1 搭建数据库 (192.168.37.108)
1.1 安装Mysql
使用脚本一键完成
将数据库软件包，脚本，配置文件my.cnf放在同一个目录中执行
#!/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 ×××tall vim gcc gcc-c++ wget autoconf net-tools lrzsz iotop lsof iotop bash-completion -y
yum ×××tall curl policycoreutils openssh-server openssh-clients postfix -y
yum ×××tall libaio -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_×××tall_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
1.2 创建wordpress数据库并授权
[root@s8 src]#mysql
mysql> CREATE DATABASE wordpress;
mysql> GRANT ALL PRIVILEGES ON wordpress.* TO "wordpress"@"192.168.37.%" IDENTIFIED BY "123456";
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| test |
| wordpress |
+--------------------+
5 rows in set (0.00 sec)
1.3 测试数据库连接
在wordpress服务器或者HAProxy服务器用授权帐号测试远程连接是否正满
[root@s0 ~]#mysql -uwordpress -p123456 -h192.168.37.108
MySQL [(none)]> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| test |
| wordpress |
+--------------------+
2 安装PHP 分别在两主机上完成相同的操作(192.168.37.103/104)
2.1 编译安装php
创建PHP,Nginx共同使用的系统帐号
[root@s4 ~]#useradd -s /sbin/nologin -u 1001
安装依赖包
[root@s3 src]#yum -y ×××tall wget vim pcre pcre-devel openssl openssl-devel libicu-devel gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel ncurses ncurses-devel curl curl-devel krb5-devel libidn libidn-devel openldap openldap-devel nss_ldap jemalloc-devel cmake boost-devel json automake libevent libevent-devel gd gd-devel libtool* libmcrypt libmcrypt-devel mcrypt mhash libxslt libxslt-devel readline readline-devel gmp gmp-devel libcurl libcurl-devel openjpeg-devel
[root@s3 src]#pwd
/usr/local/src
[root@s3 src]#tar xvf php-7.1.30
[root@s3 src]#cd php-7.1.30/
[root@s3 php-7.1.30]#./configure --prefix=/apps/php --enable-fpm --with-fpm-user=www --with-fpm-group=www --with-pear --with-curl --with-png-dir --with-freetype-dir --with-iconv --with-mhash --with-zlib --with-xmlrpc --with-xsl --with-openssl --with-mysqli --with-pdo-mysql --disable-debug --enable-zip --enable-sockets --enable-soap --enable-inline-optimization --enable-xml --enable-ftp --enable-exif --enable-wddx --enable-bcmath --enable-calendar --enable-shmop --enable-dba --enable-sysvsem --enable-sysvshm --enable-sysvmsg
[root@s3 src]make -j 2
[root@s3 src]make ×××tall
