playbook安裝分布式lnmp

搭建本地yum倉(cāng)庫(kù)，使用http發(fā)布

yum -y install httpd systemctl start httpd cd /var/www/html mkdir myrepoyum -y install createrepo createrepo myrepo [root@host103 html]# ls myrepo/repodata/cd myrepo #下載rpm 包 wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm rpm -Uvh http://download-ib01.fedoraproject.org/pub/epel/7/x86_64/Packages/l/libargon2-20161029-3.el7.x86_64.rpm rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpmyum install --downloadonly --downloaddir=/var/www/html/myrepo \ php72w php72w-cli php72w-common php72w-devel php72w-embedded php72w-gd php72w-mbstring php72w-pdo php72w-xml php72w-fpm php72w-mysqlnd php72w-opcache pcre-devel

編寫yum倉(cāng)庫(kù)配置

[root@host103 opt]# cat nginx.repo [nginx-stable] name=nginx stable repo baseurl=http://nginx.org/packages/centos/7/$basearch/ gpgcheck=0 enabled=1[root@host103 opt]# cat my.repo [myrepo] name=myrepo baseurl=http://192.168.23.103/myrepo enabled=1 gpgcheck=0

配置nginx配置文件，設(shè)置nginx支持php解析

[root@host103 opt]# egrep -nv '^$|#' default.conf 1:server { 2: listen 80; 3: server_name localhost; 7: location / { 8: root /usr/share/nginx/html;#修改 ,配置文首頁(yè)文件 9: index index.html index.php; 10: } 16: error_page 500 502 503 504 /50x.html; 17: location = /50x.html { 18: root /usr/share/nginx/html; 19: }#修改 29: location ~ \.php$ { 30: root html;#修改，配置php主機(jī)ip和默認(rèn)端口 31: fastcgi_pass 192.168.23.107:9000; 32: fastcgi_index index.php;#修改 33: fastcgi_param SCRIPT_FILENAME /usr/share/nginx/html$fastcgi_script_name; 34: include fastcgi_params; 35: } 43:}

配置php首頁(yè)文件

[root@host103 opt]# vim index.php <?php #配置連接數(shù)據(jù)的 ip 地址，用戶，密碼 $link=mysqli_connect('192.168.23.106','root','Admin@123'); if($link) echo "<h1>Success!!</h1>"; else echo "Fail!!"; ?>

配置nginx和mysql主機(jī)的nfs共享配置文件

[root@host103 opt]# cat nginx_exports /usr/share/nginx/html 192.168.23.0/24(rw,no_root_squash)[root@host103 opt]# cat mysql_exports /var/lib/mysql/ 192.168.23.0/24(rw,no_root_squash) [root@host103 opt]# cat www.conf | grep -v '^;' | grep -v '^$' [www] #修改，配置用戶和組為nginx user = nginx group = nginx #修改，配置監(jiān)聽(tīng)地址php的地址和端口 listen = 192.168.23.107:9000 #修改，設(shè)置為nginx主機(jī)的地址 listen.allowed_clients = 192.168.23.105 pm = dynamic pm.max_children = 50 pm.start_servers = 5 pm.min_spare_servers = 5 pm.max_spare_servers = 35 slowlog = /var/log/php-fpm/www-slow.log php_admin_value[error_log] = /var/log/php-fpm/www-error.log php_admin_flag[log_errors] = on php_value[session.save_handler] = files php_value[session.save_path] = /var/lib/php/session php_value[soap.wsdl_cache_dir] = /var/lib/php/wsdlcache [root@host103 opt]# cat /etc/php.ini | egrep 'mysqli.default_socket|date.timezone' ; http://php.net/date.timezone #修改，設(shè)置時(shí)區(qū) date.timezone = Asia/Shanghai #修改，設(shè)置mysql的套接字文件路徑 mysqli.default_socket = /var/lib/mysql/mysql.sock
