编译可能出现的问题
1111
错误 checking for XSL support... yes
configure: error: xslt-config not found. Please reinstall the libxslt >= 1.1.0 distribution 解决： yum -y install libxslt libxslt-devel
2222
错误
checking for libzip... not found
configure: error: Please reinstall the libzip distribution 解决：
这里不能这样子安装yum install -y libzip libzip-devel yum安装的版本低，不能用yum安装
下载 libzip-1.4.0.tar.gz （需要cmake 3.0以上） yum install cmake yum安装的版本低，不能用yum安装
先安装cmake高版本：卸载原有的yum -y remove cmake
下载包：
[root@webone.quan.bbs packages]$ curl -O https://cmake.org/files/v3.6/cmake-3.6.0-Linux-x86_64.tar.gz
[root@webone.quan.bbs packages]$tar -zxvf cmake-3.6.0-Linux-x86_64.tar.gz -C /usr/local/software/cmake
[root@webone.quan.bbs packages]$ln -s /usr/local/software/cmake/cmake-3.6.0-Linux-x86_64/bin/cmake /usr/bin/
注意：这个压缩包不是源码包，解压后直接用。
2222的第二步：正式安装libzip
[root@webtwo.quan.bbs packages]$wget https://libzip.org/download/libzip-1.4.0.tar.gz
[root@webtwo.quan.bbs packages]$tar -zxvf libzip-1.4.0.tar.gz
[root@webtwo.quan.bbs packages]$cd libzip-1.4.0
[root@webtwo.quan.bbs packages]$mkdir build
[root@webtwo.quan.bbs packages]$cd build
[root@webtwo.quan.bbs packages]$cmake ..
[root@webtwo.quan.bbs packages]$make && make install
33333
错误：
error: off_t undefined; check your library configuration 解决：
[root@webtwo.quan.bbs packages]$ vim /etc/ld.so.conf
添加以下内容：
/usr/local/lib64
/usr/local/lib
/usr/lib
/usr/lib64
[root@webtwo.quan.bbs packages]$ldconfig -v 立即生效
4444
错误：

^
compilation terminated.
make: *** [ext/zip/php_zip.lo] Error 1 解决：
cp /usr/local/lib/libzip/include/zipconf.h /usr/local/include/zipconf.h
编译成功后
[root@webtwo.quan.bbs packages]$make && make install
建立软连接+复制配置文件：
[root@webtwo.quan.bbs packages]$ ln -s /usr/local/software/php7.3.14 /usr/local/php
[root@webtwo.quan.bbs packages]$cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
[root@webtwo.quan.bbs packages]$cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf [root@webtwo.quan.bbs packages]$cd php-7.3.14
[root@webtwo.quan.bbs php-7.3.14]$cp php.ini-production /usr/local/php/lib/php.ini 由于编译的时候没有设置默认配置文件路径
/usr/local/php/lib 默认配置文件路径
cp php.ini-production /usr/local/php/lib/php.ini # 拷贝php-fpm进程服务的配置文件和扩展配置文件
cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
建立软连接 使命令支持
[root@webone.quan.bbs packages]$ ln -s /usr/local/php/bin/php /usr/bin/
加入服务，开机自启动：
[root@webone.quan.bbs packages]$cp /data/packages/php-7.3.14/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
[root@webone.quan.bbs packages]$chmod +x /etc/init.d/php-fpm
[root@webone.quan.bbs packages]$service php-fpm start
[root@webone.quan.bbs packages]$chkconfig php-fpm on
检测：
[root@webone.quan.bbs tmp]$ps aux |grep nginx

nginx 98612 0.0 0.2 47436 2288 ? S 20:37 0:00 nginx: worker process
nginx 和php 结合：
phpinfo()出现的问题：
1111
发现Loaded Configuration File => (none) ，表明没有载入php.ini文件
使用strace 追踪：
strace /usr/local/php7/sbin/php-fpm -i 2>1.log
vim 1.log 查看php.ini
发现
[root@webone.quan.bbs tmp]$php -i |grep php.ini
Configuration File (php.ini) Path => /usr/local/software/php7.3.14/lib
Loaded Configuration File => /usr/local/software/php7.3.14/lib/php.ini
将php.ini拷贝过去就行了
Mysql install 在主机192.168.111.151上操作
yum install openssl-devel -y
yum install -y ncurses-devel

编译成功后：

安装成功后，一如既往的建立软连接：
ln -s /usr/local/software/mysql-5.7.29 /usr/local/mysql
编写配置文件my,cnf
注意：再mysql5.7.18之后就源码包里面就没有mysql 配置文件的模板了
官网：https://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
可以yum 安装一个mysql ,将/etc/my.cnf复制来修改即可（记得卸载mysql）

安装mysql可能出现的问题：
1111问题：
[root@ansz.quan.bbs etc]$service mysqld start
Starting MySQL... ERROR! The server quit without updating PID file (/data/mysql/pids/mysql.pid).
[root@ansz.quan.bbs etc]$service mysqld status
ERROR! MySQL is not running, but lock file (/var/lock/subsys/mysql) exists
[root@ansz.quan.bbs etc]$service mysqld stop
ERROR! MySQL server PID file could not be found!
解决：
第一步建议查看/etc/my.cnf 因为我的编译的配置文件路径不是默认路径
以防万一，把他删了 第二部：建议查看系统是否自带安装了mysql ,卸载掉即可
第三步：系统可能已经存在正在运行的mysql 相关的程序，将其关掉

22222问题：
可能编译的时候，因为有参数：-DDOWNLOAD_BOOST=1 \
所以会在线下载文件boost_1_59_0.tar.gz 而这个文件的源有时载率是很低的，根本下载不了，所以只能大家多试几次了
解决：
其实因为我下载的myql版本是自带的，所以不需要加上面的参数-DDOWNLOAD_BOOST=1
然后直接编译就行了，哈哈哈哈哈哈哈哈哈哈哈

解决：
此处是因为我的配置文件建立的路径错误，导致初始化出现警告
但是是成功初始化的，因为i我的/etc/my.cnf是存在的，所以只警告 将/etc/my.cnf删除在，建立对的配置文件
注意：将数据库相关目录进行清空在初始化
本案例中包括/data/mysql/data 的文件
/data/mysql/logs的文件
/data/mysql/pids的文件

[apps@webone.quan.bbs etc]$cd /usr/local/nginx/html/
[apps@webone.quan.bbs html]$mkdir bbs 解压：
[root@webone.quan.bbs Discuz]$unzip Discuz_X3.4_SC_UTF8【20191201】.zip 将upload目录下的所有文件上传到bbs中 [root@webone.quan.bbs packages]$
cp -r /data/packages/Discuz/upload/* /usr/local/nginx/html/bbs/ 修改nginx配置文件：
user nginx nginx;
worker_processes 1; #error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info; #pid logs/nginx.pid; events {
worker_connections 1024;
} http {
include mime.types;
default_type application/octet-stream; #log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"'; #access_log logs/access.log main; sendfile on;
#tcp_nopush on; #keepalive_timeout 0;
keepalive_timeout 65; #gzip on; server {
listen 80;
server_name localhost; #charset koi8-r; #access_log logs/host.access.log main;
####修改这里，原来的location 可以不要了
index index.html index.htm index.php;
root /usr/local/nginx/html/bbs;
#error_page 404 /404.html; # redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
} # proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#} # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
####修改这里
fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html/bbs/$fastcgi_script_name;
include fastcgi_params;
} # deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
} # another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
# listen 8000;
# listen somename:8080;
# server_name somename alias another.alias; # location / {
# root html;
# index index.html index.htm;
# }
#} # HTTPS server
#
#server {
# listen 443 ssl;
# server_name localhost; # ssl_certificate cert.pem;
# ssl_certificate_key cert.key; # ssl_session_cache shared:SSL:1m;
# ssl_session_timeout 5m; # ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on; # location / {
# root html;
# index index.html index.htm;
# }
#} }
重启生效：
service nginx restart
