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

PHP安装时间较长
准备配置文件

[root@s3 php-7.1.30]#cd /apps/php/etc/php-fpm.d/
root@s3 php-fpm.d]#ll
total 40
-rw-r--r-- 1 www www 18760 Jun  9 13:01 www.conf.default
[root@s3 php-fpm.d]#cp www.conf.default www.conf
[root@s3 php-fpm.d]#cp /usr/local/src/php-7.1.30/php.ini-production  /apps/php/etc/php.ini

编辑配置文件

[root@s3 php-fpm.d]#vim www.conf
[www]
user = www
group = www
listen = 127.0.0.1:9000
listen.allowed_clients = 127.0.0.1
pm = dynamic
pm.max_children = 50
pm.start_servers = 30
pm.min_spare_servers = 30
pm.max_spare_servers = 35
pm.status_path = /pm_status
ping.path = /ping
ping.response = pong
access.log = log/$pool.access.log
slowlog = log/$pool.log.slow
[root@s3 php-fpm.d]#mkdir /apps/php/log/
root@s3 php-fpm.d]#cd /apps/php/etc/
[root@s3 etc]#ll
total 92
-rw-r--r-- 1 www www  1178 Jun  9 13:01 pear.conf
-rw-r--r-- 1 www www  4438 Jun  9 13:01 php-fpm.conf.default
drwxr-xr-x 2 www www    46 Jun 10 10:20 php-fpm.d
-rw-r--r-- 1 www www 72020 Jun  9 13:02 php.ini
[root@s3 etc]#cp php-fpm.conf.default php-fpm.conf

2.2 启动,测试PHP

检测语法 启动

[root@s3 etc]#/apps/php/sbin/php-fpm -t
[10-Jun-2019 10:28:47] NOTICE: configuration file /apps/php/etc/php-fpm.conf test is successful
[root@s3 etc]#/apps/php/sbin/php-fpm

www        6390   6386  0 06:56 ?        00:00:01 php-fpm: pool www
...

3 安装Nginx(192.168.37.103/104)

3.1 安装依赖包

[root@s3 src]#pwd
/usr/local/src
[root@s3 src]#yum ×××tall -y vim lrzsz tree screen psmisc lsof tcpdump wget ntpdate gcc gcc-c++ glibc glibc-devel pcre pcre-devel openssl openssl-devel systemd-devel net-tools iotop bc zip unzip zlib-devel bash-completion nfs-utils automake libxml2 libxml2-devel libxslt libxslt-devel perl perl-ExtUtils-Embed
[root@s3 src]#tar xvf nginx-1.14.2
[root@s3 src]#cd nginx-1.14.2/

3.2 自定义server信息

[root@s3 nginx-1.14.2]#vim src/core/nginx.h
 13 #define NGINX_VERSION      "000"
 14 #define NGINX_VER          "000" NGINX_VERSION

引号""中为Nginx版本信息,修改后安装会显示自己定义的Nginxt版本

[root@s3 nginx-1.14.2]#vim src/http/ngx_http_header_filter_module.c 
 49 static u_char ngx_http_server_string[] = "Server: Myserver" CRLF;

Server: 设置为自定义服务器信息

3.3 编译安装Nginx

[root@s3 nginx-1.14.2]#./configure --prefix=/apps/nginx --user=www --group=www --with-http_ssl_module --with-http_v2_module --with-http_realip_module --with-http_stub_status_module --with-http_gzip_static_module --with-pcre --with-stream --with-stream_ssl_module --with-stream_realip_module
[root@s3 nginx-1.14.2]#make
[root@s3 nginx-1.14.2]#make ×××tall

准备一个PHP测试页面

[root@s3 nginx-1.14.2]#mkdir /data/nginx/wordpress -p
[root@s3 nginx-1.14.2]#vim /data/nginx/wordpress/test.php
<?php
phpinfo();
?>

3.4 配置Nginx

设置启动帐号

[root@s3 nginx-1.14.2]#vim /apps/nginx/conf/nginx.conf
user  www www ;
worker_processes  1;

在http中设置server字段,设置监听域名www.a.net,主目录/data/nginx/wordpress index.php
并设置php转发

    server {
        listen       80;
        server_name  www.a.net;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root  /data/nginx/wordpress;
            index  index.php index.html index.htm;
        }

        location ~ \.php$ {
          root          /data/nginx/wordpress;
          fastcgi_pass  127.0.0.1:9000;
          fastcgi_index index.php;
          fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
          include       fastcgi_params;
        }

3.5 配置Nginx启动脚本

没有nginx.service文件就用vim创建一个

[root@s3 nginx-1.14.2]#cat /usr/lib/systemd/system/nginx.service 
[Unit]
Description=The nginx HTTP and reverse proxy server
After=network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
PIDFile=/apps/nginx/logs/nginx.pid
# Nginx will fail to start if /run/nginx.pid already exists but has the wrong
# SELinux context. This might happen when running `nginx -t` from the cmdline.
# https://bugzilla.redhat.com/show_bug.cgi?id=1268621
ExecStartPre=/usr/bin/rm -f /apps/nginx/logs/nginx.pid
ExecStartPre=/apps/nginx/sbin/nginx -t
ExecStart=/apps/nginx/sbin/nginx
ExecReload=/bin/kill -s HUP $MAINPID
#KillSignal=SIGQUIT
#TimeoutStopSec=5
KillMode=process
PrivateTmp=true
[Install]
WantedBy=multi-user.target

启动Nginx

[root@s3 nginx-1.14.2]#systemctl start nginx
[root@s3 nginx-1.14.2]#systemctl status nginx

查看服务是否正常启动

[root@s3 nginx-1.14.2]#ps -ef |grep nginx
root       6680      1  0 07:04 ?        00:00:00 nginx: master process /apps/nginx/sbin/nginx
www        6681   6680  0 07:04 ?        00:00:02 nginx: worker process
root       9495   7297  0 11:22 pts/0    00:00:00 grep --color=auto nginx

浏览器测试
图片不见了

4 部署WordPress

4.1 创建网站目录

[root@s3 nginx-1.14.2]#chown -R  www.www /data/nginx
[root@s3 nginx-1.14.2]#cd /data/nginx/
[root@s3 nginx]#tar xf wordpress-5.0.1-zh_CN.tar.gz
[root@s3 nginx]#chown -R www.www /data/
[root@s3 nginx]#cd wordpress
[root@s3 wordpress]#cp wp-config-sample.php wp-config.php

4.2 设置连接数据库

使用前的数据库帐号进行连接,通过keepalive服务器的VIP(192.168.37.240)连接数据库,不直接连接

[root@s3 wordpress]#vim  wp-config.php
...
define('DB_NAME', 'wordpress');

/** MySQL数据库用户名 */
define('DB_USER', 'wordpress');

/** MySQL数据库密码 */
define('DB_PASSWORD', '123456');

/** MySQL主机 */
define('DB_HOST', '192.168.37.240');

/** 创建数据表时默认的文字编码 */
define('DB_CHARSET', 'utf8');

/** 数据库整理类型。如不确定请勿更改 */
define('DB_COLLATE', '');

/**#@+
 * 身份认证密钥与盐。
 *
 * 修改为任意独一无二的字串!
 * 或者直接访问{@link https://api.wordpress.org/secret-key/1.1/salt/ WordPress.org密钥生成服务}
 * 任何修改都会导致所有cookies失效,所有用户将必须重新登录。
 *
 * @since 2.6.0
 */
define('AUTH_KEY',         '`plxTeyf>=SNRd|)F8PLSLO<Ixw<$}AB_o,ts}3 _-)hW)=Ue@<Ah>B#xl?|WlOG');
define('SECURE_AUTH_KEY',  '{Q>.,YBJbZKR.+Msb0RMV&6( P-(4_`zQgj@?{-A[=#<]~*[KVCW1?V!hF2d95:S');
define('LOGGED_IN_KEY',    '_N|`YMNp.4{ tBS,/sSP{H4g<-t@^z Afyv41:;=.F,4PPwI_4JGY5zUmsNXDToB');
define('NONCE_KEY',        'mF__L/-fP[2ouP Y&pY^)<S/flq=)Q-m1AwH&O`Sx-3#c? C6gpvK2|3zUgpISGB');
define('AUTH_SALT',        'mNDLO|3Ir:72N Mrdn?xAocUme?8/0K.ax>/Yp|0G18a8Pn8{ r@O$u&k1Z{>uso');
define('SECURE_AUTH_SALT', 'K0)Eb;ShB|4=7I]iAqi>v]cRkU7 #}/CwvcY?OAEwe+mr<T^C(DAA&Inw@u}IsWh');
define('LOGGED_IN_SALT',   'NgBg!C(7UJ>P{3|oS6J#svt3A>CC{m_QKkt?2eqzMI=TMuSw,PDW>!+ qz1e9U$l');
define('NONCE_SALT',       'C2&*P1]9Uo[|%b|fFJgMjIe1_Rs_(pb?:55ZXzjU;[Mutt:o~y1u@HB]eP.]z=Z)');
/**#@-*/

访问https://api.wordpress.org/secret-key/1.1/salt/生成密钥与盐
替换文件中的信息
其他的不用再修改
如果有多个wordpress 修改一下数据表前缀(多个wordpress放在一个服务器上才修改为不同的前缀)

/**
 * WordPress数据表前缀。
 *
 * 如果您有在同一数据库内安装多个WordPress的需求,请为每个WordPress设置
 * 不同的数据表前缀。前缀名只能为数字、字母加下划线。
 */
$table_prefix  = 'wp_';

5 设置haproxy (192.168.37.101/102)

因为要使用VIP,vip同一时间只能存在一台服务器上,没有VIP的一服务器会有故障。所以先打开两个系统设置,使其在没有VIP是不报故障

[root@s1 ~]#vim /etc/sysctl.conf
net.ipv4.ip_forward = 1
net.ipv4.ip_nonlocal_bind = 1
[root@s1 ~]#sysctl -p 
net.ipv4.ip_forward = 1
net.ipv4.ip_nonlocal_bind = 1

5.1 编译安装haproxy

5.1.1 安装依赖的工具包

yum ×××tall -y gcc gcc-c++ glibc glibc-devel pcre pcre-devel      openssl openssl-devel systemd-devel net-tools vim iotop bc zip unzip zlib-devel lrzsz tree screen lsof tcpdump wget ntpdate

5.1.2 安装haproxy

[root@s1 haproxy-1.8.20]#make ×××tall PREFIX=/usr/local/haproxy
[root@s1 haproxy-1.8.20]#useradd -s /sbin/nologin -u 2001 haproxy

5.1.3 设置启动脚本

[root@s1 haproxy-1.8.20]#cp haproxy /usr/sbin
[root@s1 haproxy-1.8.20]#vim /usr/lib/systemd/system/haproxy.service
[Unit]

7 挂载NFS文件存储

7.1 安装nfs-utils(192.168.37.107/103/104)

[root@s7 ~]#yum ×××tall nfs-utils

7.2 设置NFS同享

[root@s7 ~]#mkdir /data/nginx/wordpress
[root@s7 ~]#vim /etc/exports
/data/nginx/wordpress *(rw,no_root_squash)
[root@s7 ~]#exportfs -f

7.3 挂载NFS(192.168.37.103/104)

[root@s3 ~]#showmount -e 192.168.37.107
Export list for 192.168.37.107:
/data/nginx/wordpress *
[root@s3 ~]#mount 192.168.37.107:/data/nginx/wordpress /data/nginx/wordpress/wp-content/uploads/

验证

将自定义的域名在主机中解析为192.168.37.240
