bin/bash #Program: # setup mysql #History: #2023/02/26 junfenghe.cloud@qq.com version:0.0.1 path=/bin:/sbin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:~/bin export path if [ -n "$1" ] then echo "mysql will be installed in $1" else echo "Please input path which mysql will be installed." echo "eg: $0 /usr/local" exit -1 fi type 'mysql' if [ $? -eq 0 ] then echo 'mysql has installed' echo 'please uninstall mysql such as: check /var/lib/mysql && /etc/profile && /etc/init.d/mysql.server && /var/log/mariadb' exit -1 fi bin=$(dirname ${BASH_SOURCE-$0}) bin=$(cd $bin ; pwd) cd $bin file_mysql=mysql-8.0.31-linux-glibc2.12-x86_64.tar.xz path_mysql=`echo $file_mysql | awk -F '.tar' '{print $1}'` path_mysql_full="$(cd $1 ; pwd)/$path_mysql" export PATH=$PATH:tmp/mysql-8.0.31-linux-glibc2.12-x86_64/bin msg_info="[INFO]" # check if exists group:mysql echo '@Step1 -> groupadd mysql' if_exists_group_mysql=$(cat /etc/group| grep mysql) if [ -n "${if_exists_group_mysql}" ] then echo ${msg_info}' group:mysql exists.' else groupadd mysql echo ${msg_info}' groupadd mysql ok.' fi if_exists_user_mysql=$(cat /etc/shadow | grep mysql) if [ -n "${if_exists_user_mysql}" ] then echo ${msg_info}‘ group:mysql exists’ else useradd -r -g mysql -s /bin/false mysql echo ${msg_info} ' useradd -r -g mysql -s /bin/false mysql ok' fi if [ -f $file_mysql ] then echo "exist "$file_mysql else wget "https://downloads.mysql.com/archives/get/p/23/file/$file_mysql" fi tar -xvf $file_mysql -C $1/ cd $1/$path_mysql mkdir -p mysql-files chown mysql:mysql mysql-files chmod 750 mysql-files yum install -y libaio ./bin/mysqld --initialize --user=mysql ./bin/mysql_ssl_rsa_setup mkdir -p /var/log/mariadb touch /var/log/mariadb/mariadb.log chown -R mysql:mysql /var/log/mariadb ./bin/mysqld_safe --user=mysql & #sed -i "s/basedir=\$/basedir=$(pwd)/g" support-files/mysql.server #sed -i "s/datadir=\$/basedir=$(pwd)\/data/g" support-files/mysql.server cp support-files/mysql.server /etc/init.d/mysql.server echo "export PATH=\$PATH:$path_mysql_full/bin" >> /etc/profile source /etc/profile echo 'Successfully!!!' echo 'you can execute [/etc/init.d/mysql.server start] to start mysql' exit 0
- 推荐执行的命令：
./scripts.sh '/usr/local/mysql' - 整个安装脚本是上一篇文章的完整命令整合的
- 脚本执行完毕之后，切记屏幕上会出现初始的root密码，不要看漏了，不然登录不上会有点麻烦，然后根据提示执行：
/etc/init.d/mysql.server start即可启动mysql。 - 如果启动有问题，可以根据脚本去修改
/etc/init.d/mysql.server。
