1. 修改 SSH 连接显示字符集 （可以忽略这一步，偶尔出现乱码影响也不大的）# vi /etc/profile添加：LANG=zh_CN.GB2312export LANG使环境变量生效 保存后 断开 SSH 重新连接# source /etc/profi
1. 修改 SSH 连接显示字符集 （可以忽略这一步，偶尔出现乱码影响也不大的）
# vi /etc/profile
添加：
LANG=zh_CN.GB2312
export LANG
使环境变量生效 保存后 断开 SSH 重新连接
# source /etc/profile
注意：
如果有添加这一步，在设置 mysql 密码时会出现个 sql 编码问题，需要注释掉这里的设置断开ssh后重连就可以了
2. 设置时区
# cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
同步时间
# /usr/bin/rdate -s rdate.darkorb.net
写入 BIOS 避免失效
# hwclock -w
建议加入定时同步
# crontab -e
# 0 0 * * * /usr/bin/rdate -s rdate.darkorb.net
3. 配置服务器 yum 国内更新源地址
# cd /etc/yum.repos.d
# mv CentOS-Base.repo CentOS-Base.repo.bak
# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
# yum makecache
4. 更新软件和安装依赖包
# sudo -s
# LANG=C
# yum -y install 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 bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers ntpd nmap patch cmake bison cgi* *-gd-* libtool-* gettext *libxml-devel libcurl-devel libevent libevent-devel net-snmp-devel lsof unzip
如果出现错误 如：Error: Package: glibc-headers-2.12-1.80.el6_3.4.x86_64 (updates)
查看 http://www.zhouz.me/post/2012-10-25/40040279305
5. 设置路径
# vi /etc/ld.so.conf
添加：
/usr/lib/
/usr/local/lib/
/usr/lib64/
/usr/local/lib64/
6. 最好重启一次
# reboot
7. 开始安装 nginx
新建保存下载软件的目录
# mkdir -p /mydata/soft
# mkdir -p /var/www/html
# cd /mydata/soft/
下载：
# wget http://nginx.org/download/nginx-1.2.4.tar.gz
# wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.31.tar.gz
# wget https://gperftools.googlecode.com/files/gperftools-2.0.tar.gz
# wget http://download.savannah.gnu.org/releases/libunwind/libunwind-1.1.tar.gz
7.1 利用 TCMalloc 优化 nginx 性能
针对 64 位操作系统必须安装 libunwind 库
# tar zxvf libunwind-1.1.tar.gz
# cd libunwind-1.1/
# CFLAGS=-fPIC ./configure
# make CFLAGS=-fPIC
# make CFLAGS=-fPIC install
# cd ../
安装 google-perftools 优化
# tar zxvf gperftools-2.0.tar.gz
# cd gperftools-2.0/
# ./configure
# make && make install
# echo "/usr/local/lib" > /etc/ld.so.conf.d/usr_local_lib.conf
# /sbin/ldconfig
# cd ..
7.2 安装 pcre 使 nginx 支持 URL 重写
# tar zxvf pcre-8.31.tar.gz
# cd pcre-8.31
# ./configure
# make && make install
# cd ../
7.3 编译安装 nginx
# tar zxvf nginx-1.2.4.tar.gz
# cd nginx-1.2.4
# ./configure --prefix=/usr/local/nginx --with-google_perftools_module --user=www --group=www --with-http_stub_status_module --with-openssl=/usr/ --with-pcre=/mydata/soft/pcre-8.31
# make && make install
#cd ../
# mkdir /tmp/tcmalloc
# chmod 0777 /tmp/tcmalloc
7.4 添加用户和组
# /usr/sbin/groupadd www
# /usr/sbin/useradd -g www www
7.5 配置 nginx.conf
# vi /usr/local/nginx/conf/nginx.conf
注意：要在 pid 下一行添加下面的代码才能使优化生效
google_perftools_profiles /tmp/tcmalloc;
示例：替换为以下内容
user www www;
worker_processes 4;
worker_cpu_affinity 0001 0100 1000 0010;
error_log logs/error.log;
pid logs/nginx.pid;
worker_rlimit_nofile 65535;
google_perftools_profiles /tmp/tcmalloc;
events {
worker_connections 65535;
}
http {
#include deny_ips.conf;
include mime.types;
default_type application/octet-stream;
server_tokens off;
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;
server_names_hash_bucket_size 128;
client_header_buffer_size 32k;
large_client_header_buffers 4 32k;
client_max_body_size 50m;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 60;
fastcgi_connect_timeout 300;
fastcgi_send_timeout 300;
fastcgi_read_timeout 300;
fastcgi_buffer_size 64k;
fastcgi_buffers 4 64k;
fastcgi_busy_buffers_size 128k;
fastcgi_temp_file_write_size 256k;
fastcgi_intercept_errors on;
gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_http_version 1.0;
gzip_comp_level 2;
gzip_types text/plain application/x-javascript text/css application/xml;
gzip_vary on;
include vhost/*.conf;
}
7.6 启动 nginx
# ulimit -SHn 65535
# /usr/local/nginx/sbin/nginx
7.7 验证google-perftools是否已经正常加载 命令:
# lsof -n | grep tcmalloc
显示如下：
nginx 2395 nobody 9w REG 8,8 0 1599440 /tmp/tcmalloc.2395
nginx 2396 nobody 11w REG 8,8 0 1599443 /tmp/tcmalloc.2396
nginx 2397 nobody 13w REG 8,8 0 1599441 /tmp/tcmalloc.2397
nginx 2398 nobody 15w REG 8,8 0 1599442 /tmp/tcmalloc.2398
由于在Nginx配置文件中，设置worker_processes的值为4，因此开启了4个Nginx线程，每个线程会有一行记录。每个线程文件后面的数字值就是启动的Nginx的PID值。
至此，利用TCMalloc优化Nginx的操作完成。
7.8 优化 nginx 内核
# vi /etc/sysctl.conf
末尾添加：
net.ipv4.tcp_max_tw_buckets = 6000
net.ipv4.ip_local_port_range = 1024 65000
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_syncookies = 1
net.core.somaxconn = 262144
net.core.netdev_max_backlog = 262144
net.ipv4.tcp_max_orphans = 262144
net.ipv4.tcp_max_syn_backlog = 262144
net.ipv4.tcp_synack_retries = 1
net.ipv4.tcp_syn_retries = 1
net.ipv4.tcp_fin_timeout = 1
net.ipv4.tcp_keepalive_time = 30
刷新配置
# /sbin/sysctl -p
7.9 添加 nginx 的系统服务
之前在安装的时候写过了，详细内容可前往下面地址：
http://www.zhouz.me/post/2012-10-23/40041551802
7.10 添加各站点配置目录
# cd /usr/local/nginx/conf
# mkdir vhost
7.10.1 配置 localhost 站点
# vi vhost/localhost.conf
添加：
server
{
listen 80;
server_name localhost;
index index.html index.php;
root /var/www/html/;
#limit_conn crawler 20;
location ~ .*.(php|php5)?$
{
#fastcgi_pass unix:/tmp/php-cgi.sock;
#upload filesize limit
#client_max_body_size 10m;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
}
8. 安装 mysql
8.1 检测是否之前有安装过 rpm mysql包
查看系统是否有安装过 MySQL
注意大小写，如果mysql 不行就换MySQL
# rpm -qa | grep mysql
显示如：mysql-5.1.61-4.el6.x86_64
将搜索出的包名全部卸载：（nodeps表示强制删除），
例如：
# rpm -e --nodeps mysql-libs-5.1.61-4.el6.x86_64
8.2 下载 MySQL 相关软件包
# cd /mydata/soft
# wget http://www.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.28.tar.gz/from/http://cdn.mysql.com/
8.3 新建 MySQL 用户和组
# /usr/sbin/groupadd mysql
# /usr/sbin/useradd -g mysql mysql
8.4 新建目录并设置权限
# chmod +w /usr/local/mysql
# chown -R mysql:mysql /usr/local/mysql
# mkdir -p /var/mysql/data/
# mkdir -p /var/mysql/log/
# chown -R mysql:mysql /var/mysql/
# mkdir /home/mysql/temp
# chown -R mysql:mysql /home/mysql/temp
8.5 开始安装 MySQL
# tar xvf mysql-5.5.28.tar.gz
# cd mysql-5.5.28/
# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock

-DWITH_READLINE=1
-DENABLED_LOCAL_INFILE=1
-DMYSQL_USER=mysql
-DMYSQL_DATADIR=/var/mysql/data
# make && make install
8.6 配置 my.cnf 文件
# cd support-files/
注意：my-large.cnf 适用于1G内存左右的服务器，
可以根据自己配置情况选用 my-large.cnf 或 my-huge.cnf 等不同配置
# cp my-huge.cnf /etc/my.cnf
之前这里 my.cnf 的路径设置有问题（现已修改），导致没有生效，今天关闭 innodb 时才发现。。
是放在 etc 下面才会生效的。。
参考配置：关闭 innodb，binlog 保存 30 天内的
# vi /etc/my.cnf

# service mysqld start
# /usr/local/mysql/bin/mysqladmin -u root password "123456"
错误一：
mysqladmin, mysql ... 命令无法执行：
# export PATH=/usr/local/mysql/bin:$PATH
错误二：
Could NOT find Curses (missing: CURSES_LIBRARY CURSES_INCLUDE_PATH)
# yum install ncurses-devel
8.11 添加并发优化
# vi /usr/local/mysql/bin/mysqld_safe
在 executing mysqld_safe 的下一行，加上：
export LD_PRELOAD=/usr/local/lib/libtcmalloc.so
启动 mysql：
# service mysqld restart
使用lsof命令查看tcmalloc是否起效：
# /usr/sbin/lsof -n | grep tcmalloc

9.7 安装 PHP 扩展
9.7.1 服务器版 memcached
memcached 把我搞晕了，有两个 memcached，我也不是很清楚具体区别，
按我的理解应该是分为 服务器版 和 php 扩展版
一开始用 服务器版来编译 php 扩展，搞了半天都没弄出来，后来才发现居然有两个，晕死了
安装依赖包：
# tar zxvf libevent-2.0.20-stable.tar.gz
# cd libevent-2.0.20-stable
# ./configure --prefix=/usr/local/libevent
# make && make install
# cd ../
# tar xvzf memcached-1.4.15.tar.gz
# cd memcached-1.4.15
# ./configure --enable-64bit --enable-threads --with-libevent=/usr/local/libevent
# make && make install
# cd ../
检测是否安装成功：
# ls -al /usr/local/bin/memcached
# mkdir -p /var/run/memcached/
启动 memcached：
# /usr/local/bin/memcached -d -m 128 -u root -l 22.11.5.91 -p 11211 -c 256 -P /var/run/memcached/memcached.pid
# ps aux|grep memcached
关闭 memcached：
# kill `cat /var/run/memcached/memcached.pid`
新建启动和关闭脚本并赋执行权限：
# cp memcached-1.4.15/scripts/memcached.sysv /etc/init.d/memcached
# chmod 755 /etc/init.d/memcached
修改配置：
# vi /etc/init.d/memcached
修改：
PORT=11212
USER=root
OPTIONS=""
查找：
daemon memcached -d -p ....
修改为：
daemon /usr/local/bin/memcached -d -p ....
添加下面两行：
chown $USER /usr/local/bin/memcached
/usr/local/bin/memcached -d -p $PORT -u $USER -m $CACHESIZE -c $MAXCONN -P /var/run/memcache/memcached.pid $OPTIONS
添加到系统服务：
# chkconfig --add memcached
# chkconfig --level 2345 memcached on
# chkconfig --list memcached
测试启动 检测 关闭：
# service memcached start
# ps aux|grep memcached
# service memcached stop
开启防火墙外网访问（单机可忽略该设置）：
