3、指定安装包路径
[[email protected]]#make -j 2 && make install
6、后端E主机编译安装二进制mysql数据库
执行此脚本可以编译安装完成二进制数据库。
[root@routersrc]#cd /usr/local/src 切换到此目录下
[root@routersrc]#tar -xvf mysql-5.6.34-onekey-install.tar.gz 解压数据库文件
[root@routersrc]#cat mysql-install.sh
#!/bin/bash
DIR=`pwd`
NAME="mysql-5.6.34-linux-glibc2.5-x86_64.tar.gz"
FULL_NAME=${DIR}/${NAME}
DATA_DIR="/data/mysql"
yum install vim gcc gcc-c++ wget autoconf net-tools lrzsz iotop lsof iotop bash-completion -y
yum install curl policycoreutils openssh-server openssh-clients postfix -y
if [ -f ${FULL_NAME} ];then
echo "安装文件存在"
else
echo "安装文件不存在"
exit 3
fi
if [ -h /usr/local/mysql ];then
echo "Mysql 已经安装"
exit 3
else
tar xvf ${FULL_NAME} -C /usr/local/src
ln -sv /usr/local/src/mysql-5.6.34-linux-glibc2.5-x86_64 /usr/local/mysql
if id mysql;then
echo "mysql 用户已经存在，跳过创建用户过程"
fi
useradd mysql -s /sbin/nologin
if id mysql;then
chown -R mysql.mysql /usr/local/mysql/* -R
if [ ! -d /data/mysql ];then
mkdir -pv /data/mysql && chown -R mysql.mysql /data -R
/usr/local/mysql/scripts/mysql_install_db --user=mysql --datadir=/data/mysql --basedir=/usr/local/mysql/
cp /usr/local/src/mysql-5.6.34-linux-glibc2.5-x86_64/support-files/mysql.server /etc/init.d/mysqld
chmod a+x /etc/init.d/mysqld
cp ${DIR}/my.cnf /etc/my.cnf
ln -sv /usr/local/mysql/bin/mysql /usr/bin/mysql
/etc/init.d/mysqld start
else
echo "MySQL数据目录已经存在,"
exit 3
fi
fi
fi
执行安装数据库脚本：
[root@routersrc]#bash mysql-install.sh
创建数据库，并创建一个数据库用户名及授权
[root@routersrc]#mysql Welcome to the MariaDB monitor. Commands end with ; or \g. Your MySQL connection id is 1 Server version: 5.6.34 MySQL Community Server (GPL) Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. MySQL [(none)]> create database wordpress; 创建数据库 Query OK, 1 row affected (0.00 sec) MySQL [(none)]> grant all on wordpress.* to "wordpress"@'192.168.37.%' identified by 'centos'; 创建数据库名称 Query OK, 0 rows affected (0.01 sec) MySQL [(none)]> flush privileges; 刷新数据库 Query OK, 0 rows affected (0.00 sec)
7、在后端E主机安装nfs共享包
1、安装nfs-utils包
[root@routersrc]#yum install nfs-utils -y
2、新建一个共享目录，并修改配置文件，将新建的目录共享出来，授予都写权限。
[root@routersrc]#mkdir /nfsdata/wordpress -p
修改配置文件，将目录共享
[root@routersrc]#vim /etc/exports /nfsdata/wordpress *(insecure,rw,async,no_root_squash) 避免客户端连接此nfs共享的目录是存在端口大于1024而被拒绝，需要加上insecure选项
3、启动nfs服务器，并设置为开机启动
[root@routersrc]#systemctl start nfs 如果需要重启nfs，最好是重新加载，避免重启带来重新注册端口。 [root@routersrc]#systemctl enable nfs
在E主机安装完成nfs之后，我们需要在A或B主机进行验证一下此nfs文件是否可以挂载，是否可以看到此目录。
在A主机安装nfs-utils包，然后挂载后端E主机的nfs路径，此时可以看到目录文件即可。
[root@centos7~]#yum install nfs-utils -y [root@centos7~]#showmount -e 192.168.37.47 查看nfs共享的目录 Export list for 192.168.37.47: /nfsdata/wordpress * 可以查看到nfs共享的目录 [root@centos7~]#mount -t nfs 192.168.37.47:/nfsdata/wordpress /mnt/ 测试挂载成功即可 [root@centos_17~]#umount /mnt 取消挂载
