• CentOS7下搭建基本LNMP环境,部署WordPress


    系统环境:CentOS Linux release 7.4.1708 (Core) 3.10.0-693.el7.x86_64

    软件版本:nginx-1.12.2.tar.gz

         php 7.1.11

         mysql-community-server-5.7.20-1.el7.x86_64

    网络环境中配置了DNS服务器,本次nginx服务器的IP是192.168.1.20,域名是wp1.st.local。过程中全部使用域名配置或访问。

    一、安装nginx

    1、安装依赖及相关支持库

    # yum install pcre-devel pcre openssl openssl-devel

    2、编译安装nginx

    # cd nginx-1.12.2
    # ./configure 
      --prefix=/opt/nginx 
      --sbin-path=/usr/sbin/nginx 
      --user=nginx 
      --group=nginx 
     --pid-path=/var/run/nginx.pid 
     --lock-path=/var/run/nginx.lock 
      --with-http_ssl_module 
      --with-http_stub_status_module 
      --with-pcre 
      --error-log-path=/var/log/nginx/error.log 
      --http-log-path=/var/log/nginx/access.log 
      --with-http_gzip_static_module 
      --with-file-aio 
      --with-http_realip_module

    3、编译成功

    Configuration summary
      + using system PCRE library
      + using system OpenSSL library
      + using system zlib library
    
      nginx path prefix: "/opt/nginx"
      nginx binary file: "/usr/sbin/nginx"
      nginx modules path: "/opt/nginx/modules"
      nginx configuration prefix: "/opt/nginx/conf"
      nginx configuration file: "/opt/nginx/conf/nginx.conf"
      nginx pid file: "/var/run/nginx.pid"
      nginx error log file: "/var/log/nginx/error.log"
      nginx http access log file: "/var/log/nginx/access.log"
      nginx http client request body temporary files: "client_body_temp"
      nginx http proxy temporary files: "proxy_temp"
      nginx http fastcgi temporary files: "fastcgi_temp"
      nginx http uwsgi temporary files: "uwsgi_temp"
      nginx http scgi temporary files: "scgi_temp"

    4、安装

    # make && make install

    5、检验安装结果

    # nginx -V
    nginx version: nginx/1.12.2
    built by gcc 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) 
    built with OpenSSL 1.0.2k-fips  26 Jan 2017
    TLS SNI support enabled
    configure arguments: --prefix=/opt/nginx --sbin-path=/usr/sbin/nginx --user=nginx --group=nginx --with-http_ssl_module --with-http_stub_status_module --with-pcre --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --with-http_gzip_static_module --with-file-aio --with-http_realip_module --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock

    6、创建nginx用户

    # useradd -M -s /sbin/nologin nginx

    7、创建nginx的unit

    注意文件路径

    # vi /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=/run/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 /run/nginx.pid
    ExecStartPre=/usr/sbin/nginx -t
    ExecStart=/usr/sbin/nginx
    ExecReload=/bin/kill -s HUP $MAINPID
    KillSignal=SIGQUIT
    TimeoutStopSec=5
    KillMode=process
    PrivateTmp=true
    
    [Install]
    WantedBy=multi-user.target

    8、防火墙

    # iptables -I INPUT 5 -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
    # iptables-save >/etc/sysconfig/iptables

     9、配置nginx.conf语法高亮

    # wget http://www.vim.org/scripts/download_script.php?src_id=14376 -O /usr/share/vim/vim74/syntax/nginx.vim
    # vi /usr/share/vim/vim74/filetype.vim
    #追加一行,注意nginx的配置文件路径
    au BufRead,BufNewFile /opt/nginx/conf/* set ft=nginx

     10、修改配置文件

    # vi /opt/nginx/conf/nginx.conf
    
    user  nginx;
    worker_processes  auto;
    
        server {
            listen       80;
            server_name  wp1.st.local;        #配置域名
            location / {
                root   html;
                index  index.php index.html index.htm;        #增加index.php
            }
            error_page   500 502 503 504  /50x.html;
            location = /50x.html {
                root   html;
            }

    11、启动服务

    # systemctl start nginx.service
    # systemctl enable nginx.service

    12、访问测试

     二、安装PHP

    1、添加扩展源

    # yum -y install https://mirror.webtatic.com/yum/el7/epel-release.rpm https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

    2、安装支持库

    # yum install libxml2 libxml2-devel libpng libpng-devel libcurl-devel libcurl libzip-devel libzip gd bzip2-devel bzip2

    3、安装PHP7.1及相关支持

    # yum -y install mod_php71w php71w-mbstring php71w-pear php71w-fpm php71w-gd php71w-pdo 

    php71w-mysql放在安装MySQL时一起安装,因为在未添加mysql57源的时候,可能会安装mariadb-libs作为mysql-community-libs的替代。

    4、修改配置文件

    # vi /etc/php-fpm.d/www.conf
    
    #指定用户为前面创建的nginx
    user = nginx
    group = nginx

    修改nginx.conf,root最好填写绝对路径,document_root就是root选项的指定目录

    #添加
    location ~ .php$ {
                root           /opt/nginx/html;
                fastcgi_pass   127.0.0.1:9000;
                fastcgi_index  index.php;
                fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
                include        fastcgi_params;
            }

    修改所属用户为nginx

    # chown -R nginx. /var/lib/php
    # chown -R nginx. /opt/nginx/html

    5、启动php-fpm,重载nginx

    # systemctl start php-fpm.service 
    # systemctl enable php-fpm.service
    # systemctl reload nginx.service

    6、访问测试

    # /opt/nginx/html/index.php
    
    <?php
        phpinfo();
    ?>

    注意权限

    # chown nginx. index.php

    三、安装MySQL5.7

    1、添加扩展源

    # vi /etc/yum.repos.d/mysql-community.repo
    
    [mysql57-community]
    name=MySQL 5.7 Community Server
    baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/7/$basearch/
    enabled=1
    gpgcheck=1
    gpgkey=http://repo.mysql.com/RPM-GPG-KEY-mysql

    2、安装MySQL

    # yum -y install mysql-community-server php71w-mysql

    3、启动并配置

    # vi /etc/my.cnf
    #添加一行
    character-set-server=utf8
    # systemctl start mysqld

    通过mysql_secure_installation命令按提示设置root密码以及基础的MySQL配置

    4、创建数据库和新用户

    mysql> create database wordpress;    
    mysql> create user 'wp_user'@'%' identified by 'xxxxxxxx';    #创建用户
    mysql> grant all privileges on wordpress.* to 'wp_user'@'%' identified by 'xxxxxxxx';    #授权
    mysql> flush privileges;

    5、重置MySQL的用户密码

    如果忘记MySQL密码,就使用如下办法重置。需要root权限

    #vi /etc/my.cnf
    [mysqld]
    skip-grant-tables
    #mysql -uroot
    mysql> use mysql;
    mysql> update user set authentication_string=password('xxxxxxxx') where user='root';    #5.7版本的密码字段是authentication_string,而不是password
    mysql> flush privileges;

    修改完后注释掉skip-grant-tables,重启mysqld.service

     四、安装WordPress

    1、下载并解压

    # wget https://cn.wordpress.org/wordpress-4.9.1-zh_CN.zip
    # unzip wordpress-4.9.1-zh_CN.zip
    # cp -rva wordpress/* /opt/nginx/html/

    2、修改用户和组

    # chown nginx. /opt/nginx/html

    3、SELINUX

    # cd /opt/nginx
    # chcon -R -t httpd_sys_content_t html/
    # cd html/
    # chcon -R -t httpd_sys_rw_content_t wp-content/

    通过编译安装的nginx与yum安装的的安全上下文有所不同,yum安装会自动配置正确的上下文,编译安装默认可能是admin_home_t,访问时会提示File not found,必须改为httpd_sys_content_t

    4、按照提示部署WordPress

    五、配置nginx虚拟机

    1、添加配置

    虚拟server都可以配置为80端口,配置不同的域名

    # mkdir /opt/nginx/conf.d
    # vi /opt/nginx/conf.d/virtual1.conf
    server {
        listen       80;
        server_name  bbs.st.local;
    
        location / {
            root   /opt/nginx/virtual;
            index  index.html index.htm;
        }
    }
    #在nginx.conf全局区块中包含配置文件
    # vi /opt/nginx/conf/nginx.conf
    include /opt/nginx/conf.d/*.conf;

    2、创建虚拟主机目录并修改权限

    # mkdir /opt/nginx/virtual
    # vi /opt/nginx/virtual/index.html
    Nginx Virtual Host Test Page
    # chown -R nginx. /opt/nginx/virtual/
    # chcon -R -t httpd_sys_content_t /opt/nginx/virtual/

    3、重载服务

    # systemctl reload nginx.service

    4、结果检测
